3. Precautions
To get the optimum performance from the balance and acquire accurate weighing data, note
the following:
3-1. Before Use
The maximum resolution of the precision balance is ten million counts. Therefore, there are
tendencies to be influenced by temperature change, air pressure change, static electrisity,
vibration and drafts where the balance is placed.
Install the balance in an environment where the temperature and humidity are not excessive.
The best operating temperature is about 20°C / 68°F at about 50% relative humidity.
Install the balance where it is not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
Install the balance where it is free of dust.
Install the balance away from equipment that produces magnetic fields.
Install the balance in a stable place avoiding vibration and shock. Corners of rooms on the
first floor are best, as they are less prone to vibration.
The weighing table should be solid and free from vibration, drafts and as level as possible.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.
If static electricity is a problem at the installation site, use the electrostatic field meter and the
static eliminator.
Ensure a stable power source when using the AC adapter.
Connect the AC adapter and warm up the balance for at least 30 minutes.
Calibrate the balance periodically for accurate weighing.
When the balance is installed for the first time or has been moved, warm up the balance for
at least 6 hours to allow the balance to reach equilibrium with the ambient temperature, and
then perform calibration before use.
The meaning of IP-65 is "No ingress of dust. Projected against water jets".
If a powerful water jet is used or the balance is immersed in water, it may cause a damage
that is due to ingress of water.
Confirm that "the plug is inserted firmly into the jack" and "the terminal is covered using the
waterproof cover or the waterproof RS-232C cable (GX-07K)", when using the balance.
Use the waterproof option cable GX-07K, when the RS-232C interface is used with IP-65.
AX-KO1710-200, a standard RS-232C cable, is not waterproof or dustproof.
Confirm that the weighing pan does not touch to rim.
Do not install the balance where flammable or corrosive gas is present.

3-2. During Use
Discharge static electricity from the weighing material. When
weighing sample (plastics, insulator, etc.) could have a static
charge, the weighing value is influenced. Ground the balance, and
Eliminate the static electricity by using an optinal static
eliminator, AD-1683.
Or try to keep the ambient humidity above 45%RH at the room.
Or use the metal shield case.
Or wipe a charged material (plastic sample etc.) with the wet cloth.
This balance uses a strong magnet as part of the balance
assembly, so please use caution when weighing magnetic
materials such as iron. If there is a problem, use the underhook on
the bottom of the balance to suspend the material away from the
influence of the magnet.
Eliminate any temperature difference between the sample and the
environment. When a sample is warmer (cooler) than the ambient
temperature, the sample will be lighter (heavier) than the true
weight. This error is due to a rising (falling) draft around the sample.
Make each weighing gently and quickly to avoid errors due to
changes in the environmental conditions.
Do not drop things upon the weighing pan, or place a sample on
the pan that is beyond the balance weighing capacity. Place the
sample in the center of the weighing pan.
Do not use a sharp instrument such as a pencil to press the keys.
Use your finger only.
Press the RE-ZERO key before each weighing to prevent
possible errors.
Calibrate the balance periodically so as to eliminate possible errors.
Take into consideration the affect of air buoyancy on a sample
when more accuracy is required.
It is possible to check the reference card for principle operation.
Prevent foreign matter, such as powder, liquid and metal, from invading the area around
the weighing pan.
Use the "breeze break" for a precision weighing.
3-3. After Use
Avoid mechanical shock to the balance.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service
or repair.
Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that
is moistened with warm water and a mild detergent.

Do not allow the balance to be immersed in water. Even though the balance complies with
IP code, the balance will not withstand being completely immersed in water.
The weighing pan, pan support and draft gate can be removed to clean the balance. Clean
by splashing with water.
Use the waterproof option RS-232C cable GX-07K, when RS-232C interface is used with
IP-65. AX-KO1710-200, a standard RS-232C cable, is not waterproof or dustproof.
3-4. Power Supply
Do not remove the AC adapter while the internal mass is in motion, for example, right
after the AC adapter is connected, or during calibration using the internal mass.
If the AC adapter is removed under the conditions described above, the internal mass will be
left unsecured, that may cause mechanical damage when the balance is moved. Before
removing the AC adapter, press the ON:OFF key and confirm that zero is displayed.
When the AC adapter is connected, the balance is in the standby mode if the standby
indicator is on. This is a normal state and does not harm the balance. For accurate
weighing, keep the AC adapter connected to the balance and AC power unless the
balance is not to be used for a long period of time.

9-3. Description of the Class "Environment, Display"
Condition ( Cond )
Cond 0 | This parameter is for sensitive response to the fluctuation of a weight value. Used for powder target weighing, weighing a very light sample or when quick response weighing is required. After setting, the balance displays FAST. This parameter is for stable weighing with slow response. Used to prevent a |
Cond 2 |
weight value from drifting due to vibration or drafts. After setting, the balance
displays SLOW.
Notes In automatic response adjustment, the weighing speed is selected
automatically.
With "Hold function (Hold)" set to "ON (1)", this item is used to set the
averaging time.
Stability band width ( 5t-b )
This item controls the width to regard a weight value as a stable value. When the fluctuation
per second is less than the parameter, the balance displays the stabilization indicator and
outputs or stores the data. The parameter influences the "Auto print mode"
5t-b 0 This parameter is used for sensitive response of the stabilization indicator. Used
for exact weighing.
5t-b 2 This parameter ignores slight fluctuation of a weight value. Used to prevent a
weight value from drifting due to vibration or drafts.
Note | With "Hold function (Hold)" set to "ON (1)", this item is used to set the stabilization range. |
Zero upon power-on ( p-tr )
When a hopper is attached to the weighing pan and loss-in weighing is performed, the
remaining amount of the material will become unknown if tare is performed each time a
weighing starts.
When " p-tr " is set to “ 1 ”, tare is not performed at weighing start. So, the remaining amount of
the material can be monitored, when the power is turned on again after it was turned off.
Span calibration ( 5pn )
When a hopper is attached to the weighing pan and calibration is to be performed with the
hopper attached, set " 5pn " to “ 1 ”. When the tare value (hopper and other devices attached) is
within the value in the table below, calibration using the internal mass is possible.
Model | Tare value |
MC-10K | 9 kg or less |
MC-30K | 29 kg or less |

11-2-2. Connection to a Computer and the Use of WinCT
The balance is of the DCE type (Data Communication Equipment), which can be connected
to a personal computer using the RS-232C interface. Before connection, read the personal
computer manual thoroughly. Use a standard DCE cable for connection (cable type:
straight-through). When the personal computer type is a DOS/V with a 9-pin port, use a
straight-through cable with a 25-pin male connector and a 9-pin female connector.
Using Windows Communication Tools Software (WinCT)
When Windows is used as an operating system in a personal computer, the provided
WinCT software can be used to transmit the weighing data to the personal computer.
The WinCT software has two communication methods: "RsCom" and "RsKey". Refer to the
WinCT instruction manual.
RsCom
RsCom can transmit commands to control the balance.
RsCom can perform bi-directional communication between the balance and a personal
computer using the RS-232C interface.
RsCom can display or store the data using a text file format. RsCom can also print the data
using a printer connected to the personal computer.
When several ports of a personal computer have balances connected, can communicate
with each balance simultaneously.
RsCom can share a personal computer with other application software.
RsCom can receive the balance GLP report.
RsKey
RsKey can transmit the weighing data output from the balance directly to other application
software such as Microsoft Excel.
RsKey can be used with most application software.
RsKey can receive the balance GLP report.
Using the WinCT software, the balance can do the following:
Analyzing the weighing data and the statistics with "RsKey"
The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze
the data to obtain total, average, standard deviation, maximum and minimum value, and
display them in a graph.
Controlling the balance using commands from a personal computer
By using "RsCom", the personal computer sends commands such as "re-zero" or "send
weighing data" to the balance and controls the balance.
Printing the balance GLP report using your printer
The balance GLP report can be printed using a printer connected to the personal computer.
Receiving weighing data at a certain interval
The weighing data can be received at a certain interval and data characteristic with elapsed
time can be obtained.
Using the balance memory function
The data can be stored in the balance’s memory. Of the data stored, the weighing data and
calibration data can be transmitted to a personal computer at one time.
Using a personal computer as an external indicator
With the "RsKey" test mode function, a personal computer can be used as an external weight
indicator for the balance. (To do this, set the balance data output mode to stream mode.)

12-2. Acknowledge Code and Error Codes
When the "Serial interface function (5if)" parameter is set to "erCd 1", the balance outputs
code or error code to each command as follows:
(06h) Acknowledge in ASCII code.
When the balance receives a command to request data and can not process it, the balance
transmits an error code (EC, Exx).
When the balance receives a command to request data and can process it, the balance
outputs the data.
When the balance receives a command to control the balance and can not process it, the
balance transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the
balance transmits the acknowledge code.
Among commands to control the balance, the following transmit the acknowledge code
both when the balance receives the command and when the balance has
accomplished the command. If the command can not be processed properly, the
balance transmits an error code (EC, Exx). This error can be released using the CAL
command.
CAL command (Calibration command using internal mass)
ON command (Display ON command)
P command (Display ON/OFF command)
R command (RE-ZERO command)

46
R command
When a communication error has occurred due to external noise, or a parity error has
occurred due to transmission error, the balance transmits an error code. In this case, send
the command again.
xx is error code number.
12-3. Control Using CTS and RTS
Depending on the "Ct5" parameter of "Serial interface (5if)", the balance performs as follows:
Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the
CTS line HI. The balance outputs data regardless of the condition of the RTS line.
Ct5 1
The CTS line is kept Hi normally. When the balance can not receive the next command
(Example: while the balance is processing the last command), the balance sets the CTS line
to Lo. The balance confirms the level of the RTS line before outputting a set of data. If the
RTS level is Hi, the balance outputs data. If the RTS level is Lo, data is not output (The data
is canceled).
12-4. Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: "Data output (dout)" and "Serial
interface (5if)". Set each function as necessary.

13. Extended Function
The MC series balance has several extended functions equipped for special applications or to
troubleshoot when using the standard functions.
When the "Filter ( f1l)” is set to “ 0 “, extra items are available as shown below.
Class | Item and Parameter | Description | |
0 1 2 3 4 5 6 7 | f1-b Averaging range for the first moving average | Small Large When the fluctuation of a weight value is within the averaging range, the averaging operation starts to stabilize the displayed value. When the fluctuation of a weight value is small, for example, when weighing or filling a small amount of sample, the averaging is always performed and the response rate maybe slow. Under such a condition, change the parameter. Refer to “Averaging range ( f1-b ) and averaging time ( f1-t )” | erfnc Extended function |
0 1 2 3 4 5 6 7 8 | No averaging 0.5 second 1.0 second 1.5 seconds 2.0 seconds 2.5 seconds 3.2 seconds 4.8 seconds 6.4 seconds When the fluctuation of a weight value is within the averaging range, the averaging operation starts. Once the duration of averaging operations reach the averaging time, moving averaging starts. This parameter sets the time to start moving averaging. Refer to “Averaging range ( f1-b ) and averaging time ( f1-t )” | f1-t Averaging time for the first moving average | |
0 1 2 3 4 5 6 | f2-b Averaging range for the second moving average | Small Large Refer to “Filter depending on differences in the amount to deliver powdery and liquid material”. | |
0 1 2 3 4 5 6 | No averaging 0.5 second 1.0 second 1.5 seconds 2.0 seconds 2.5 seconds 3.2 seconds | f2-t Averaging time for the second moving average |

48
13-1. Description of "Averaging range" and "Averaging time"
13-1-1. Averaging range ( f1-b ) and averaging time ( f1-t )
1. When the fluctuation of a weight value is beyond the range that is selected in " f1-b ", the
averaging operation is disabled and the display reflects the varying value.
2. Once the fluctuation becomes within the selected range, the averaging operation starts to
stabilize the weight value.
3. The process of averaging increases. When the selected time is reached, moving averaging will
be performed.
When a small amount of sample is weighed or is filled, the fluctuation of a weight value is too small
to be beyond the selected range and the averaging operation is not disabled. Consequently moving
averaging is always performed and it takes a longer time to reach the final weight value. Under such
a situation, change the setting of " f1-b " to a smaller range. But please note that the smaller the
range is, the more prone to external disturbance the value will become.

GX-04K | Comparator Output (Relay/ with a Buzzer) / RS-232C / Current Loop This option generates a relay output corresponding to HI , OK and LO in the display. Current loop and RS-232C can be used at the same time. For example, a personal computer and an AD-8121B printer can be used simultaneously. This option is installed in place of the standard RS-232C serial interface. |
GX-06K | Analog Voltage Output / Current Loop This option outputs a voltage of 0 to1V (or 0.2 to1V) depending on the displayed value. With this option, current loop can be used. For example, an AD-8121B printer can be used simultaneously using this option. This option is installed in place of the standard RS-232C serial interface. So, RS-232C is not available for use. |
GX-07K | Waterproof and Dustproof RS-232C Cable Length 5m, straight type, D-sub 9pin - D-sub 25pin. Only the 25pin connector of the balance side is a waterproof type. |

17. Terms/Index
17-1. Terms
Calibration Adjustment of the balance so that it can weigh accurately.
Calibration weight A weight used for calibration
Data number Numbers assigned sequentially when weighing data or unit weight is
stored.
Digit The minimum weighing value available. Used for the balance, one digit
is the smallest mass that can be displayed.
Environment Ambient conditions such as vibration, drafts, temperature, static
electricity and magnetic fields which affect the weighing operation.
External weight The weight that you have.
GLP Good Laboratory Practice.
Internal mass Built-in calibration weight
IP-65 IP code: Degree of protection provided by enclosures.
6: Dust-tight. No ingress of dust. 5: Protect against water jets.
Mode Balance operational function.
Output To output the weighing data using the RS-232C interface.
Range A combination of weighing range and resolution.
Repeatability Variation in measured values obtained when the same mass is placed
and removed repetitively. Usually expressed as a standard deviation.
Example: Standard deviation = 1 digit: This means that measured
values, obtained when the same sample is placed and removed
repetitively, fall within ±1 digit in the frequency of about 68%.
Re-zero To set the display to zero.
Sensitivity drift An affect that a change in temperature causes to the weighing data.
Expressed as a temperature coefficient.
Example: Temperature coefficient = 2 ppm/°C : If a load is 8 kg and the
temperature changes by 10°C, the value displayed changes by the
following value.
0.0002%/°C x 10°C x 8 kg = 0.16 g
In this example, if the value displayed is 8000.00 g before temperature
changes, a temperature change of 10°C will make the value displayed
8000.16 g.
Smart range function The function allows weighing in the precision range, even if a heavy
tare is used.

60
Stable value The stable weight data, indicated by the illuminated stabilization
indicator.
Stabilization time Time required after a sample being placed, until the stabilization
indicator illuminates and the weighing data is displayed.
Store To save the weighing data, unit mass or calibration data using the data
memory function.
Tare To cancel the weight of a container which is not to be included in the
weighing data. Normally, refers to an operation of placing a container
and setting the display to zero.
Target weight An external weight used for calibration test
Zero point A weighing reference point. Usually refers to the value displayed when
nothing is on the weighing pan.
