2-3 Installing the Balance
Install the balance as follows:
1. Refer to “3-1 Before Use” for installing the balance. Place the balance on a solid weighing
table.
2. Assemble the balance as shown in “2. UNPACKING THE BALANCE”.
3. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level.
4. Confirm that the adapter type is correct for the local voltage and power receptacle type.
5. Connect the AC adapter to the balance. Warm up the balance for at least 30 minutes with
nothing on the weighing pan.
3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing data, note the
following:
3-1 Before Use
z The MC series is a high-precision balance with a resolution of
1/10000000. It is prone to changes in temperature and pressure, static electricity, drafts and vibration of the installation site. During calibration using an internal mass, it resolves up to one digit lower than the minimum weighing value. Therefore, be sure to place the balance in a stable environment.
z The best operating temperature is about 20°C±2°C at 45-60%
relative humidity.
z Install the balance where it is not exposed to direct sunlight and
it is not affected by heaters or air conditioners.
z Install the balance where it is free of dust.
z Install the balance away from equipment which produces
magnetic fields.
z 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.
z The weighing table should be solid and free from vibration,
drafts and as level as possible.
z Level the balance by adjusting the leveling feet and confirm it
using the bubble spirit level.
z If static electricity is a problem at the installation site, use the
electrostatic field meter and the static eliminator.
z Ensure a stable power source when using the AC adapter.
10
z Warm up the balance for at least 30 minutes. Plug in the AC
adapter as usual.
z Calibrate the balance periodically for accurate weighing.
z Before using the balance for the first time or after having moved
it to another location, warm up the balance for six hours or more to allow the balance to reach equilibrium with the room temperature, and then calibrate the balance.
Caution
Do not install the balance where flammable or corrosive gas is present.
3-2 During Use
z Static charge may cause weighing errors. When the
ambient humidity is less than 45% RH, insulators such as
plastic or glass are prone to static electricity. Discharge
static electricity from the material to be weighed
(hereinafter referred to as sample). Ground the balance
and try the following:
Eliminate the static electricity by using an optional
static eliminator, AD-1683, Or try to keep the ambient humidity above 45%RH. Or use a metal shield case. Or wipe a charged plastic sample with the wet cloth.
z 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.
z Cancel the temperature difference between a sample, tare 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.
z Make each weighing gently and quickly to avoid errors due to changes in the environmental
conditions.
z Do not drop things upon the weighing pan, or place a sample on the pan that is beyond the
balance weighing capacity. Place a sample in the center of the weighing pan.
z Do not use a sharp instrument such as a pencil to press the keys. Use your finger only.
z Press the RE-ZERO key before each weighing to prevent possible errors.
z Take into consideration the affect of air buoyancy on a sample when more accuracy is
required.
z Keep the balance interior free of dust and foreign materials.
11
3-3 After Use
z Avoid mechanical shock to the balance.
z Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or
repair.
z 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.
z Protect the internal parts of the balance from liquid spills and excessive dust.
3-4 Power Supply
z 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.
z When the AC adapter is connected, the balance is in the standby mode if the standby indicator
is on (refer to “4. DISPLAY SYMBOLS AND KEY OPERATION”). This is a normal state and does not harm the balance. For accurate weighing, warm up the balance for at least 30 minutes before use.

7-6 Correcting the Internal Mass Value
The MC series balance can correct the internal mass value within the range shown below. This function corrects the internal mass value to conform to an external weight. The corrected mass value is maintained in non-volatile memory even if the AC adapter is removed.
The internal mass value is corrected as follows:
Model Correction reference value Correction range
MC-1000 500.0000 g ±0.020 g
MC-6100 2000.000 g ±0.20 g
Example: Using the MC-6100
Use the same weight
4 kg
Correct the internal mass by +0.030 g in 2 kg. Calibrate the balance with the corrected internal mass.
Operation

9-4 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.
Cond 2 This parameter is for stable weighing with slow response. Used to prevent a
weight value from drifting due to vibration or drafts. After setting, the balance displays SLOW.
Notes
In automatic response adjustment, the response rate 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 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.

12-2 Connection to a Computer
The MC series 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).
12-3 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the provided WinCT can be used to transmit the weighing data to the personal computer. The WinCT has two communication methods: “RsCom” and “RsKey”. For details on WinCT, refer to the WinCT instruction manual. The current version of the WinCT can be downloaded from the A&D website.
RsCom
z Can transmit commands to control the balance.
z Can perform bi-directional communication between the balance and a personal computer
using the RS-232C interface.
Can display or store the data using a text file format. Can also print the data using a printer
z
connected to the personal computer.
z When several ports of a personal computer have balances connected, the personal computer
can communicate with each balance simultaneously.
z Can share a personal computer with other application software.
z Can receive the balance GLP report.
RsKey
z Can transmit the weighing data output from the balance directly to other application software
such as Microsoft Excel.
z Can be used with most application software.
z Can receive the balance GLP report.
Note Windows and Excel are the registered trademarks of the Microsoft Corporation.
Using the WinCT software, the balance can do the following:
1 Analyzing the weighing data and the statistics input by “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.
2 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.
46
3 Printing the balance GLP report using your printer The balance GLP report can be printed using a printer connected to the personal computer.
4 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.
5 Using the MC series balance memory function The weighing data, instead of outputting it immediately to an external device, can be stored in
the balance’s memory. Later, all of the weighing data stored can be output to a personal computer at one time.
6 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.)

13-2 Acknowledge Code and Error Codes
When the “Serial interface function ( 5if )” parameter is set to “ erCd 1 ”, the balance outputs <AK>
code or error code to each command as follows:
<AK> (06h) Acknowledge in ASCII code.
z 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.
z 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.

13-3 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 condition of the RTS line.
Ct5 1
The CTS line is kept Hi normally. When the balance can not receive the next command (e.g. while the balance is processing 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).
13-4 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.
50
14. EXTENDED FUNCTION
The MC series balance has several extended functions equipped for special applications or to troubleshoot when using the standard functions.

When the fluctuation of a weight value is within the averaging range, the averaging operation starts to stabilize the value. When the fluctuation is small, for example, when weighing or filling a small amount of sample, the averaging operation is always performed and the response rate may be slow. Under such a condition, change the parameter. Refer to “Averaging range ( f1-b ) and averaging time ( f1-t )”
When the fluctuation of a weight value is within the averaging range, the averaging operation starts. Once the duration of averaging operations reaches 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 )”
Refer to “Filter depending on differences in the amount to deliver powdery and liquid material”.
51
14-1 Description of "Averaging range" and "Averaging time"
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.
52
Filter depending on differences in the amount to deliver powdery and liquid
material
z When the weight value is not stable even without load fluctuations
Increase the averaging range for the first moving average parameter ( f1-b ). Increase the averaging time for the first moving average parameter ( f1-t ). Strengthen the digital filter. (Increase the function setting “Condition ( Cond )” parameter.)
z When response is slow during full and medium flow
Decrease the averaging range for the first moving average parameter ( f1-b ). Weaken the digital filter. (Decrease the function setting “Condition ( Cond )” parameter.)
z When response is slow during dribble flow
Decrease the averaging time for the first moving average parameter (f1-t). Weaken the digital filter. (Decrease the function setting “Condition ( Cond )” parameter.
z To increase stability without load fluctuations
Increase the averaging range for the second moving average parameter ( f2-b ). Increase the averaging time for the second moving average parameter ( f2-t ).
53
15. MAINTENANCE
z 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.
z Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair.
z Use the original packing material for transportation.
16. TROUBLESHOOTING
16-1 Checking the Balance Performance and Environment
The balance is a precision instrument. When the operating environment or the operating method is
inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and
repeat this several times. If the balance seems to have a problem with repeatability or to perform
improperly, check as described below. If improper performance persists after checking, contact the
local A&D dealer for repair.
Checking that the balance performs properly
z Check the balance performance using the self-check function as described in “6-1 Automatic
Response Adjustment / Self Check Function”.
An error display appears when a malfunction is found.
z Check the balance repeatability using an external weight. Be sure to place the weight in the
center of the weighing pan.
z Check the balance repeatability, linearity and calibrated value using external weights with a
known value.
Checking that the operating environment or weighing method is proper
Operating environment
z Is the weighing table solid enough (especially for the balance with a minimum weighing value
of 0.0001 g)?
z Is the balance level? Refer to “3-1 Before Use”.
z Is the operating environment free from vibration and drafts? Has the breeze break been installed?
z Is there a strong electrical or magnetic noise source such as a motor near the balance?
Weighing method
z Does the weighing pan touch the breeze ring or anything? Is the weighing pan installed
correctly?
z Is the RE-ZERO key pressed before placing a sample on the weighing pan?
z Is the sample placed in the center of the weighing pan?
z Has the balance been calibrated using the internal mass (one-touch calibration)?
z Has the balance been warmed up for 30 minutes before weighing?
54
Sample and container
z Has the sample absorbed or lost moisture due to the ambient conditions such as temperature
and humidity?
z Has the temperature of the container been allowed to equalize to the ambient temperature?
Refer to “3-2 During Use”.
z Is the sample charged with static electricity? Refer to “3-2 During Use”.
Static electricity is generated when the relative humidity is low.

Terms
Stable value The weight data when the stabilization indicator appears. Environment Ambient conditions such as vibration, drafts, temperature, static electricity and
magnetic fields which affect the weighing operation.
Store To save the weighing data, unit mass or calibration data using the data memory
function.
Calibration Adjustment of the balance so that it can weigh accurately. Output To output the weighing data using the RS-232C interface. Zero point A weighing reference point or the zero display. Usually refers to the value
displayed when nothing is on the weighing pan.
Data number Numbers assigned sequentially when weighing data or unit weight is stored. Digit Unit of digital resolution. Used for the balance, a unit of minimum weighing value. Tare To cancel the weight of a container which is not included in the weighing data. Mode Balance operational function. Re-zero To set the display to zero. GLP Good Laboratory Practice. Repeatability Variation in measured values obtained when the same weight is placed and
removed repetitively. Usually expressed as a standard deviation.
e.g. Standard deviation=1 digit: This means that measured values fall within ±1
digit in the frequency of about 68%.
Stabilization time Time required after a sample being placed, until the stabilization indicator
illuminates and the weighing data is displayed.
Sensitivity drift An affect that a change in temperature causes to the weighing data. Expressed
as temperature coefficient.
e.g. Temperature coefficient = 2 ppm/°C : If a load is 500 g and the temperature
changes by 10°C, the value displayed changes by the following value.
0.0002%/°C x 10°C x 500 g = 10 mg
