Refer to “8. CALIBRATION”.
12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 thefollowing:

3-1 Before Use
 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. Duringcalibration using an internal mass, it resolves up to one digit lower
than the minimum weighing value. Therefore, be sure to place thebalance in a stable environment.
 The best operating temperature is about 20°C±2°C at 45-60%
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 which 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 itusing the bubble spirit level.
 If static electricity is a problem at the installation site, use theelectrostatic field meter and the static eliminator.
 Ensure a stable power source when using the AC adapter.

13

 Warm up the balance for at least 30 minutes. Plug in the AC
adapter as usual.
 Calibrate the balance periodically for accurate weighing.
 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 toallow 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
 Static charge may cause weighing errors. When theambient 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 (hereinafterreferred to as sample). Ground the balance and try thefollowing:
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.
 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 theunderhook on the bottom of the balance to suspend thematerial away from the influence of the magnet.
 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.
 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 thebalance weighing capacity. Place a 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.
 Take into consideration the affect of air buoyancy on a sample when more accuracy is required.
 Keep the balance interior free of dust and foreign materials.

14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 orrepair.
 Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that ismoistened with warm water and a mild detergent.
 Protect the internal parts of the balance from liquid spills and excessive dust.

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 ison (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.

6. WEIGHING
6-1 Selecting a Weighing Unit (Mode)
Press the MODE key to select a unit or mode for weighing.
The unit “g” (gram) was set at the factory.
To use other units, select and store units and displaying order in the function setting of “ Unit ”.
For details on weighing unit storing procedure, refer to the GX series instruction manual “5-2 Storing
Units”.

6-2 Basic Weighing
For more stable weighing
 To reduce the influence of drafts and vibration, set the following function settings as below.
“Condition ( Cond )” of “Environment, Display ( ba5fnc )” to “Slow ( 2 )”“Filter ( f1l )” of ““Environment, Display ( ba5fnc )” to “Used (1 )”Function settings
Refer to “10. FUNCTION TABLE” on page 32 to check or change the function settings.

Display□ For stable weighing
When weighing values are unstable even with the functions set to those more resistant to external
disturbances (“Cond” to “1” and “f1l” to “1” ), use the AD-1672 Tabletop Breeze Break to protect thebalance from breezes.

Usage example: AD-1672 Tabletop Breeze Break and MC-1000 Balance
19When using as a mass comparator
 To avoid eccentric loading errors, place the sample in the center of the weighing pan.
As an option, auto-centering pans are available: AX-MC1000PAN for the MC-1000 and
AX-MC6100PAN for the MC-6100.
Using an AD-8922A remote controller, which is sold separately, the balance can be controlled
remotely by the AD-8922A key operations in the same way as when the CAL or
RE-ZERO key of the balance is pressed. For the connection procedure between the balance
and the AD-8922A, refer to the AD-8922A instruction manual.
 Take measures against causes of weighing error at the installation site, such as changes intemperature, atmospheric pressure, drafts, vibration and static electricity. Perform weighing
operations in a stable environment.
 The table below lists the weight class and recommended measuring range for each model of the
MC series. The measuring range is determined so that the balance repeatability is to be less than
one third of the maximum permissible error for each weight class.

When building into a system When a special weighing pan is to be designed, the weight of the pan and the material to beweighed should not exceed the weighing capacity of the balance.
To reduce influences of static electricity and magnetism, use materials other than resin andmagnetic material such as iron.
 There is a function available to maintain the previous weight value in non-volatile memory, even if
the AC adapter is removed.
When “Zero upon power-on ( p-tr )” of “Environment, Display ( ba5fnc )” is set to “ 1 ”, theprevious weight value is displayed upon power-on.
For details, refer to “Zero upon power-on” on page 37.
 There is a function available to perform span calibration only, when performing calibration with atare on the weighing pan.
When “Span calibration ( 5pn )” of “Environment, Display ( ba5fnc )” is set to “ 1 ”, spancalibration using the internal mass is performed, with a tare on the weighing pan.
For details, refer to “Span calibration” on page 37.
 To set a higher response rate or to batch-weigh small amounts of material, such as a powdery
material, refer to “15. EXTENDED FUNCTION”.

7. RESPONSE ADJUSTMENT / SELF CHECK FUNCTION
This function detects the influence on weighing that is caused by drafts and/or vibration at the place
where the balance is installed and sets the response characteristic automatically. When this function is
selected, the balance self-checks the performance at the same time.
Two modes of response adjustment are available: automatic and manual.

Terms
The following terms are defined as follows:
Internal mass
= Built-in calibration weight
External weight= A weight that you have. Referred to as a calibration weight when used for calibration.
Calibration weight = A weight used for calibration
Target weight= An external weight used for calibration test

Caution Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:• the balance is installed for the first time.
• the balance has been moved.
• the ambient environment has changed.
 Do not allow vibration or drafts to affect the balance during calibration.
 To output the data for GLP using the RS-232C interface, set “GLP output ( info )” of “Data output( dout )”. For details, refer to “10. FUNCTION TABLE”. Time and date are added to the GLP
report. If the time or date is not correct, adjust them. For details, refer to the GX series instruction
manual, “10-9 Clock and Calendar Function”.
 Calibration test is available only when “GLP output ( info )” of “Data output ( dout )” is set to “1 ”
or “ 2 ”.
 The calibration and calibration test data can be stored in memory. To store them, set “Datamemory ( data )” to “ 3 ”. For details, refer to the GX series instruction manual, “12. DATAMEMORY”.

Caution on using an external weight The accuracy of an external weight can influence the accuracy of weighing. Select an appropriate

8-2 Automatic Self Calibration (Calibration due to changes in temperature)
This function automatically calibrates the balance when the balance detects an ambient temperature change. If
GLP output is selected in the function table, the balance outputs the calibration report or stores the data inmemory. Automatic self calibration functions even if the display is turned off (standby state). ,CautionIf something is on the weighing pan, the balance judges that it is in use and does not perform
automatic self calibration. To maintain the calibrated state, keep the weighing pan clear while
not in use.
The displays shown below are related to the automatic self calibration.
Indicates that the balance detects a change in ambient temperature andautomatic self calibration will start. If the balance is not used for a few minuteswith this indicator blinking, the balance performs automatic self calibration. The
blinking duration depends on the environment.
Indicates that the balance is measuring calibration data. Do not allow vibration
or drafts to affect the balance while this indicator is displayed. After calibration,
the balance returns to indicate the previous display.
Note
The balance can be used while the indicator blinks. But, it is recommended that to maintain theaccuracy, stop using the balance and confirm that there is nothing on the pan and allow thebalance to perform self calibration.

8-3 Calibration Using the Internal mass (One-touch calibration)
This function calibrates the balance using the internal mass. The only operation required is to press the
CAL key

Operation
1 Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on theweighing pan.
2 Press the CAL key.
3 The balance displays Calin and performs calibration using the internal mass. Do not allow
vibration or drafts to affect the balance.
4 The balance displays end after calibration. If the “GLP output (info )” parameter of thefunction table is set to “1 ” or “ 2 ”, the balance displays glp and outputs the “Calibration
Report” using the RS-232C interface or stores the data in memory. For details on the calibration
report format, refer to “11-2 GLP Report”.
5 The balance will automatically return to the weighing mode after calibration.

About the internal mass
The value of the internal mass may change due to corrosion or other damage caused by theoperating environment, or due to aging. Check the internal mass periodically. Correct the internalmass value as necessary. For details, refer to “8-6 Correcting the Internal Mass Value”.
To maintain the weighing accuracy, perform the calibration using an external weight periodically, as

10-4 Description of the Class “Environment, Display”
Condition ( Cond )Cond 0Cond 2This 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 aweight 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 0This parameter is for sensitive response of the stabilization indicator. Used forexact weighing.

5t-b 2This parameter ignores slight fluctuation of a weight value. Used to prevent aweight value from drifting due to vibration or drafts.
NoteWith “Hold function ( Hold )” set to “ON (1 )”, this item is used to set thestabilization 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 thematerial 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 thevalue in the table below, calibration using the internal mass is possible.

13-2 Connection to a Computer
The MC series balance is of the DCE type (Data Communication Equipment), which can beconnected 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).

13-3 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT can be used totransmit the weighing data to the personal computer.
The current version of the WinCT can be downloaded from the A&D website. Check for applicable
Windows versions when downloading the software.
For details on WinCT, refer to the WinCT instruction manual which is available on the A&D website.
The WinCT has two communication methods: “RsCom” and “RsKey”

RsCom Can transmit commands to control the balance.
 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 printerconnected to the personal computer.
 When several ports of a personal computer have balances connected, the personal computer cancommunicate with each balance simultaneously.
 Can share a personal computer with other application software.
 Can receive the balance GLP report.

RsKey Can transmit the weighing data output from the balance directly to other application software suchas Microsoft Excel.
 Can be used with most application software.
 Can receive the balance GLP report.
Note
Windows and Excel are registered trademarks of 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 thedata to obtain total, average, standard deviation, maximum and minimum value, and display themin 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 weighingdata” to the balance and controls the balance.
52

3 Printing the balance GLP report using your printerThe 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 thebalance’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 weightindicator for the balance. (To do this, set the balance data output mode to stream mode.)5314. COMMANDS

14-2 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.

 When the balance receives a command to request data and can not process it, the balancetransmits 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 balancetransmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the balancetransmits the acknowledge code.
Among commands to control the balance, the following transmit the acknowledge code bothwhen 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.

14-3 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 thebalance is processing last command), the balance sets the CTS line to Lo. The balance confirms thelevel 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).

14-4 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.

5615. EXTENDED FUNCTION
The MC series balance has several extended functions equipped for special applications or totroubleshoot when using the standard functions.
When the "Filter ( f1l)” is set to “ 0 “, extra items are available as shown below.

Class

Item and Parameter0

Description
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 ofsample, the averaging operation is always
performed and the response rate may be
slow. Under such a condition, change theparameter.

15-1 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 ", theaveraging operation is disabled and the display reflects the varying value.
2. Once the fluctuation becomes within the selected range, the averaging operation starts tostabilize 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 sucha situation, change the setting of " f1-b " to a smaller range. But please note that the smaller therange is, the more prone to external disturbance the value will become.

17. TROUBLESHOOTING
17-1 Checking the Balance Performance and Environment
The balance is a precision instrument. When the operating environment or the operating method isinadequate, correct weighing can not be performed. Place a sample on the pan and remove it, andrepeat 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 Check the balance performance using the self-check function as described in “7-1 Automatic
Response Adjustment / Self Check Function”.
An error display appears when a malfunction is found.
 Check the balance repeatability using an external weight. Be sure to place the weight in thecenter of the weighing pan.
 Check the balance repeatability, linearity and calibrated value using external weights with aknown value.

Checking that the operating environment or weighing method is proper
Operating environment
 Is the weighing table solid enough (especially for the balance with a minimum weighing value of
0.0001 g)?
 Is the balance level? Refer to “3-1 Before Use”.
 Is the operating environment free from vibration and drafts? Has the breeze break been installed?
 Is there a strong electrical or magnetic noise source such as a motor near the balance?
Weighing method Does the weighing pan touch the breeze ring or anything? Is the weighing pan installed correctly?
 Is the RE-ZERO key pressed before placing a sample on the weighing pan?
 Is the sample placed in the center of the weighing pan?
 Has the balance been calibrated using the internal mass (one-touch calibration)?
 Has the balance been warmed up for 30 minutes before weighing?
60

Sample and container
 Has the sample absorbed or lost moisture due to the ambient conditions such as temperature andhumidity?
 Has the temperature of the container been allowed to equalize to the ambient temperature? Referto “3-2 During Use”.
 Is the sample charged with static electricity? Refer to “3-2 During Use”.
Static electricity is generated when the relative humidity is low.
