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

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.

If GLP output is selected in the function table, the balance outputs the calibration report or stores the data in memory. Automatic self calibration functions even if the display is turned off (standby state). ,
Caution
If 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 and automatic self calibration will start. If the balance is not used for a few minutes with 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 the accuracy, stop using the balance and confirm that there is nothing on the pan and allow the balance to perform self calibration.

10-4 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.

13-2 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).  
13-3 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. z Can display or store the data using a text file
format. Can also print the data using a printer  
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.  
48

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.)

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.

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.

CAL command (Calibration command)

ON command (Display ON command)

P command (Display ON/OFF command)

R command (RE-ZERO command)

z 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.

51

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 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).  
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.  
52

15\. EXTENDED FUNCTION

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 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”.

53

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 “, 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.  
54

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 ).  
55

16\. 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.  
17\. TROUBLESHOOTING  
17-1 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
“7-1 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?  
56

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. z Is the
sample of magnetic material such as iron? Caution is required for weighing
magnetic  
materials. Refer to “3-2 During Use”.

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

About the MC series balance function settings

Factory settings have been changed for stable weighing  
The factory settings described on page 31 of the MC series instruction manual
have been changed.  
The MC series are high resolution balances. Therefore, external disturbances
such as breezes or vibrations may cause unstable weighing values. For stable
weighing, the factory settings of the following functions have been changed to
those more resistant to external disturbances, as shown below.
