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.

Shock

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.

Correction of the internal mass value

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)". Refer to "10. Function Table". Time and date can be added to the GLP report. If the time or date is not correct, adjust them. Refer to the GX-K series instruction manual "10-7. 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 "Data

memory (data)" to "3". Refer to the GX-K series instruction manual "12. Data Memory" for details.

The value of the internal mass may change due to aging, corrosion or other damage

caused by the operating environment. Check the internal mass periodically. Correct the internal mass value as necessary.

Caution on using an external weight

The accuracy of an external weight can influence the accuracy of weighing. Select an

appropriate weight as listed below:

Select a mass for calibration and calibration test from the following table.

Model Usable calibration weight Adjustable range

MC-10K 2 kg, 3 kg, 4 kg, 5 kg, 6 kg, 7 kg, 8 kg, 9 kg, 10 kg -0.150 g ~ +0.159 g

Display

This indicator means "In process of measuring calibration data".

Do not allow vibration or drafts to affect the balance while the indicator is displayed.

8-2. Automatic Self Calibration

Automatic self 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 in memory. Automatic self calibration functions even if the display is turned off (standby state). Refer to "9-1. Permit Or Inhibit" for the operation.

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.

11. ID Number And GLP Report

The ID number is used to identify the balance when Good Laboratory Practice (GLP) is used. The ID number is maintained in non-volatile memory even if the AC adapter is removed. The GLP output format is selected at "GLP output (info)" of the function table and can be

output to a personal computer or printer using the RS-232C serial interface. The GLP output format includes the balance manufacturer, model, serial number, ID

number, date, time and space for signature for weighing data, the weight used and results

for calibration or calibration test data. The balance can output the following reports for GLP.

"Calibration report" of the calibration, using the internal mass (Calibration due to changes in temperature and one-touch calibration.) "Calibration report" of the calibration, using an external weight. "Calibration test report" of the calibration test, using an external weight. "Title block" and "End block" for the weighing data.

Calibration and calibration test data can be stored in memory to output several reports at the

same time. Refer to the GX-K series instruction manual "12. Data Memory" for details. For details on confirming and setting the time and date, refer to the GX-K series instruction

Refer to "11-2. GLP Report" for print samples.

12-2-2. 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.)

13. Commands

13-1. Command List

Note A command has a terminator added, that is specified using "5if Crlf" of the

function table, and is sent to the balance.

Commands to query weighing data

C Cancels the S or SIR command. Q Requests the weighing data immediately. S Requests the weighing data when stabilized. SI Requests the weighing data immediately. SIR Requests the weighing data continuously.

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.

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.

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.

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 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).

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.

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 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 averaging time

When the fluctuation of a weight value is within

(

f1-t

)”

(

f1-b

)

and

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 ( averaging time (

f1-t

)”

f1-b

) and

Refer to “Filter depending on differences in the amount to deliver powdery and liquid material”.

14-1.

Description of "Averaging range" and "Averaging time"

14-1-1. 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.

14-1-2. 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 ).

In normal use, the balance can be cleaned with water. But, keep the following

precautions so that dust and water do not invade the balance. Do not direct water pressure at the bottom of the balance. Do not use powerful water jets. Do not submerge the balance in water.

Clean the balance with a lint free cloth that is moistened with warm water and a mild

detergent. Do not use organic solvents to clean the balance. Do not disassemble the balance. Contact the local A&D dealer if the balance needs

service or repair. Use the original packing material for transportation. While cleaning the balance and keeping it waterproof, connect a waterproof RS-232C

cable (GX-07K) or cover terminals of the RS-232C interface and AC adapter jack. Insure

that the underhook cover is in place. The value of the internal mass may change due to aging, corrosion or other damage

caused by the operating environment. Check the internal mass periodically. Correct the

internal mass value as necessary.

RS-232C interface Cover the terminal or connect the waterproof RS-232C cable (GX-07K) to keep waterproof and dustproof.

When the AC adaptor is not connected, cover the terminal.

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

Check the balance performance using the self-check function as described in "7. Weighing

Speed 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 the

center of the weighing pan. 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

Is the weighing table solid enough? Is the balance level? Refer to "3-1. Before Use". Is the operating environment free from vibration and drafts? Is there a strong electrical or magnetic noise source such as a motor near the balance?

Weighing method

Does the weighing pan touch the rim or anything? Is the weighing pan and pan support

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?

Sample and container

Has the sample absorbed or lost moisture due to the ambient conditions such as

temperature and humidity? Has the temperature of the container been allowed to equalize to the ambient temperature?

Refer to "3-2. During Use". Is the sample charged with static electricity? Refer to "3-2. During Use". Is the sample of magnetic material such as iron? Caution is required for weighing magnetic

materials. Refer to "3-2. During Use".

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.

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.
