This manual describes how the GX-M/GF-M series balance works and how to get the most out of it interms of performance. Read this manual thoroughly before using the balance and keep it at hand for
future reference.
Depending on the software version of your balance, there are cases that behave differently.
For confirmation of the software version of the balance, refer to "25. How to Check the Software
Version of the Balance".

1-1 Features
The balance has a self-check function that inspects the balance itself using electronicallycontrolled load (ECL) and evaluates performance. Read this manual thoroughly before using thebalance and keep it at hand for future reference.
The balance can detect impact applied to its mass sensor and display the level of that impact.
ISD (Impact Shock Detection).
Continuous change of the balance can be calculated as flow rate, displayed and output.
FRD :(Flow Rate Display).
The balance is equipped with a data memory function, which can record weighing value, sensitivity
adjustment result, and multiple unit mass (mass per sample in counting mode) (Up to 200 items
are stored for weighing value).
The GX-M series has automatic sensitivity adjustment using the internal mass, adapting totemperature changes, setting time and interval time.
When performing the sensitivity adjustment/calibration test, etc. for the balance, the output
corresponding to GLP/GMP, etc. can be output. Using a printer (sold separately), it ispossible to record the sensitivity adjustment/calibration test results.
GLP: Good Laboratory Practice. Standards for implementing safety tests for drugs andmedicines.
GMP: Good Manufacturing Practice. Rules for manufacturing and quality control.
A built-in clock and calendar that can add the time and date to the output data.

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 one million counts. Therefore, there are tendencies
to be influenced by temperature change, air pressure change, vibration and drafts where the balance isplaced.
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.
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 sensitivity
adjustment before use.
The balance’s dustproof and waterproof rating is equivalent to IP65, and its second digit, “5”, corresponds
to "having no harmful influence by receiving direct jet of water". Washing with strong water pressure,washing with the weighing pan removed, or submersion in water may cause water to enter the balance,
resulting in a malfunction.
When washing with warm water, condensation may occur and harm the components. Be careful not toallow water vapor to get inside.
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 (AX-KO2737-500EX)", when using the balance.
Use the waterproof option cable AX-KO2737-500EX, when the RS-232C interface is used with
IP-65. AX-KO2466-200, a standard RS-232C cable, is not waterproof or dustproof.
Confirm that the weighing pan does not touch to rim.
Errors due to moving the weighing system:
The performance of this product is guaranteed when it is used in a stationary condition. If thebalance is incorporated into a system that moves the balance, you must carefully perform checks inadvance while paying attention to the following.
If the balance is moved, it may be damaged by impact shocks. In addition, the weighing
value will be unstable immediately after the balance is moved. Avoid sudden movements,
stops, or impact shocks, and provide a sufficient waiting time for the weighing value tostabilize when acquiring weighing data.
10

The moving device should have a structure where the balance can be kept level. If thelevel is shifted, the zero point or sensitivity will be shifted, so perform re-zero operation or
sensitivity adjustment.
In order to avoid the influence of vibration, the moving platform should have a structure
not easily susceptible to vibration by means such as reducing the play of moving parts.
Do not install the balance where flammable or corrosive gas is present.
Please use the dedicated AC adapter specified for the balance.
If you use the wrong AC adapter, the balance and other equipment may not operate properly.

3-2 During Use
Discharge static electricity from the weighing material. When weighing
sample (plastics, insulator, etc.) could have a static charge, theweighing value is influenced. Ground the balance by using the
grounding terminal. For the location of the grounding terminal, refer to“2-1 Installing the Balance”.
Eliminate the static electricity by AD-1683A as an accessory.
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.

Material case
ChargedsampleThis 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.

Magnetic
material

Eliminate any temperature difference between the sample and theenvironment. 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 panthat is beyond the balance weighing capacity. Place the sample in thecenter of the weighing pan.
Do not use a sharp instrument such as a pencil to press the keys. Use yourfinger 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 moreaccuracy is required.
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.

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 moistenedwith warm water and a mild detergent.
Do not allow the balance to be immersed in water. Even though the balance complies with IP code, thebalance 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 splashingwith water.

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 sensitivity adjustment 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. 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.

5. Weighing Units
5-1 Units
With the GX-M /GF-M series balance, the following weighing units and weighing modes are available:(To use this mode, it must be stored in the function table as descried on
page 48. For details about this mode, refer to “20. Density Measurement”.)
To select this mode, press the MODE key until the processing indicator
blinks with the unit “g” displayed. “DS” appears only when the density value
is displayed.)(No unit displayed. For details, refer to “19. Programmable-Unit”.)
A unit or mode can be selected and stored in the function table as described on page 48. If a weighing
mode (or unit of weight) has been turned off, that mode or unit will be missing in the sequence. Taelhas four varieties, one of which can be selected and installed at the factory.
To select a unit or mode for weighing, press the MODE key.

About the operation when the power is turned on
The balance will decide the reference zero-point when the power is turned on with the ON:OFF key.
Depending on the load condition at that time, the balance will automatically judge whether to performzeroing (power on zero) or tare subtraction operation. The condition for determining power on zero isused is "power on zero range" by making the zero point during sensitivity adjustment a standard. Whenpower on zero range is exceeded, the tare subtraction operation is performed by making the zero point
during sensitivity adjustment a standard.
About re-zero operation
By pressing the RE-ZERO key, the display can be changed to zero.
Re-zero with the RE-ZERO key will automatically determine whether zero or tare operation is
performed. The condition for determining zero is used is "zero range" by making the zero point (poweron zero) at the start of weighing a standard. When zero range is exceeded, the tare subtraction
operation is performed by making power on zero a standard.
About measurement range
For the balance, the range that can be weighed is determined by model.
The total amount (net amount + tare quantity) up to the maximum display of each model is displayed,
and when the maximum display is exceeded, E is displayed to indicate that the weighing range is
exceeded. When in excess in negative, -E is displayed.

6-2 Counting Mode (PCS)This is the mode to determine the number of objects in a sample based on the standard sample unitmass. Unit mass means the mass of one sample. The smaller the variables in each sample unit massis, the more accurate the counting will be. This series balance is equipped with the Automatic Counting
Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note
For counting, use samples that have a unit mass at least ten times greater than that of thereadability in grams.
If the sample unit mass variable is too large, it may cause a counting error.
To improve the counting performance, use the ACAI function frequently or divide thesamples into several groups and count each group.

9. Counting accuracy is improved when the processing indicator turns off.
10. Each time the above operation is performed, a more accurate unit mass will be obtained.
There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try
to add the same number of samples as displayed.
11. Remove all the samples used in ACAI and proceed with the counting operation using theimproved unit mass.

7. Impact Shock Detection Function (ISD)The GX-M / GF-M series has a function to detect impact to the mass sensor section and to display the
impact level.
By lowering the impact level at the time of loading, it is possible not only to alleviate variation in theweighing value but also to reduce the risk of failure of the mass sensor section.
Especially when incorporating the balance in a production line, etc. and weighing by means such as an
automated system, impact to the sensor may be applied greater than expected.
When designing automatic systems and the like, it is recommended that you minimize the impact levelas much as possible while checking the shock indicator.
Impact level display is from level 0 to level 4, 5 levels.

You can turn off the impact level display by setting “(Impact shock detection)” to “(off)” in“(Environment/Display)” in “11. Function Table”.
Even if the impact shock detection function is turned off, a record is kept in the balance when there is ashock impact.
Note
Impact on the weighing sensor may be applied to the weighing pan at time of loading, or it
may be applied from the table on which the balance is installed.
The impact shock detection function (ISD) also works for impact applied from the table.

7-1 Recording Impact History
Impacts of impact level 3 or higher are stored on the balance with data and time included (maximum
50 data instances).
When the password lock function is on (or), the login user information is added when
outputting the impact history.

Note
If 50 data instances are exceeded, the data with the lowest impact level is overwritten.
The stored impact history cannot be deleted.
Impact data where the balance is not energized (during transport, etc.) is not stored.

8-2 Self-Check-Function/Automatic Setting of Minimum WeightThe self-check function can easily check about whether proper performances are satisfied for thebalance by checking and displaying repeatability in addition to malfunction check. In addition, it canalso display and store minimum weight (reference value) using data of the repeatability.
Note
The USP (Pharmacopoeia of the United States of America) defines minimum measured
value as the repeatability measurement using a weight. Please note that repeatability andminimum measured value calculated by the ECL (Electronically Controlled Load) should be
used as a reference value only.
Refer to “Balance information” on the A&D web site (https://www.aandd.co.jp/) for detailsof the minimum weight.

9. Sensitivity Adjustment/Calibration Test
Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes. It is necessary to perform sensitivity adjustment with the weight in order tokeep the weighing values from changing even if gravity or the environment changes.
It is recommended that you calibrate if the balance is installed for the first time or relocated, or when
the weighing values change significantly in daily inspection, etc.
Adjustment means to adjust the weighing value of the balance using the reference weight or internal
mass. Sensitivity adjustment is to weigh with the reference weight and compare how much the result
deviates from the reference value. (Adjustment is not performed in sensitivity adjustment.)

Sensitivity adjustment
Automatic sensitivity adjustment ......................... Automatically adjust the balance using the internalmass depending on the temperature change of theoperating environment or the set time and interval
time. (GX-M series)
Sensitivity adjustment using the internal mass ........ Using the internal mass, adjust the balance with asingle touch.
Sensitivity adjustment using an external weight ...... Using an external mass, adjust the balance with an
external mass.

Calibration test

Calibration test with an external weight ············ Output the result of checking the accuracy ofweighing using your own weight.
* No adjustment is made.
Note
Do not allow vibration or drafts to affect the balance during sensitivity adjustment.
To output the data for GLP/GMP using the RS-232C interface, set "GLP/GMP output ()" of"Data output ()". Refer to "11. Function Table". The time and date can be added to the
GLP/GMP report. If the time or date is not correct, adjust them. Refer to "11-4 Clock andCalendar Function".
The sensitivity adjustment and calibration test data can be stored in memory. To store them, set"Data memory ()".
Caution when using your external weight
The accuracy of the weight used in sensitivity adjustment affects the accuracy of the balance
after sensitivity adjustment.
Select the mass to be used for sensitivity adjustment and calibration tests from the tablebelow.

DisplayThis indicator means "In process of measuring sensitivity adjustment data".
Do not allow vibration or drafts to affect the balance while the indicator isdisplayed.

9-1 Automatic Sensitivity Adjustment for the GX-M SeriesThis function automatically calibrates the balance using the internal weight due to a temperaturechange in the ambient environment, time set or interval time. It can function even when the balance’s
display is in off. If GLP output in function table is selected, the balance outputs the sensitivity
adjustment report or store the data in memory after sensitivity adjustment.
In the automatic sensitivity adjustment mode, either the temperature change (), the setting time(), or the interval time () can be set with the function setting.
For the setting time, the three function setting of,andcan be set.
Interval time can be set from 0.5h to 24h with function setting.
CautionIf something is on the weighing pan, the balance judges that it is in use and does not perform
automatic sensitivity adjustment.
The criteria that the balance judges is in use are as follows.
0.01 g modelMore than 20 g

0.1 g modelMore than 200 g

To maintain the calibrated state, keep the weighing pan clear while not in use.
Indicates that the balance detects a change in ambient temperature andautomatic sensitivity adjustment will start. If the balance is not used for a
few minutes with this indicator ( ) blinking, the balance performs automatic
sensitivity adjustment. The blinking duration depends on the environment.
Indicates that the balance is measuring sensitivity adjustment data. Do notallow vibration or drafts to affect the balance while this indicator is displayed.
After sensitivity adjustment, 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 sensitivity adjustment.
Depending on the setting of "10. Function Switch and Initialization", "change prohibited" or"changeable (usable)" can be selected.

11-3 Description of the Class "Environment, Display"
Condition ()
This parameter is for sensitive response to the fluctuation of a mass value. Used for
powder target mass, 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 mass value
from drifting due to vibration or drafts. After setting, the balance displays SLOW .

Stability band width ()

This item controls the width to regard a mass value as a stable value. When the fluctuation per second isless than the parameter, the balance displays the stabilization indicator and outputs or stores the data byfunction setting (,, etc.) The parameter influences the "Auto print mode". Also, the readability
being displayed is 1 d.
Ex. If 0.1 g display is selected by pressing the SAMPLE key on the GX-10002M, 0.1 g is 1 d.
This parameter is used for sensitive response of the stabilization indicator. Used forexact weighing.
This parameter ignores slight fluctuations of a mass value. Used to prevent a mass
value from drifting due to vibration or drafts

Hold function () (Animal weighing mode)This function is used to weigh a moving object such as an animal. When the weighing data is over theweighing range from zero and the display fluctuation is within the stabilization range for a fixed periodof averaging time, the processing indicator illuminates and the balance displays the average weight of
the animal. When the animal or sample is removed from the weighing pan, the display returns to zeroautomatically. This function is available only when the hold function parameter is set to " " (theanimal mode indicator HOLD illuminates) and any weighing unit other than the counting mode isselected. The stabilization range and averaging time are set in "Condition ()" and "Stability band
width ()".

Zero tracking ()

This function tracks zero point drift caused by changes in the environment and stabilizes the zero point.
When the weighing data is only a few d, turn the function off for accurate weighing.
The tracking function is not used. Used for weighing a very light sample.
The normal tracking function is used. (±1 d / 1 second)

Display refresh rate ()

The periodic time to refresh the display. This parameter influences "Baud rate", "Data output pause" andthe data output rate of "Stream mode".

Decimal point ()

The decimal point format can be selected.

Auto display-ON ()

When the AC adapter is plugged in, the display is automatically turned on without the ON:OFF key
operation, to display the weighing mode. Used when the balance is built into an automated system. Halfan hour warm up is necessary for accurate weighing.

Auto power-OFF ()

This is a function to turn off only the display automatically when there is no operation made for acertain amount of time (approximately 10 minutes) while the power is on.

Readability ()

When weighing with rough precision, the readability can be turned off without key operation. This isuseful when built into an automated system.

Buzzer ()

Select ON/OFF for the built-in buzzer that sounds when a key is operated or the status changes.

Display when power-on ()

Backlight brightness ()

After turning on the power supply, the display will not be automatically set to zero, and it will start fromthe previous weighing value. This is useful when a hopper, etc. is attached to the weighing pan and thepower needs to be turned off while weighing discharge.

Select the brightness of the backlight of the LCD display.

and LL by LO blinking. By using GXM-04, it is possible to output the comparison result at thecontact point.
There are three types of scope that can be selected as follows.
 No comparison
 Comparison when the weight data is stable or overloaded Continuous comparison
The conditions for comparing near zero are in six levels from "including near zero" to "± 100 d".
"Upper limit value and lower limit value" and "reference value and tolerance range" are the comparison
standards.
There are "Digital input" and "Input by sample load" as input method for each value.
Refer to the function setting.

Refer to "16. Gross Net Tare Function".

7412. ID Number And GLP Report12-1 Main Objective
The ID number is used to identify the balance when Good Laboratory Practice (GLP) or Good
Manufacturing Practice (GMP) is used.
The data output compatible with "GLP/GMP" can be output to a personal computer or printer using
the RS-232C serial interface.
The GLP/GMP compliant report includes the balance manufacturer, model, serial number, ID
number, date, time and space for signature. It includes the results and using mass for sensitivity
adjustment or calibration test data.
The balance can output the following reports for GLP / GMP.
"Sensitivity adjustment report" of the sensitivity adjustment, using the internal mass
(Sensitivity adjustment due to changes in temperature and one-touch sensitivity adjustment.)"Sensitivity adjustment report" of the sensitivity adjustment, using an external weight.
"Calibration test report" of the sensitivity adjustment test, using an external weight.
"Title block" and "End block" for the weighing data.
Sensitivity adjustment and calibration test data can be stored in memory to output several reports atthe same time. Refer to "13. Data Memory" for details.
The ID number is used to identify the balance when the balance is used for maintenancemanagement.
The ID number is maintained in non-volatile memory even if the AC adapter is removed.
For details on confirming and setting the time and date. Refer to "11-4 Clock and Calendar
Function".
It is also possible to output the clock data of an external device (such as a printer) without
outputting data of the clock built in to the balance.
When printing GLP output with an AD-8127 multi-functional compact printer connected to thebalance, the time and date can be printed using the printer's clock function (set "(GLP output)"of "(Data output)" in the function table ("11. Function Table") to " (Outputs with an external
clock)").
Centralized management with the AD-8127’s password lock function is effective in preventing
falsification of the time and date. To output data compliant with GLP, GMP, etc., the AD-8127 printermust be set to dump printing mode. When the external key print mode is in use for printing theweighing value, pressing and holding the ENT key of the AD-8127 (for about 2 seconds) switches
between the external key printing mode and dump printing mode.

The statistical calculation mode statistically calculates the weight data, and displays or outputs theresults. To use the statistical calculation mode, set the "Application function ()" parameter of“Application ()" in the function table to " ", as described below. To return to the normal weighing
mode (factory setting), set "Application mode ()" to " ".
Statistical items available are number of data, sum, maximum, minimum, range (maximum-minimum),average, standard deviation and coefficient of variation. What statistical items to output can beselected from the four modes in the function table ().
The wrong data input can be canceled by the key operation, if immediately after the input.
Turning the balance off will delete the statistical data.
The standard deviation and coefficient of variation are obtained by the equation below:
Standard deviation=

The balance has a "flow mode" that calculates the amount of change in the weighing value per hour.
For details, please refer to "Supplementary information" which can be downloaded from the A&D
website (https://www.aandd.jp).
If the flow unit is set to mL/*, density can be registered. The maximum number of registrations is 10,
and if density is set in advance, it can be selected according to the measurement sample.
The flow rate value is calculated by the following formula.

17. Minimum Weighing Warning Function
The minimum weight is the minimum necessary amount of sample to be used for correctly performing
quantitatively performing quantitative analysis, taking into consideration measurement error of thebalance. If the amount of sample is too small, the proportion of the measurement error in themeasured value increases accordingly, and the reliability of the analysis result may drop.
By using the minimum weighing warning function, it is possible to judge at a glance whether theamount of sample meets the set minimum weight. This function can be used only in "g" mode.
"" is displayed at the top of the unit part when in use.
When the amount of sample is less than the set minimum weight, the "" indication flashes.
When the amount of sample reaches the minimum weight or more, the "" indicator will turn off.
The minimum weight can be changed from the function setting.
The factory setting is 0 g. If the set value is 0 g, no warning will be displayed even if the minimum
weighing warning function is ON (or ). Also, a value greater than weighing capacity cannot
be set as minimum weight. There are two kinds of warning display as follows"Excluding near zero""Including near zero"
Near zero is within ± 10 d of 0 g.
* "d" is a unit of readability.

Repeatability is an indicator of variations in measured values when the same weight is repeatedly
loaded and unloaded, and it is usually expressed in terms of standard deviation (σn-1).
The GX-M series has a built-in weight. With the repeatability check function, the balance obtains 10
measurement data using the built-in weight and displays its standard deviation. By installing thebalance and using this function, it is possible to check repeatability in the environment where thebalance is installed.
Note: This function is available for firmware versions 1.010 or later.
Ex. "Standard deviation = 10.0mg" means that the result of repeated measurements of thesame weighing material falls within the range ±10.0mg at a frequency of about 68%.

27-1 Checking the Balance Performance and Environment
The balance is a precision instrument. When the operating environment or the operating method isinadequate, correct weighing cannot 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. "Frequently asked questions" and their answers are also posted on our
website (https://www.aandd.jp/).

1. Checking that the balance performs properly

Please check the operation of the balance by the self diagnosis function. Refer to "8-2
Self-Check-Function / Automatic Setting of Minimum Weight". Fatal faults are indicated bymessages.
Check the balance performance using an external weight. Be sure to place the weight in thecenter of the weighing pan.
Check the balance repeatability, linearity and weighing value using external weights with aknown value.

2. Checking that the operating environment or weighing method is proper
operating environment
Is the weighing table solid enough? (Especially 0.001 g model)
Is the balance level? Refer to "3. Precautions" How to adjust the bubble spirit level.
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 rim touch anything? Is the weighing pan assembly 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 sensitivity adjustment been performed with the balance in advance?
Has the balance been warmed up for one hour before weighing?
Sample and containerHas the sample absorbed or lost moisture due to the ambient conditions such as temperatureand 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? There are cautions about weighing magnetic
materials. Refer to "3-2 During Use".
