load (ECL) and evaluates performance. Read this manual thoroughly before using the balance 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, calibration
result, and multiple unit mass (mass per sample in counting mode) (Up to 200 items are stored for
weighing value).
The GX-A series has automatic self calibration using the internal mass, adapting to temperature
changes, setting time and interval time.
Good laboratory practice (GLP) / Good manufacturing practice (GMP) data can be output using the
RS-232C serial interface.
A built-in clock and calendar that can add the time and date to the output data.

2-2
Precautions
To get the optimum performance from the balance and acquire accurate weighing data, note
the following:
□ Install the balance in an environment where the temperature and humidity are not excessive.
The best operating temperature is about 20℃±2℃ at about 45~60%RH relative humidity.
□ Install the balance where it is free of dust.
□ The weighing table should be solid and free from vibration, drafts and as level as possible.
□ 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.
□ Install the balance where it is not affected by heaters or air conditioners.
□ Install the balance where it is not exposed to direct sunlight.
□ Install the balance away from equipment which produces magnetic fields.
□ Level the balance by adjusting the leveling feet and confirm it using the
bubble spirit level.
□ Warm up the balance for at least 30 minutes. Plug in the AC adapter as
usual.

During Use
To acquire accurate weighing data, note the following:
□ Discharge static electricity from the material to be weighed. When a
sample could have a static charge, the weighing data is influenced. If
the ambient humidity becomes 45% or less, insulators such as
plastics are liable to become static electricity. Ground the balance
and try the following.
Eliminate the static electricity by GXA-25, AD-1683 as an accessory.
Or try to keep highly the ambient humidity
Or use a metal shield case.
Or wipe a charged plastic sample with the wet cloth.
□ The breeze break (1mg models only) and the clear main unit
cover are provided as accessories. The breeze break
components may be charged with static electricity when they
are unpacked or when the humidity is low. If the weighing value
is unstable or the balance has a problem with repeatability,
remove the breeze break. Or wipe the clear plates with a
moistened cloth, use an accessory DC static eliminator, GXA-25,
AD-1683 or apply an anti-static spray.
□ 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.

□ Cancel the temperature difference between a 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.
□ When placing a sample on a weighing pan, do not give a strong
shock or do not exceed the weighing capacity. And place in the
center.
□ 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.
□ 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.

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.
□ Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid spills
and excessive dust.
2-5
Power Supply
□ 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.

Counting Mode(PCS)
This is the mode to determine the number of objects in a sample based on the standard sample unit
mass. Unit mass means the mass of one sample. The smaller the variables in each sample unit mass is,
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 the minimum
display in grams.

The GX-A / GF-A 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 the
weighing 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 level
as much as possible while checking the shock indicator.
Impact level display is from level 0 to level 4, 5level.

8.Calibration
Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes. It is necessary to perform calibration (sensitivity adjustment) with the weight in
order to keep 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. Calibration is to weigh with the reference weight and compare how much the result deviates
from the reference value. (Adjustment is not performed in calibration.)
Calibration (Sensitivity adjustment)
Auto calibration------------------------------------------ Automatically adjust the balance using the internal mass
depending on the temperature change of the operating
environment or the set time and interval time.(GX-A
series)
Calibration test using the internal mass ---------- Using the internal mass, adjust the balance with a single
touch.
Calibration test using an external weight --------- Using an external mass, adjust the balance with an
external mass.
Calibration test(Sensitivity calibration)
Calibration test with your own weight -------------- Output the result of checking the accuracy of weighing
using your own weight.
*No adjustment is made.
Caution
□ Do not allow vibration or drafts to affect the balance during calibration.
□ To output the data for GLP/GMP using the RS-232C interface, set "GLP/GMP output (info)" of "Data
output (dout)". Refer to "10. 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 "10-4 Clock and Calendar Function".
□ The calibration and calibration test data can be stored in memory. To store them, set "Data memory
(data)" .
□ The accuracy of the weight used in calibration affects the accuracy of the balance after calibration.
□ Select the mass to be used for calibration and calibration tests from the table below.

Description Of The Class "Environment, Display"
Condition ( Cond )
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 ( 5t-b )
This item controls the width to regard a mass 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
by function setting(dout, dataA etc.)The parameter influences the "Auto print mode". Also, the minimum
display being displayed is 1 digit.
ex. If 0.01 mg display is selected by pressing the SAMPLE key on the GX-303A, 0.01 mg is 1 digit.
This parameter is used for sensitive response of the stabilization indicator. Used for
exact 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 ( Hold ) (Animal weighing mode)
This function is used to weigh a moving object such as an animal. When the weighing data is over the
weighing range from zero and the display fluctuation is within the stabilization range for a fixed period of
averaging time, the processing indicator illuminates and the balance displays the average weight of the
animal. When the animal is removed from the weighing pan, the display returns to zero automatically. This
function is available only when the hold function parameter is set to "1" (the animal mode indicator ANIMAL
illuminates) and any weighing unit other than the counting mode is selected. The stabilization range and
averaging time are set in "Condition (Cond)" and "Stability band width (5t-b)".

Zero tracking ( trc )
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 digits, turn the function off for accurate weighing.
trc 0
The tracking function is not used. Used for weighing a very light sample.
trc 1
The normal tracking function is used.(±1 digit / 1 second)
trc 2
The strong tracking function is used. (±1 digit / 0.5 second)
trc 3
The very strong tracking function is used. (±2 digit / 0.2 second)

Display refresh rate ( 5pd )
The periodic time to refresh the display. This parameter influences "Baud rate", "Data output pause"
and the data output rate of "Stream mode".
Decimal point ( pnt )
The decimal point format can be selected.
Auto display-ON ( p-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.
One hour warm up is necessary for accurate weighing.
Auto power-OFF(p-off)
This is a function to turn off only the display automatically when there is no operation made for a
certain amount of time (approximately 10 minutes) while the power is on.
Minimum display(
)
When weighing with rough precision, the minimum display can be turned off without key
operation. This is useful when built into an automated system/
Buzzer(beep)
Select ON/OFF for the built-in buzzer that sounds when a key is operated or the status changes.
Tare value record(
)
After turning on the power supply, the display will not be automatically set to zero, and it will start
from the previous weighing value. This is useful when a hopper, etc. is attached to the weighing pan
and the power needs to be turned off while weighing discharge.
Backlight brightness(
)
Select the brightness of the backlight of the LCD display.
Bubble sprit level lightning(
)
Select ON/OFF for the LED that illuminates the bubble sprit level.

memory are available for outputting at one time to a printer or personal computer.
The following five types of data can be stored.
Unit mass (Counting mode)
Up to 50 sets
Weighing value
Up to 200 sets
Calibration report
Internal calibration
External calibration
Calibration test report
Internal test calibration
External test calibration

Data Memory For Weighing Data
Features
□ It is not necessary to connect the printer or personal computer to the balance continually, because
the balance stores the weighing data in memory.
□ The data in memory can be displayed on the balance for confirmation.
□ Data (ID number, data number, time and date) to be added to the output data can be selected in the
function setting.
□ The balance can store 200 sets of weighing data in memory (if time and date are added, the balance
can store 100 sets).
※ For the unit mass storage method, refer to "5-2 Counting Mode".
Storing the weighing data
Note
1. Set the "Data memory (data)" parameter to " data 2". Refer to "10. Function Table".
2. Specify the "Time/Date output (5-td)" parameter whether time and date is to added or not.
3. The storing mode depends on the "Data output mode (prt)" parameter setting. When set to prt3
(stream mode), data may not be stored correctly.
※ It is also possible to change the time / date setting after storing the weighing value.

14.Flow Measurement
The balance has a "flow mode" that calculates the amount of change in the weighing value per hour.
To use the statistical calculation mode, set the "Application function (apf)" parameter of “Application
(ap fnc)” in the function table to “3”, as described below.
Calculating the flow rate from the weight output of the balance may change the number of weighing
values per unit time, so there is a possibility that the result will not be correct.
The flow mode is calculated at the accurate timing at which the weighing value is updated in the balance,
so it is possible to calculate the correct flow rate value.
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.

16.Minimum Weighing Warning Function
The minimum weighing value is the minimum necessary amount of sample to be used for correctly
performing quantitatively performing quantitative analysis, taking into consideration measurement error of
the balance.
If the amount of sample is too small, the proportion of the measurement error in the measured 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 the amount of
sample meets the set minimum weight value. This function can be used only in "mg or 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 weighing value, the
"
" indication flashes.
When the amount of sample reaches the minimum weighing value or more,
the "
" indicator will turn off
The minimum weighing value can be changed from the function setting. The

21.Maintenance
21-1 Treatment Of The Balance
□ 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.
□ Use the original packing material for transportation.
22.Troubleshooting
22-1 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.
"Frequently asked questions" and their answers are also posted on our website
<http://www.aandd.co.jp>.
1.Checking that the balance performs properly
□ Please check the operation of the balance by the self diagnosis function. Refer to "6-2 Self-diagnosis
Function". Fatal faults are indicated by messages.
□ Check the balance performance 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.
2.Checking that the operating environment or weighing method is proper
Operating environment
□
Is the weighing table solid enough?(Especially 1mg model)
□
Is the balance 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?
Refer to " 2-2 Precaution "How to adjust the bubble spirit level".
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 the balance been calibrated using the internal mass (one-touch calibration)? (Only for GX=A
series)
□ Has the balance been warmed up for one hour before weighing?
92
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
"2-3 During Use".
□ Is the sample charged with static electricity? Refer to "2-3 During Use".
(This occurs especially with 0.001g models when the relative humidity is low.)
□ Is the sample of magnetic material such as iron? There are cautions about weighing magnetic
materials. Refer to "2-3 During Use".

Other Display
When this indicator (
) blinks, automatic self calibration is required. The
indicator blinks when the balance detects changes in ambient temperature. If
the balance is not used for several minutes with this indicator blinking, the
balance performs automatic self calibration. The blinking period depends on
the operating environment.
Advise
22-4
The balance can be used while this indicator is blinking. We recommend that you
perform automatic self calibration for precision weighing.
Asking For Repair
If the balance needs service or repair, contact your local A&D dealer.
The balance is a precision instrument. Use much care when handling the balance and observe the following
when transporting the balance.
□ Use the original packing material for transportation.
□ Remove the weighing pan, pan support, breeze break ring and dust plate from the main unit.
