1. Introduction
Thank you for purchasing A&D’s GX-L/GF-L series high-capacity electronic
balance. Please read this instruction manual carefully to understand and make
full use of the balance before using it.
1-1. Features
The balance has a self-check function that inspects the balance itself using
electronically controlled load (ECL) and evaluates repeatability performance.
The balance can detect the impact applied to its mass sensor, and display and
store the impact level. Impact Shock Detection (ISD) Continuous weight change
can be calculated, displayed, and output as flow rate. Flow Rate Display (FRD)
Equipped with a data memory function to store weighing values, sensitivity
adjustment records, and multiple unit weights (mass per sample in counting
mode). (For weighing values, up to 200 values can be stored.) The GX-L series
has automatic self sensitivity adjustment function using the internal weight,
adapting to temperature 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 is possible to record the sensitivity adjustment/calibration
test results. GLP: Good Laboratory Practice. Standards for implementing safety
tests for drugs and medicines. GMP: Good Manufacturing Practice. Rules for
manufacturing and quality control. The clock function built into the balance
allows you to output the weighing value with the date and time. (The clock
settings can be restricted so that only the Administrator can change them.
[Password function]) Comparing the weighing value and the preset upper/lower
limit value, the comparator Indicators can display the comparison results with
the HI / OK / LO indicator. (5-step comparison setting is also available.)
Capacity Indicator displaying the weight value in percentage relative to the
weighing capacity. Hold Function is provided for weighing a moving object such
as an animal. For measuring density or weighing magnetic materials, the
optional GP-20/21 underhook can be used. With the password function, the use
of the balance and the operation of changing the function table can be
restricted. With the key lock function, the key operation can be disabled and
the balance can be operated only by a command from an external device. RS-232C
and USB interfaces for outputting the weighing value and data of the balance
are equipped as standard. Windows Communication Tools Software (WinCT) makes
it easy to communicate with a Windows personal computer. The latest version of
WinCT is available for download on A&D website. Windows is the trademark of
the Microsoft Corporation., registered in the U.S. and other countries and
regions.

Tips
If the position of the bubble is misaligned significantly from the center circle of the bubble spirit level, will be displayed. In that case, adjust the bubble spirit level so that the bubble is inside the center circle of
the bubble spirit level since the balance main unit may be tilted. Alternatively, press any key other than the
ON:OFF key to cancel the
display. Note that the
display is no longer enabled after
being canceled by pressing the key. To enable the
display, unplug the AC adapter and plug it in
again to turn off the power.
By performing sensitivity adjustment, the current installation state is stored as level reference. For sensitivity
adjustment, refer to “7. Sensitivity Adjustment / Calibration Test”.

2-2. Precautions before use (Installation considerations and preparation)
Prepare the following installation conditions in order to bring out the full performance of the balance.
This product is a high precision balance with a maximum resolution of 1/600,000. The balance tends to be
susceptible to temperature changes, pressure fluctuations, vibration, drafts, and other factors at the
installation site. In particular, during sensitivity adjustment with the internal weight, a weighing value that is
one digit smaller than the readability of the balance is read, so be careful of the above error factors and
perform weighing operations in a stable environment.
The best operating temperature is about 20°C ±2°C at about 45% to 60% RH relative humidity.
Install the balance where it is free of dust.
Place the balance on a solid, flat floor. (Do not install on a soft floor.)
The weighing table should be solid. (An anti-vibration table or stone table is ideal.)
Make sure there is no tilt in the installation location.
Install the balance in a stable location, avoiding vibration and shock. Corners of rooms on the first floor of
a building, i.e. the floor which is level with the ground, are best as they are less prone to vibration.
Install the balance where it is not affected by heaters or air conditioners. Avoid breezes and drafts in the
room.
Avoid locations in direct sunlight.
Install the balance away from equipment which produces magnetic
fields. Level the balance by adjusting the leveling feet so that the bubble of the bubble spirit level is centered in the circle. Be sure to warm up the balance before use for at least 30 minutes
Main unit rear side

with the AC adapter connected to the power supply.
When the balance is installed for the first time or has been moved,
warm up the balance for at least 12 hours to allow the balance to
reach equilibrium with the ambient temperature, and then perform sensitivity adjustment before use. For details, refer to “7.
Bubble
Leveling foot
spirit level
Sensitivity Adjustment / Calibration Test”.
The balance’s dustproof and drip-proof 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 installing and using the balance under conditions requiring dustproof and drip-proof performance,
make sure that the weighing pan is installed on the main unit, that the cable for connecting the main unit
and display unit is attached (for separate type models), that the AC adapter plug is fully inserted into the
AC adapter jack, that the terminal cover is attached to the RS-232C interface or a waterproof RS-232C
cable (AX-KO2737-500) is used, and that the USB waterproof cover cap is attached or the USB connector
is firmly inserted.
If the weighing pan or RS-232C terminal cover is removed or a waterproof RS- 232C cable (AX-KO2737-
- is not used, protection against dustproof and water is not provided.
Errors due to moving the weighing system:
The performance of this product is guaranteed when it is used in a stationary condition. If the balance is
incorporated into a system that moves the balance, you must carefully perform checks in advance 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,
13
and provide a sufficient waiting time for the weighing value to stabilize when
acquiring weighing data. The moving device should have a structure where the
balance can be kept level. If the level 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.
CAUTION
Please confirm that the AC adapter type is correct for your local voltage and
receptacle type. Do not install the balance where flammable or corrosive gas
is present.
14
2-3. Precautions during use (for more accurate weighing)
For precise and accurate weighing, please take notice of the following. Weighing errors may occur due to the influence of static electricity. Note that if the ambient humidity drops below 45%RH, insulators such as plastics are liable to have static electricity. Ground the balance and perform the following as needed. Use the AD1683A ionizer (sold separately) to remove static electricity from the charged sample directly. Increase the relative humidity at the place where the balance is installed. Weigh the sample in a conductive metal container or the like. Wipe off charged materials such as plastic with a damp cloth to suppress static electricity. Influence of magnetism may cause weighing errors. When measuring magnetic materials (iron, etc.), keep the sample away from the balance main body by means such as underhook weighing. Weighing errors may occur if there is a difference between the ambient temperature and temperature of the sample (and the container). For example, when the room temperature is 20 °C, convection occurs around a Petri dish or watch glass that is 40 °C and the balance displays a value lighter than the actual weight. Before weighing the sample and the container, try to acclimatize them to the ambient temperature. Perform the weighing operation carefully and quickly. If measurement takes a long time, error-inducing factors will increase due to changes in temperature and humidity in the weighing chamber, air turbulence or reaction/humidity absorption by the sample. When placing a sample on the weighing pan, do not drop it, or do not place a sample greater than the balance weighing capacity. Place the sample in the center of the weighing pan. When pressing keys, do not press with a sharp object such as a pen. Instead, press the center of the key with your finger. Be sure to press the ZERO key or TARE key before weighing in order to eliminate measurement errors. Measurement results include error from air buoyancy. The buoyancy of air varies depending on the sample volume, atmospheric pressure, temperature, and humidity. Correct the buoyancy for the most precise measurement. Prevent foreign substances such as powder, liquid, and metal pieces from entering the balance.

2-4. Cautions after use
Avoid mechanical shock to the balance. Do not disassemble the balance. Prevent
foreign substances such as powder, liquid and metal pieces from entering the
balance. Do not use any strong organic solvents to clean the balance. Clean
the balance with a lint free cloth that is moistened with a mild detergent.
The weighing pan can be removed for easy cleaning around the pan. When the
weighing pan is removed, the air-permeable filters for pressure relief are
exposed. Do not get the air-permeable filters wet. Do not allow the balance to
be immersed in water. Even though the balance complies with IP65 (Dust-tight
and Protected Against Water Jets), the balance will not withstand being
completely immersed in water.

2-5. Caution on the power supply
Do not remove the AC adapter while the internal weight is in motion, for
example, right after the AC adapter is connected, or during sensitivity
adjustment using the internal weight. If the AC adapter is removed under the
conditions described above, the internal weight 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. The balance
is constantly provided with power as long as the AC adapter is connected. The
balance is not adversely affected in this state. It is advisable to always
keep the balance in this state for accurate weighing.

Zero-point setting, tare subtraction operation, and weighing range
At the start of weighing 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 perform zeroing or
tare subtraction operation. The condition for determining which is used is
“power on zero range”, and when power on zero range is exceeded, the tare
subtraction operation is performed.

4-3. Counting mode (PCS)
This is the mode to determine the number of objects in a sample. Based on the
reference sample unit weight (weight per piece), the balance calculates and
displays how many pieces the sample weight corresponds to. The smaller the
variation in the unit weight of sample pieces is, the more accurate the count
will be. The balance is equipped with the Automatic Counting Accuracy
Improvement (ACAI) function to improve the counting accuracy.
It is recommended that the unit weight (weight per piece) of the sample should
be at least 10 times the gram readability of the balance. If there is a large
variation in the unit weight of sample pieces, it may not be possible to count
accurately. If a large error is found in the counting measurement, try a
method such as performing ACAI function frequently or multiple measurements.
Selecting the counting mode
1. Press the MODE key to set the unit display to ” ” (pieces).
Storing a sample unit weight
2. Press the SAMPLE key to enter the unit weight storing mode.
3. Select the number of sample pieces using the SAMPLE key. (10 pcs -> 25 pcs -> 50 pcs -> 100 pcs -> 5 pcs) Note that a greater number of sample pieces at time of unit weight storing will yield more accurate counting result since the sample unit weight is usually considered to vary slightly.
4. Place a container on the weighing pan, if necessary. Press the TARE
key to set the display to

The balance prompts to add more sample pieces if it judges that
the loaded sample is too light (resulting in large counting error). Add
more sample pieces until the displayed number is reached, and
then press the PRINT key again. When the unit weight is stored
correctly, the balance displays the count. If the balance judges that the sample is too light to be stored as the
unit weight, it displays

in sample weight are averaged.)
After storing the unit weight in step 6, proceed to step 8 below.
8. Add a few sample pieces. The processing indicator then turns on. (Three or more pieces are required in
order to prevent errors. The processing indicator does not turn on if overloaded. Add approximately the same
number of sample pieces as displayed.)
9. Do not touch or move the sample pieces while the processing indicator is blinking. (The accuracy is being
updated.)
10. The accuracy is updated after the processing indicator turns off. Each time this process is repeated, the
counting accuracy will improve further. The range of ACAI after exceeding 100 is not predetermined. Add
approximately the same number of sample pieces as displayed.
11. Remove all the sample pieces used with ACAI from the weighing pan and start counting work.
Note Do not change units during ACAI processing.

5. Impact Shock Detection (ISD) Function
The GX-L/GF-L series has a function to detect impact shocks 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.
The shock indicator has 5 levels from level 0 to level 4.

Even if the impact shock detection function is turned off, a record is kept in the balance when there is a shock
impact.
Caution
Impact on the weighing sensor is not only that applied to the weighing pan
when loaded, but also may be impact applied from the table on which the
balance is installed. The impact detection function also works for impact
coming from the table.
5-1. Recording impact history
Impacts of impact level 3 or higher are stored on the balance with data and time (up to 50 instances).
When the password lock function is ON (
or ), the login user information is added when outputting
the impact history.
Caution
If data instances exceed 50, the stored data with the lowest impact level will
be overwritten. The stored impact history cannot be deleted. Impact data where
the balance is not energized (during transport, etc.) is not stored.

7. 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 to keep the weighing values
from changing even if gravity or the environment changes. It is recommended
that you perform sensitivity adjustment if the balance is installed for the
first time or relocated, or when the weighing values change significantly in
daily inspection, etc. Sensitivity adjustment means to adjust the weighing
value of the balance using the reference weight or internal weight.
Calibration test is to weigh with the reference weight and compare how much
the result deviates from the reference value. (Sensitivity adjustment is not
performed in calibration test.)
Sensitivity adjustment
Automatic sensitivity adjustment ———————— Automatically adjusts the balance
using the internal weight according to ambient temperature change/interval
time. (GX-L series)
Sensitivity adjustment using the internal weight —– Using the internal weight,
adjusts the balance with one key press.
Sensitivity adjustment using an external weight —– Using an external weight,
adjusts the balance.
Calibration test
Calibration test using an external weight ————– Outputs the result of the weighing accuracy check using an external weight. * No sensitivity adjustment is performed.
Cautions on sensitivity adjustment
Do not allow vibration or drafts to affect the balance during sensitivity adjustment.
When outputting the maintenance report compliant with GLP, GMP, etc. during sensitivity adjustment:
To output the maintenance report compliant with GLP, GMP, etc., “GLP output (
)” of “Data output
(
)” in the function table must be set. GLP output requires a PC or optional printer. For GLP output,
the balance’s clock function will output the date and time. Refer to “9-4. Clock and calendar function” in “9.
Function Table” and set the clock if the date and time are not correct.
Note that the calibration test function is available only when output of the maintenance report compliant
with GLP, GMP, etc. is set.
To store in memory the sensitivity adjustment report or calibration test report, “Data memory (
)” in
the function table must be changed.
Cautions on the use of external weights
The accuracy of the weight used for sensitivity adjustment determines the
accuracy of the balance after sensitivity adjustment. Refer to the table on
the next page to select the weight to be used for the sensitivity
adjustment/calibration test using an external weight.

7-1. Automatic sensitivity adjustment (GX-L series only)
This function automatically adjusts the sensitivity of the balance according to ambient temperature change, set
time or interval time using the internal weight. It works even when the display is off. After sensitivity adjustment,
the balance will output the “sensitivity adjustment report” if GLP output is set in the function table.
For the automatic sensitivity adjustment mode, “Temperature change (
)”, “Set time (
)”, or
“Interval time (
)” can be set in “Sensitivity adjustment mode ( )” of the function table.
For the set time,
,
, and
are available in the function table.
The Interval time can be set in the range of 0.5 hours to 24 hours in “Interval time ( )” of the function
table.
Caution
If something is on the weighing pan, the balance itself will judge that it is
in use and will not perform automatic sensitivity adjustment. The criteria for
performing automatic sensitivity adjustment are as follows.
0.1 g model 200 g or more
1 g model 2 kg or more
To maintain the correct sensitivity adjustment of the balance, do not place anything on the weighing pan while not in use.
The automatic sensitivity adjustment notice (the indicator
blinking)
indicates that the automatic sensitivity adjustment will start. If the balance is
not in use, after blinking for a while, the balance will start automatic sensitivity
adjustment using the internal weight. (The blinking duration depends on the
environment.)
Indicates that the balance is measuring sensitivity adjustment 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.
If the balance is determined to be tilted, automatic sensitivity adjustment will not be performed. Check the
bubble spirit level to see if the bubble is in the center circle.
Note that if the automatic level detection & warning is set to off (
) in the function table
,
automatic sensitivity adjustment is performed even if the balance is tilted.
Tips
Although it is possible to continue using the balance even while the automatic
sensitivity adjustment notice (the indicator) is blinking, use after
sensitivity adjustment is completed is advisable in order to maintain the
weighing accuracy. “Prohibit automatic sensitivity adjustment” or “Allow
automatic sensitivity adjustment” can be selected in the setting described in
“8. Function Selection Switch and Initialization”.

9-3. Description of the class “Environment/Display”
Condition ( )
Sensitive response to fluctuation of a weighing value: For powder or liquid
target weighing, weighing a very light sample, or when work efficiency is
required rather than display stability, set the parameter to be a small value.
When set, FAST is displayed.
Slow response to fluctuation of a weighing value: To prevent the weighing value from drifting due to vibration or drafts, set the parameter to be a high value. When set, SLOW is displayed.
Stability band width ( )
This item is to control the width to regard a weighing value as a stable value. When the fluctuation range of
weighing value within a certain period of time is less than the parameter, the balance displays the
stabilization indicator and the data can be output (or stored) as set in the function table ( ,
, etc.).
This setting influences “auto print mode”. “d” (readability digit) is the unit of readability.
E.g. For the GX-62001L, if 1 g display is selected with the SAMPLE key, 1 g is 1 d.
(±1 d)
The stabilization indicator will not display if the value is not stable enough, and it will disappear if there are even slight fluctuations in the weighing value. To perform weighing with strict judgment, set the parameter to a low value.
(±3 d)
The stabilization indicator becomes less responsive to slight fluctuations in the weighing value. To prevent the weighing value from drifting due to factors such as the usage environment, set the parameter to a high value.
Hold function ( )
Mode A (Average hold, animal weighing) 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 weighing data. When the animal or
sample is removed from the weighing pan, the display holds the displayed value
for five seconds and then returns to zero automatically. This function is
available only when the hold function parameter is set to ” ” (the display
hold mark HOLD illuminates) and any weighing unit other than the counting mode
is selected. The stabilization range and averaging time are set in “Condition
( )” and “Stability band width ( )” in the function table.

B mode (hold when stable) When the weighing value is beyond a certain range
from zero (same weighing range as mode A) and the stabilization indicator
lights up, the displayed value is held. When the object to be weighed is
unloaded, the display is automatically set to zero after the display is
maintained for 5 seconds. This function is available when the balance is in
other than counting mode.
Zero tracking ( )
This function automatically tracks zero-point drift caused by changes in the
environment and stabilizes the zero display. When the weighing value is only a
few digits, turn the function off for accurate weighing. “d” (readability
digit) is the unit of readability.
The tracking function is not used. When the weighing value is only a few
digits, turn the function off for accurate weighing. The tracking function is
used. Normal zero tracking. (±1 d / 1 second) The tracking function is used.
Strong zero tracking. (±1 d / 0.5 seconds) The tracking function is used. Very
strong zero tracking. (±1 d / 0.2 seconds)
Display refresh rate ( )
The periodic time to refresh the display. This timing also applies to data
output. This parameter influences “baud rate”, “data output pause” and the
operation in the stream mode.
Decimal separator ( )
A symbol used as a decimal separator (point/comma) can be selected.
Auto power-ON ( )
When the AC adapter is plugged in, the display is automatically turned on
without pressing the ON:OFF key and the balance enters weighing mode. This
function is used when the balance is built into an automated system. Be sure
to warm up the balance before use for more than half an hour for accurate
weighing.
Auto power-OFF ( )
This is a function to automatically turn off only the display when there is no
operation made for a certain amount of time (approx. 10 minutes) while the
power is on.
Readability ( )
When weighing with rough precision, the readability can be turned off without
key operation. This is useful when built into an automated system.
Buzzer ( )
Select ON / OFF for the built-in buzzer that sounds when a key is operated or
the state changes.
76
Display when power-on (
)
You can choose whether the balance will automatically zero the display when the power is turned on or start
from the previous weighing value without automatically zeroing the display when the power is turned on.
The tare value memory is useful when a hopper or other device is attached to the weighing pan and the
power must be turned off during discharge weighing. Note that this function is disabled when the hold
function is on.
Backlight brightness (
)
Select the brightness of the backlight of the LCD display.
Bubble sprit level lighting ( )
Select ON / OFF for the LED that illuminates the bubble sprit level.
Impact shock detection ( )
Select ON / OFF for the function to display impact level.
Automatic level detection & warning ( )
This is a function that displays
by the level detection sensor when the balance is significantly tilted,
prompting the user to adjust the level of the balance. Note that
is displayed only when the display
is zero.
77
9-4. Clock and calendar function
