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.

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-

  1. 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).

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 (

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”.

Example 1 Outputting the function table information to a printer
Use an AD-8127 multi-functional compact printer. 1. Connect the balance and the printer.
Set the print mode to “DUMP”. For details about the settings and print modes, refer to the instruction manual of the printer. For connection between the balance and the printer, refer to “21. Connecting Peripheral Devices”. 2. Make sure that communication is possible between the balance and the printer, then perform the output operation according to “Procedure for batch output of the function table information” in “9-2-1. Output of the function table information”.
Example 2 Outputting the function table information to a personal computer
For USB settings and details of the WinCT software, refer to “21-5. Connecting to a PC” in “21. Connecting Peripheral Devices”, or the WinCT manuals on our website (https://www.aandd.jp). 1. Connect the balance and the PC with the supplied USB cable or RS-232C cable (sold separately)

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
