1-3 About The GX-AE Series

□ An ionizer (static eliminator), which causes no breeze, is built into the breeze break. The ionizer

can eliminate static electricity from the weighing sample before weighing, reducing error due to

static electricity. (Static is eliminated by bipolar ions generated by direct-current corona discharge

being projected onto the sample.) □ The ionizer electrodes are designed to be removed for cleaning and replacement. □ An IR (touchless) switch is attached to the ionizer, and static elimination can be started without

touching ionizer. □ Power is supplied from the balance to allow the ionizer to be operated without using an AC adapter. □ PRINT or RE-ZERO or the static elimination function of the ionizer can be operated by using the

optional foot switch (AX-SW137-PRINT or AX-SW137-REZERO). □ A removable glass breeze break is equipped as standard. □ As an option board is installed, so other options (GXA-03/04/06/09/17/23/24/25/26, FXi-08, etc.)

cannot be used. □ For instructions on using the ionizer and IR switch, download the instruction manual for "GXA-17

Large Glass Breeze Break with Ionizer" from our website (https://www.aandd.jp) and refer to it.

Static electricity

In general, when the ambient humidity is less than 45%RH, nonconductors such as powders, paper, and plastics easily become charged with static electricity. The influence of static electricity may cause a weighing error of several milligrams. The ionizer neutralizes this electrical charge.

2-1 Installing The Balance

Step 1. Decide where to install the balance, taking into consideration the content of “2-2 Precautions”, below. Step 2. Assemble the balance while referring to the explanations in the previous section. Step 3. To level the balance, adjust the leveling feet so that the air bubble is in the red circle of the

bubble spirit level. Step 4. Confirm that the adapter type is correct for the local voltage and power receptacle type. Step 5. Insert the AC adapter into the AC adapter jack on the rear of the balance, and then plug the

AC adapter into an outlet.

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°C ±2°C at about 45~60%RH relative humidity. □ Install the balance where it is free of dust. □ The weighing table should be solid, free from vibration and drafts, and as level as possible. (An

anti-vibration table or stone table is ideal) □ 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. □ Be sure to warm up the balance before use for at least 30

minutes (with the AC adapter connected to the power

supply). □ Adjust the sensitivity of the balance before use or after

having moved it to another location. Refer to "7. Sensitivity

adjustment".

The GX-AWP/GF-AWP series

□ The dustproof and waterproof level of the balance 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 or submersion in water may cause water to enter the balance and cause a malfunction. □ When installing and using the balance under conditions requiring dustproof and waterproof

performance, make sure that the AC adapter plug is fully inserted into the AC adapter jack and that

the terminal cover is attached to the RS-232C interface or the waterproof RS-232C cable

(AXKO2737-500) is used. □ If the RS-232C terminal cover is removed or the waterproof RS-232C cable (AX-KO2737-500) is not

used, protection against dust and water is not provided.

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.

The Charged sample

Ground the balance and perform the following as needed.  Use the built-in ionizer to remove static electricity (GX-AE

Metal case

series only).

 Use the GXA-25 or AD-1683 static eliminator, sold separately,

to directly remove static electricity from the sample.

 Increase the relative humidity at the place where the balance

is installed.

 Weigh the sample in a conductive metal container or the like.

Ground

 Wipe off charged materials such as plastic with a damp cloth

to suppress static electricity.

□ On models that come standard with a small breeze break, the parts of the small breeze break may

be charged for some time after being unpacked or when the humidity is low. If the measured value is not stable or repeatability is poor, remove the small breeze break and try again. Wipe the transparent plates with a damp cloth to remove static electricity to solve the problem of them becoming charged. It is also effective to use the GXA-25 or AD-1683 static eliminator, sold separately, or a commercially available antistatic agent.

□ 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

Magnetic material

container). For example, when the room temperature is 20 °C, convection occurs around a flask 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

Convection

40 C

20 C

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.

□ Do not leave the sample on the weighing pan for an extended

period of time. If a sample is left on the weighing pan for a long time, the measured value will change due to deviation from the zero point caused by environmental changes or due to creep phenomenon.

□ 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 RE-ZERO 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.

□ It is advisable to use the standard accessory display protection

cover in order to prevent foreign substances such as powder, liquid and metal pieces from entering the balance.

GX-AWP/GF-AWP series

□ The balance is dustproof and waterproof, and the case is highly airtight. Therefore, for example,

minute pressure fluctuations in the chamber caused by opening and closing the door may cause instability of the display. Before weighing, allow the pressure fluctuations to settle.

□ If water droplets or powder remains on the waterproof diaphragm and the pan support boss, the

performance of the balance may be impaired. Please clean the balance before using it.

□ If the waterproof diaphragm is deformed due to overload, etc., the weighing value may become

unstable until the deformation subsides.

2-4 Precautions 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.

□ The GX-AWP/GF-AWP series is dustproof and waterproof, but it cannot withstand water pressure

due to submersion and the like.

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. Please warm up the balance for at least 30 minutes (one hour for 0.0001g models).

About the operation at when power is turned on

The balance will determine the reference zero point when the ON:OFF key is pressed to enter the weighing mode. Depending on the load condition at that time, it will automatically judge whether to perform zero or tare 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.

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 which is used is "zero range", and when zero range is exceeded, the tare subtraction operation is performed.

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.

4-3 Counting Mode (PCS)

This is the mode to check the number of pieces. Based on the unit mass of the reference sample (weight of one piece), the balance calculates and displays how many pieces are weighed. The smaller the variation in the unit mass, the more accurate the count (the number of pieces). In addition, the ACAI function described later can be used to further improve the counting accuracy while weighing.

Note

* It is recommended that the unit mass (weight of one piece) of the sample to be weighed should

be at least 10 times the readability (g) of the balance.

* If there is a large variation in the sample unit mass values, it may not be possible to count

accurately.

* If counting error is large, frequent use of the ACAI function is advisable. As one of the other

methods, try dividing the measurement into multiple times.

Selecting the counting mode

1. Press the MODE key to select PC5 ( PC5 = unit)

Storing a sample unit mass

2. Press the SAMPLE key to enter the sample unit mass storing

mode. Note that even in the storing mode, pressing the MODE. key switches to the next mode.

3. To select the number of samples, press the SAMPLE key several times. (1025501005 pieces)

Note

Since the sample unit mass is usually considered to have some

variation, the larger the number of samples for registration, the more accurate the count can be.

4. Place a container on the weighing pan, if necessary.

Press the RE-ZERO key to cancel the weight (tare). The number specified in step 3 appears.

25.0 is displayed if 25 is selected in step 3.

5. Place the specified number of samples on the pan. In this example, 25 pieces.

6. Press the PRINT key to store the unit mass. The count display appears. (e.g. 25 PC5 is displayed with 25 pieces.)

Note

* The balance prompts to add more samples if it judges that the

loaded sample is too light (resulting in large counting error). Add the displayed number of samples and press the PRINT key again. When the unit mass is stored correctly, the counting display appears.

* If the balance judges that the mass of the sample is too light to

be registered as the unit mass, it displays Lo .

* Registered unit mass is stored even when the power is turned off.

Automatic Counting Accuracy Improvement (ACAI)

This function automatically improves the counting accuracy as the

number of samples increases. (Errors will be reduced as sample weight variations are averaged.)

After registering the unit mass in step 6, proceed to step 8 below.

8. Add a few samples. Then the processing indicator turns on. (Three or more samples are required

in order to prevent errors. The processing indicator does not turn on if overloaded. Add as many samples as the displayed number.)

9. Do not touch or move the samples on the pan while the processing indicator is blinking. (The

accuracy is being updated.)

10. The accuracy is updated after the processing indicator turns out. Each time this process is repeated, the counting accuracy will improve further. The range of ACAI after exceeding 100 is not predetermined. Add as many samples as the displayed number.

11. Remove all the samples used with ACAI from the pan and start counting work.

Note

□ Do not change units during ACAI processing.

4-5 Animal Weighing Mode (Hold Function)

This is the mode to weigh a moving object such as an animal, even when the display of the weighing

data fluctuates. The hold function allows the average weight of the animal to be displayed. To use the hold function, set the function in the function table. Refer to "9. Function Table" and "9-3 Description Of The Class Environment Display" for details.

5. Impact Shock Detection Function

The GX-AE/GX-A/GF-A 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.

record is kept in the balance when there is a shock impact.

Note

□ 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.
