3. Precautions
To get the optimum performance from the balance and acquire accurate weight data, note the
following:
3-1. Before Use
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 which produces magnetic fields.
Install the balance in a stable place avoiding vibration and shock. Corners of rooms on the floor at the
ground level are best, as they are less prone to vibration.
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)
Level the balance by adjusting the leveling feet and check it using the bubble spirit level.

When the bubble is off to the backward position :
Turn both leveling feet on the front in the
clockwise direction at the same time.
Ensure a stable power source when using the AC adapter.
Plug in the AC adapter and warm up the balance for at least one hour.
Calibrate the balance before use or after having moved it to another location. Refer to “7. Calibration
(Sensitivity adjustment/Calibration)”.
Caution: Do not install the balance where flammable or corrosive gas is present.
When the bubble is off to the right :
Turn the leveling foot on the front left in the
clockwise direction.
When the bubble is off to the forward position:
Turn both leveling feet on the front in the
counterclockwise direction at the same time.
10
3-2. During Use
Discharge static electricity from the material to be weighed
(hereinafter referred to as the sample). When a sample could
have a static charge, the weight data is influenced. Ground
the balance and try the following:
Eliminate static electricity using the optional AD-1683 DC
static eliminator.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case for a charged sample.
Wipe charged plastic samples with a moistened cloth.
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.
Eliminate 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.
Charged material
Material case
Grounding
Magnetic material
Make each weighing gently and quickly to avoid errors caused
by the evaporation of moisture from the sample or the
absorption of moisture by the sample. Use a pair of long
tweezers to place a sample on the pan to avoid placing a hand
inside the breeze break.
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 eliminate possible errors.
Calibrate the balance periodically so as to eliminate 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.
The breeze break (The FZ-CT / FX-CT series) is provided as a standard accessory. An anti-static
treatment has been applied to the breeze break components, but they may be charged with static
electricity when they are unpacked or when the humidity is low. If the weighing value is unstable even
when there are no drafts or the balance has a problem with repeatability, remove the breeze break. Or
wipe the clear plates with a moistened cloth, use the optional AD-1683 DC static eliminator or apply an
anti-static spray.
11
3-3. 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.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid spills
and excessive dust.
Do not use organic solvents or chemical cloth to clean the balance.
Clean the balance as described below:
Balance main unit,
Weighing pan
Breeze break
(standard accessory)
Use a soft, lint free cloth that is moistened with a mild detergent to clean.
The edge of the weighing pan is sharp. Use caution when cleaning the pan.
An antistatic treatment has been applied to the breeze break components.
Use a soft, dry, lint free cloth to clean. Cleaning with a cloth that is moistened
with water or a mild detergent repetitively, or washing with water, may
degrade the antistatic effect.
3-4. Power Supply
When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on
(refer to "4. Display Symbols and Key Operation"). This is a normal state and does not harm the
balance. For accurate weighing, allow the balance to reach equilibrium with room temperature, and
then warm up the balance for at least one hour before use.

Zero operation, tare operation and weighing range
When weighing is started
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, the balance 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 operation is performed.
Re-zero operation
By pressing the RE-ZERO key, the display can be set to zero.
The re-zero operation with the RE-ZERO key will automatically judge whether to perform zero or tare
operation.
The condition for determining which is used is "zero range", and when zero range is exceeded, the tare
operation is performed.
Weighing range
The range that the balance can weigh varies depending on the model.
When the total amount (net weight + tare weight) displayed for each model exceeds the maximum
display, E is displayed to indicate that the weighing range is exceeded.
When exceeded in the negative direction, -E is displayed.

7. Calibration (Sensitivity Adjustment/Sensitivity
Check)
7-1. Calibration Mode
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.
Calibrate the balance if it is installed for the first time or relocated, or when the weighing values change significantly
in daily inspection.
Calibration means to adjust the weighing value of the balance using the reference weight or internal mass.
Calibration test means to weigh with the reference weight and compare how much the result deviates from the
reference value. (Calibration test does not perform adjustment.)
Calibration (Sensitivity adjustment)
Calibration using the internal mass ------------------- Using the internal mass, adjust the balance with a single
touch. (FZ-CT series)
Calibration using an external weight ----------------- Using an external weight, adjust the balance.
Calibration test (Sensitivity check)
Calibration test using an external weight ----------- Checks the accuracy of weighing using an external weight
(target weight) and outputs the result.
* No adjustment is made.
Notes
When calibrating, be sure to install the provided large breeze break.
Do not allow vibration, drafts, or temperature change to affect the balance during calibration.
Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:
The balance is installed for the first time.
The balance has been moved.
The ambient environment has changed.
To output the GLP/GMP compliant report using the RS-232C serial interface, set "GLP output ( info )"
of "Data output ( dout )". For details, refer to "9. Function Table". To display the GLP output, a printer
or personal computer is required.
Calibration test is available only when "GLP output ( info )" of "Data output ( dout )" is set to "1", "2" or
"3".
Note on using an external weight
The accuracy of an external weight will influence the accuracy of weighing. Select an appropriate
weight as listed below:
Model Usable weight Adjustable range
FZ-1200CT / FX-1200CT 250 g, 200 g, 100 g, 50 g, 20 g
-0.0150 g to +0.0150 g FZ-700CT/ FX-700CT 150 g, 100 g, 50 g, 20 g
FZ-500CT/ FX-500CT 100 g, 50 g, 20 g
The calibration weight in bold type: factory setting.
The weight value can be adjusted within the range above.
Display
This indicator means "the balance is measuring calibration data".
Do not allow vibration or drafts to affect the balance while this indicator is
displayed.

allow vibration or drafts to affect the balance.
4 The balance displays end after calibration. If the "GLP output (info)" parameter of the function
table is set, the balance displays glp and outputs the calibration report using the RS-232C
interface. Refer to “GLP output (info)” in "10-2. GLP Report".
5 The balance automatically returns to the weighing mode after calibration.
About the internal mass
The internal mass may change due to corrosion or other damage caused by the operating
environment, or due to aging. The internal mass value can be corrected using an external weight. To
maintain the weighing accuracy, perform the internal mass value correction periodically. Refer to "7-4.
Correcting The Internal Mass Value 1" and "7-7. Correcting The Internal Mass Value 2".
18
7-3. Calibration Test Using the Internal Mass

8-1. Permit or Inhibit
The balance stores parameters that must not be changed unintentionally. There are two switches for
the purpose of protecting these parameters. Each switch can select either “permit” or “inhibit”.
“Inhibit” protects parameters against unintentional operations.
Function selection can be restricted with the password function. When using balances with software
version 1.860 or later, the password function can be used to restrict calibration (sensitivity adjustment)
functions.
The switches for function selection" are as follows:
