SAFETY PRECAUTIONSAll safety messages are identified by the following, "WARNING" or"CAUTION", of ANSI Z535.4 (American National Standard Institute: ProductSafety Signs and Labels). The meanings are as follows:
WARNINGCAUTION

A potentially hazardous situation which, if not
avoided, could result in death or serious injury.
A potentially hazardous situation which, if notavoided, may result in minor or moderate injury.

 This manual is subject to change without notice at any time to improve
the product.
 Product specifications are subject to change without any obligation on
the part of the manufacture.
 When using the scale, the following safety precautions should always
be followed.
WARNINGRepairs
Do not disassemble the scale. Contact your local A&D dealer if yourbalance needs service or repair.
Troubleshooting
If a problem has occurred and you cannot clear it, stop using the scale,place a notice on the scale and request service from the store where
you purchased the balance or from your local A&D dealer.
CAUTION
Conditions for use and Ambient Temperature The scale is a precision instrument. Avoid installing the scale in direct
sunlight, excessive dust, high humidity, high temperature, large temperaturefluctuations or magnetic fields, which may cause problems or malfunctions.
 Drafts and vibration may cause excessive weighing errors.
 Use the scale range of the -10°C to 40°C, with less than 85% R.H.
Operation
 Avoid mechanical shock to the scale, especially to the weighing pan.
That could cause damage.
 Avoid overloading that could cause damage to the scale.
 The scale is not waterproof type. Water invading into the scale may
cause damage.
 If the scale is not to be used for a long period of time, remove allbatteries from the battery compartment to avoid battery leakage.
 Do not mix batteries made by different manufactures, or mix old andnew batteries. Replace all of the batteries at one time.
 Use only the specified AC adapter for the scale (AC adapter is optional).
2Compliance with FCC rules
Please note that this equipment generates, uses and can radiate radio
frequency energy. This equipment has been tested and has been found tocomply with the limits of Class A digital devices pursuant to Part 15 of FCC
rules. These rules are designed to provide reasonable protection againstinterference when equipment is operated in a commercial environment. If
this unit is operated in a residential area, it may cause some interference
and under these circumstances the user would be required to take, at his
own expense, whatever measures are necessary to eliminate theinterference. (FCC = Federal Communications Commission in the U.S.A.)

PREPARATION
Installing Batteries

Battery cover

Step 1 Remove the battery cover.

Step 1

Step 2 Insert 4 new batteries into thebattery compartment, taking careof the polarities.

Step 3 Replace the battery cover.
NoteThe batteries provided with the scale are fortesting the performance of the scale and may have a limited life.

When Using the AC adapter
Step 1 Verify that the AC adapter is correct.
Step 2 Plug the AC adapter into theAC adapter jack.

AC adapter jackPossibility of Electrostatic Influence
When the ambient humidity gets low,
plastics and insulators will be easily charged.
That may make the reading unstable andcause some errors. To reduce theelectrostatic influence, ground the scaleusing a threaded screw hole on the bottom.
A ground wire and a screw are not included.
The depth of the screw hole is 8 mm andprepare an M3 screw so as to fit the hole.

WEIGHING
Step 1 Press the ON:OFF key to turn the scale on. The scale displays all
segments for a few seconds and shows zero.
Press the ON:OFF key again to turn the scale off.
Step 2 Press the UNITS key to select an appropriate weighing unit.
The scale will power up with the same weighing unit as the one in use
when turned off last time.
Step 3 Verify that the reading is zero. If not, press the RE-ZERO key tozero the display. When you use a container for weighing, place anempty container on the weighing pan and press the RE-ZERO key
to zero the display.
Step 4 Place objects to be weighed on the weighing pan or in the container.
Wait for the STABLE  to be displayed and read the value.

5Errors
eeeeee------

Overload. Remove object from the weighing pan.
Out of range or unstable error. There is a load beyond the zerorange at the power-on. When pressed the RE-ZERO key orpowered on, unstable weighing shows this display either.
Low battery. Replace batteries with four new ones immediately.
Calibration error. Unstable weighing or incorrect calibration weight.
Internal errors (# shows an error number). Request service.

CALIBRATION
When is Calibration Required?

Calibration switch

Calibration may be required when
the scale was initially installed or
has been moved to anotherlocation.
Calibration
switch cover

Calibration Using a Calibration Weight
Step 1 Press the Calibration switch while the scale is in the weighing mode.
Then, Cal
will be displayed.
Step 2 Press the RE-ZERO key and Cal 0g will be displayed.
With nothing on the weighing pan, press the RE-ZERO key.
Step 3 The display shows Cal
blinking while waiting for the weighing
value to be stable. When becoming stable, the scale perform zero
calibration and will show Cal100g (factory default) with tens place
digit blinking).
Select the next step as follows: Proceed to the span calibration of Step 4.
 Press theON:OFF
key to finish the procedure without
performing the span calibration.
Step 4 At the display Cal100g , place the calibration weight 100 g (±2 mg)
on the center of the weighing pan and press the RE-ZERO key.
 To use the other calibration weight (50 g or more recommended),press the UNITS key to change by 10 g and place the weightequal to the displayed value.
Step 5 The display shows Cal
blinking while waiting for the weighing
value to be stable. When becoming stable, the scale perform spancalibration and will show end. Remove the calibration weightand press the ON:OFF key to finish the procedure.

Gravity Acceleration Compensation
The scale is calibrated with the gravity acceleration value 9.7985 m/s2
at the factory. When the gravity acceleration at your location isdifferent value, you should calibrate the scale using a calibration
weight. But if the calibration weight cannot be prepared, change thegravity acceleration of your scale to the value of the area where thescale is used. See “The Value of Gravity Acceleration at Various
Locations” of this manual.
Step 1 Start from Cal
display at the Step 1 of “Calibration Using aCalibration Weight”, and press the UNITS key and the current
acceleration value will be displayed. ex. 9.7985
Step 2 Press the RE-ZERO and the digit that can be changed starts toblink. Change the value with following keys.
RE-ZERO key To increment the blinking digit.
UNITS key
To move the blinking digit.
Step 3 After setting the new value, press the RE-ZERO key whilepressing the UNITS key. Then, the display will show end
fora second and stop blinking the value. Press the ON:OFF key tofinish the procedure.

Restoring the Calibration Data
The zero calibration, span calibration and gravity acceleration values
can be restored to the factory default values.
Ex. The scale was calibrated with wrong weight, but there is nocorrect weight. The values above can be reset to the factory default.
Step 1 Start from Cal
display at the Step 1 of “Calibration Using aCalibration Weight”, and press the UNITS key twice to display
Clr.
Step 2 Press thePress theRE-ZERO
RE-ZERO

key, then the display will show Clr no .
key again to display Clr go to restore.

Step 3 At the display Clr go , press the RE-ZERO key while pressing
the UNITS key. Then, the display will show endfor asecond and automatically return to Clr.
Press the ON:OFF key to finish the procedure.
 If perform the step 3. to the display Clr no , the display will
return to Clr
without showing end.
