1. SAFETY PRECAUTIONS

All safety message
the following:

˜W ARNING

CAUTION

When using the scale/balance, the following safety precautions should always be followed.

˜ WARNING

Use only the AC adaptor with the scale/balance. Other adaptor may cause damage. (AC adaptor is
optional)

˜ CAUTION

Avoid installing the scale/balance in direct sunlight; this may cause discoloration or malfunctions.

Do not mix the type of batteries. Replace all other batteries at the same time.

If the scale/balance is not to be used for a long period of time, remove all batteries from the battery
compartment to avoid leakage which may cause damage to the instrument.

s are identified by the following the words "WARNING" and "CAUTION". These words mean

Important information to alert you to a
situation that might cause serious injury
and damage to your property if
instructions are not followed.

Important information that tells how to prevent
damage to equipment.

Avoid overloading that could cause damage to the scale/balance.

Do not drop water in the scale/balance that is not water-resistant. It causes damage, if inside of the
scale/balance is wet.

Matter charged static electricity could influence the weighing. Discharge the static electricity. As example, the
method is to use the electrification prevention spray, to spray it to both side of weighing platform.

2. Setting up the scale/balance

&AUTION!!

Avoid installing the scale/balance in
scale/balance on a firm weighing table so that the scale/balance is level. (The scale/balance will not perform
accurately when it is not level.)

Place the scale/balance on the firm surface that is flat and level for an accurate weighing.

4. WEIGHING

Before weighing

Whenever possible, please allow the balance to warm up for 10 minutes after first turning to power on, so that
the balance will function. Properly and accurately.

Error messages

EEEE: Overload

: Low battery

Calibration may be required before weighing.
Read "CALIBRATION" first and if necessary, calibrate your scale/balance for accurate weighing.

Weighing procedures

1. Press [ON/OFF] to turn on the scale/balance.

When power is turned on, all display segments appear on LCD for a few seconds and finally "0" will appear on
the display.

2. Select the weighing unit with [UNIT].

5. CALIBRATION

When to calibrate:

When first installing the balance, the factory will still be valid, of course. However, if it is exposed to severe
environmental conditions such as dust, contamination, high humidity, a re-calibration can be mades. The
common calibration intervals should also be adhered to (e.g. annual re-calibration according to ISO).

How to calibrate:

1. The scale must be turned off.

2. Press and hold the [Unit] k

mode and display a random number such as 0247581811, which is tha indication of A/D converter (the signal of
the weighing sell). When loading the scale, this number should increase and when removing the load, it should
decrease and stabilise. Now press [UNIT] key to confirm the zero point. The weighing platform should be free from
any load. The display will show "00SAVE" for a short time and go to the first calibration point "2000.0"
(PCE-BS 3000) or "200.00" (PCE-BS 300). Now load the scale with the 2000 g weight. Then press the [Unit] key
again. The display will show "00SAVE" again and then go to the second calibration point "3000.0". You can either
cancel the calibration by pressing the [ON/OFF] key or load the scale with a 3000 g weight and press the [Unit]
key again. "00SAVE" will be displayed for a short time. The two-point calibration is now completed and the display
will again show the signal of the A/D converter.

The calibration is complete.

FUNCTION SETTINGS

Enter function setting mode.
Press [ON/OFF] to turn the power off. Press [ZERO] first, then press [ON/OFF], while keeping [ZERO] pressed,
the display will show A_ON or A_OFF.
