Ⅷ.Precautions of Use

Turn on according to the regulations before use, preheat and then
calirate the balance with standard weight. Don’t use the balance in
explosion hazardous environments. If a failure occurs, refer to the
table below:

Stnadard RS232 comminication interface can be optional. Sandard
9-pin RS232 cable can be used to communicate with the computer.
a. Click the “Start”/ “Programs”/ “ Accessories”/ “Comunication”/

“Super terminal” on the computer screen, enter a name, select the
icon, then click “OK”. Just select “Connect using (N): COM1”
and clikc “OK”.
Choose:

1. Baud rate:9600

2. Data bits:8

3. Parity: None

4. Stop bit: 1

5. Data control: Hardware
Then click “OK” , it will display the current weight balance on
the computer.

ⅠKey Functions of Balance

Ⅳ. Calibration

ON/OFF switch key
UNIT unit conversion key
PCS counting key
CAL calibration key
TAR taring & zere setting key

ⅡInstallation of Balance

Place the balance on a flat workbench, shaking of balance, flow and
strong electromagnetic interference should be avoided.

III Turning On

Plug the adapter or install 4 AA batteries(4×1.5vAA battery).Press the
ON/OFF key to display “888888”. After “300.000”displayed, it
enterinto 60 seconds count down of preheating. At last it displays

0.000g. Occurs when the upper-right corner zero “O” symbol, it
means zero has stabilized.

1. Calibration should be taken after turning on and preheating for

10-30 minutes.

2. Calibration:

In the case of the balance doesn’t load any object, press “CAL”
calibration, after 5 seconds it display “—CAL—”, release the key,
later it displays “calibration weight value” is flashing. Now put
the weight that value same with “calibration weight value” on the
pan. After second minutes it displays “calibration weight value”,
remove the weight, the balance return to zero automatically after
dilpays “------” again. Calibration is complete. If still slight error
after first calibration, please re-calibrate according to aboved
process several times or carry out linear calibration.

3. Liner Calibration

In the case of the balance doesn’t load any object, press “CAL”
calibration, after 5 seconds it display “—CAL—”, release the key,
press “CAL”key and don’t release, corresponding linear
calibration values for each sections will display after
approximately 5 seconds. The flashing value means value of
weights shall be loaded, upon loading the displayed value is not
blinking, it means that the balance has memorized segment linear
nominal value. Reomove the weights and wait for next period of

flashing calibration value , then load corresponding weights value,
until the balace return to zero after remove the weights, which means
that the linear calibration is complete.

V. Funtion of Counting

1.Counting
In standby mode of the balance(with the container should be peeled) it
dilplays “0.000”, press the “PCS” key, “10” flashes, the lower right
corner displays “g” convert to “pcs”. If a higher count accuracy
required, in the beginning enter into count mode(displays “10”
flashes), each press “CAL” key there is a value to be set (various
between 10-20-50-100-150-200-250-500), then select a certain
value, put the corresponding object counted, short press “PCS” key, to
enter into the counting function of the value.

2. Short press the “PCS” key to exit the counting functions and restore
the standby mode.

Ⅵ. Unit Conversion

Short press “UNIT” key, it display “ct’, “oz”, “lb”, “tl”, “gn”, “ozt”,
“dwt”, “g” for every press.
