 Auto zero-setting when switch on the scale.
 Auto zero-tracing.
 Switch among weighing, counting, percentum. Function of choosing Weight range.
 Power supply: AC 220V (±10%) / 50 Hz, 110V/60HZ, DC 4V / 4Ah (Rechargeable battery inside).
 Working temperature range: 0 ℃ ~ +40 ℃/
 Relative humidity: ≤ 85 % RH
Ⅱ. Keyboard instruction:
1. 【Cali.】 To Calibrate the scale when the scale is moved to a different place.
2. 【Mode】 To choose different function model: Weighing, Counting, percentum.
3. 【Unit】 To choose different unit: kg, lb.
4. 【Set】 To choose high and low limits range in weighing model.
To sample the weight in counting and percentum model.
5. 【Zero】 To make the display zero when there’s nothing on the platform but the display is not zero. And press this
key continuously for 2-4 second, the backlight will be switched on or off with the LCD model.
6. 【Tare】 To delete the tare.
7. 【 ↑ 】 To input number.
8. 【Enter】 To make sure.
Ⅲ. Operation:
The scale must to be placed on the stable and flat surface, adjust its four screws carrier pole to horizontal, if demand,
put the special plate, then switch on the power. The scale cannot be used for a long time under tare state or the function of
zero tracing will disappear and the zero will move.
The scale will go into the weighing model after the beginning display. The signals of “Zero” and “kg” set. You may
press【Mode】to choose the three model: weighing, counting, percentum circularly.
Backlight on/off: This just effective in the LCD model. Press【Zero】key continuously for 2-4 second, the backlight
will be switched on or off.
【Weighing mode】
Choosing Unit Function: Press【Unit】to choose the unit between “kg” and “lb”. The corresponding signal sets on display.
Tare Function:
Put the container on the platform. Press【Tare】to make the weight window display “Zero” after the weight is stable. When
the “Tare” signal sets, the weight displays is Net Weight. Remove the weight, the weight window displays negative.
Press【Tare】again, the weight window displays “Zero”. The “Tare” signal disappears.(The range of tare setting: ≤1/3F.S.)
Zero Function: You may press【Zero】to make display zero when the zero moved when in use.(Zero range: <=4%FS, it is
invalid under tare state.)
Setting Alarm Function:

1. High limit setting--Press【Set】to display the set weight high limit and the signal “-HH-” circularly. Press【Enter】to make
sure and set the low limit. Press【↑】to set the number. In the process of inputting the number, you may press【↑】to add 1
on the recent digit. Press【Enter】to make sure of the recent digit and set the next digit. If the digit is the last one you may
press【Enter】to set the low limit.
2. Low limit setting--It will display the set weight low limit and the signal “-LL-” circularly when you begin to set it. The
operation is the same as setting high limit. It will go into the alarm method setting after the low limit setting finished.
3. Alarm method setting—It means in the range alarm when the scale displays “-IN-”. It means out of the range alarm when
the scale displays “-OUT-”. It means no alarm when the scale displays “-NO-”. You may press 【 ↑ 】 to switch.
Press【Enter】to confirm.
Press【Set】to exit from the setting state when in the process of setting. The set value is invalid.
【Counting mode】
Press【Set】to sample weight in the counting model. It displays “SAP X” (X is the sample number).
1.Press【↑】to choose samples number from 10, 20, 50,100 and 200. Press【Enter】to make sure.
2.The weight window displays “LOAD-C” after the sample number is chosen. Put enough number of samples then
press【Enter】to finish sample.
3.There are two instance of unit weight lacking:
E-59
a. When the weight window displays “-LAC-”, it means the unit weight of sample is less than 80% of division. You
still can count but the counting may be inaccurate. The signal will disappear after about 3 seconds.
b. When the weight window displays “-CSL-”, it means the unit weight of sample is not enough at all. Please
press【Set】to re-sample. Press【Enter】to exit back to the counting model.
Press【Set】to exit from the sample state in the process of sample.
【Percentum mode】
1.Press【Set】in the percentum state to display “LOAD-P”. There are two ways to sample:
a. Put enough samples on the platform then press【Enter】to finish sample.
b. Press【Unit】 then the scale displays “000000”. Press【↑】and【Enter】to input the weight value.
2.When the sample weighed less than 0.1% FS., the weight window displays “-CSL-”. It means the sample is not enough.
You should re-sample. Press【Set】to re-sample. Press【Enter】to exit back to the weighing model.
Press【Set】to exit from the sample state in the process of sample.
【Calibration 】
Keep pressing【Cali.】for about 4 seconds. Calibrate after the weight window displays “CAL.”. There are two ways to
calibrate:
1. Full range load: Put enough weight on the platform according to the full scale. Press【Enter】to make sure. Calibration
finished.
2. Random load:
a. Press【Set】, the weight window displays the weight calibrated last time.
b. Press【↑】and【Enter】to input the weight you want to load. Then load the corresponding weight. Press【Enter】to
make sure. Calibration finished.
Press【Mode】to exit from the calibration state in the process of calibrating.
Note:
The high limit and low limit set in the weighing model are saved in the scale. Different unit corresponding to different
alarm range and method. The value inputted by pressing【↑】cannot be more than the full scale.
【Weighing speed setting】

① Press 【Mode】 and【Set】meanwhile during the self-checking process from “99999”to“000000”,then
loose press the two keys when hear the buzzer.
② After self-checking, it will display the current speed“Spd *”， the speed is different according to different
precision, there are 5 level, “Spd 0”is fastest，“Spd 4”slowest，press 【↑】to choose the weighing speed,
press【Enter】to confirm the speed you have choose, and then return to the normal weighing condition.
IV. Alarm indication:

1. The weight window displays “--OF--” with continuously alarm sound when the weight over 100%FS+9d. If the
ADC overflows, the weight window displays “—Adc—”with continuously alarm sound. For these instances, the
weight should be taken away.
2. If the voltage of the battery is low, the weight window displays “—Lo—” while the weight is zero (The weight
display will recover to normal when it is loaded ). Under this condition, you can use the scale in a short time, but
you should plug in the AC plug as soon as possible to recharge the battery. It will display “—AC—”when charge
the battery if the scale is switch off. And there will no display if user charge the battery during usage.
3. The weight window displays “HHHH” or “LLLL” when the zero weight is higher or lower than the permitted
range.
4. When you switch on the scale. The weight window will display “UNSTA” if the scale is not stable. It maybe
because of the platform’s intensity is too low or the platform is shaken strongly.
You may strengthen the platform or avoid the shake.
5. If it display “-SYS-” when you switch on the scale please re-calibrate or send it to repair.
If it display –Set--”, it means the alarm setting is wrong, please reset the alarm value.
V.RS232 transmission method (optional):

1. RS232 setting
Press 【Model】and 【Tare】key when self-testing, loosen two key when hear the buzzer sound and enter the RS232
transmission setting.
（1）Set transmission method
Press the 【set】key to choose the method of:“Stb” = output when stable, “Etb“ = output once when【Enter】key is
pressed, “SEr” = series (continuous output), or “CLOSE” = output disabled. Then press【↑】key to select method or
press 【Enter】to confirm and set the next parameter.
E-59
(The default mode is“close”.)
Stb ↑ Etb ↑ SEr ↑ CLOSE ↑
print once when stable Transmit continuously Disable the transmit

Press 【Enter】to send
(2) Baud rate Setting

Press【↑】key to select the desired baud rate among “1200”“2400”“4800”“9600”, then press【Enter】to
confirm the selection and exit setting.
（The default baud ratio is 2400.）
↑ ↑ ↑ ↑
9600 4800 2400 1200
2. RS232 interface
(1) Frame format
The scale have a standard RS232 UART signal, Each data frames has 10bits.The detail information of frames is as
follows：
bit1 bit2 bit3 bit 4 bit 5 bit 6 bit 7 bit 8 bit 9 bit 10
bit1：start bit
bit2~bit9：data bit
bit10：stop bit
(2)Data format：Every message include 6 bytes, they are following:
No. 1: D0~D7 —— 0FFH（Message Flag）
No. 2: D0~D2 —— Decimal point（0-5）
D3~D4 —— Current mode: 00 - weighting; 01- counting; 10 - percentum;
D5 —— 1 means weight is negative, otherwise is positive
D6 —— 1 means weight is stable, otherwise is unstable
D7 —— 1 means weight is overflow, otherwise is normal
No. 3: D0~D7 —— BCD1（ LSB）
No. 4: D0~D7 —— BCD2（MSB）
No. 5: D0~D7 —— BCD3（HSB）
No. 6: D0~D7 —— Unit for weight: 1 - lb; 0 - Kg;
