Indication Meaning
3101.x Version number of software
dc x.xx The voltage of battery is x.xxV
Err-00 Load cell wiring error or AD error
Err-01 Calibration switch is not short while calibrating
Err-02 Counting mode, under sampling

3
Err-03 When calibration, the placed weight is too small and it refuses to calibrate.
(Weight should more than 10% max. capacity)
- - - -
Overload, show this as the weight over 100%FS+9e, with the DING sound.
Then you should reduce the weight.
4. Operations
4-1 Power on and Power off:
①Power on:
Press <ON/ZERO> key, It displays software version after “DING” sound, and then dc-x.xx (voltage of battery
is 3~4.2V), self-inspection, 9,8,7···1,0, and the “zero” lamp lighting. Now it’s in working state.
②Power off:
Press <OFF> key to power off.
③Auto power off:
It will be auto power off after 10 minutes when scale is in at ZERO and with no operation.
④Low voltage off:
It will be auto power off when the voltage is too low.
4-2 Calibration
1. Switch on the adjust key（the adjust key is in the indicator）.
Press <ON/ZERO> to power on .
2. Press <SET/0~9> and <ON/ZERO> 3 seconds at the same time.
It shows the last capacity. For example: c-60 means 60kg.
Press <SET/0~9> to choose c-30, c-60, c-100, c-150,c-200, c-300,c-600,
c-1500, c-3000, c-6000 （c is capacity and unit is kg）
3. Press <TARE> to do tare action.
4. Now it displays internal number 0. If it is not 0, press <ON/ZERO> to zero.
5. Place more than 10% max. capacity standard weights on plate.
Press <TARE> to input the value of weights after internal number is stable.
Press <SET/0~9> to add 1. Press <TARE> to input next value till to finish.
And then it shows CAEnd for 1 second and return to weighing.
(Please attention to the place of decimal point when inputting values)
6. If display Err03, it means calibration fault.

4
The reason is: weights are too small or input wrong value.
4-3 Zero
When without tare, the weight display is ≤4% Max. capacity. Press <ON/ZERO> and the display
shows “ 0 ”, ”ZERO” Lamp lighting.
4-4 Weighing
Put weight to pan, and it shows the weight, lamp lighting.
4-5 Tare
Put a container on plate and press <TARE >, it shows 0 and ”ZERO” lamp off. Then ”TARE” lamp
lighting. Put the weight on container and it shows net weight. Remove the weight and container
together, it displays negative tare and “ZERO” lamp lighting. Now press <TARE > and it returns to
normal weighing.
4-6 Power saving
Show “0” with auto power saving after 40 seconds. Put a weight to start weighing again.

Put the plug in the socket, is charging lamp. is lighting when charging.
Show voltage：after power on and on“0”, at the same time press <ON /ZERO> and <TARE > three seconds,
now show the battery voltage, press <SET/0~9> to exit.
4-9 Parameter setting
Press <SET/0~9> for 3 seconds to enter setting and show main menu. Press <SET/0~9> to choose
continuously. It displays as bellow:
rAngE (set limit)
UnItS (choose unit)
A-OFF (choose auto power off)
FILt (set display mode)
Zero (set auto zero)
bUZZE (set buzzle)
d (choose division)
LU- (brightness adjusting)
4-9-1 rAngE (set upper and low limit)
4-9-1-1 When it shows rAngE, press <TARE> to set limit values. Press <SET/0~9> to choose ON or OFF.
“ON” is start limit function. “OFF” is Exit limit function. Press <TARE> to confirm.
4-9-1-2 When choose “on” , Press <tare> to enter to set limit value. “under” lamp is lighting and max figure is
blinking. Press <set/0~9> once to add numbers. Press <tare> to confirm. When finishing setting under
values it will auto exit and then set “over”(same as set under limit).After finish setting, it will back into
weighing.
4-9-1-3 When low limit > high limit, it displays off, and then exit.
4-9-1-4 Alarming indicate: m is the weight.
When m≥high limit, “over” lamp is lighting and flickering.
When low limit <m<high limit, “accept” lamp is lighting (not flickering).
When m≤low limit, “under” lamp is lighting.
Caution: when the display is not stabilization, no lamp lights.
4-9-2 Units
4-9-2-1 when it displays units, press <tare> to enter and press <set/0~9> to change units. Then press <tare>
to confirm. Units: h9(kg), pcs(counting), lb.lb (decimal pounds)

6
4-9-2-2 Counting: when it displays “pcs”, press<tare>. Now “pcs” lamp lighting.
Longtime press <on/zero>, it displays count and return to 0. Then put the sample (as much as possible, but
don’t more than max.capacity). After stable, press <tare>. Press <set/0~9> to add values and press<tare>to
choose. After finishing, it display pcs and pcs lamp lighting.
