1.4 Battery instruction
1. . when you use the internal battery first time，you should charge
the battery fully, to prevent low voltage resulted from self leakage
of battery.
2. when the “red” light flash means low battery, pls. charge it in
time3. the light turns to red during charging
4. when the light turns to green, means fully charged.
5. if battery is not used for long time, take it out to avoid the
leakage.
6. In order to keep the battery in best using condition, it is suggest
that you fully discharge the battery every month, the method is that
using the indicator till it is automatically power off.

2.Installation and calibration
2.1 Power supply connection
The indicator is powered by adapter, you plug the adapter directly into
the “DC” pin at the back cover the indicator is ok.
2.2 Connection of load cell and indicator
The indicator can connect with 6 load cell of 350Ω at most, 4 wire or 6
wire load cell both ok.
There are two methods connection between load cell and indicator
A. quick disconnect, as below:
B. Terminal trip connection (inner connection)
1. the exciting voltage for the load cell is 5VDC, the largest output
current 120mA, maximum connect 6 pcs 350Ω load cell;
2. Load cell (or the signal cable for the junction box) is connected
with 5 bit
Terminal trip ( J3) on the circuit-board of weighing indicator.
3. Open Weighing indicator back cover, insert signal cable to the
terminal trip(J3), and make sure the screw is fixed tightly, the
connection as below:

Technical parameters:
Resolutions: 1/1000
Outside Load: 100-350Ω
Connection:
1. Inside connection: 4-20mA, load input port connect with “I” of J2, Ground port
connect with “ GND” of J2
2. Outside connection: 4-20mA, load input port connect with “1” pin of DB9,
Ground port connect with “6” pin of DB9
Testing :

7
Connect the 250Ω to the 4-20mA, adjust the multimeter to the current stalls, the
red pan connect the loading port, and the black pan connect” GND” to test the
output current.
Calibration:
1. Press” Print” and “ Total” go to C32, show[out-4], the output current should be
4mA.
2. If Press [↑]show[out-5]，Pres[↓]show[out-20]，the output current should be
20mA.
3. Adjust the current, for example, adjust to [out-20], the output current should be
12mA, if not 12mA. Press [←](“Zero” key)or[→](Net/gross key)to adjust the current
to 12mA
2.5 Relay output signal function
The indicator can output 4 signal , connect with the outside equipment
the indicator can perform automatic control function and upper limit
and lower limit alarm function. Perform the 4 kinds function through
setting C33, 4 signals
