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 :

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
