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:

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

For example:
Check weigher application. Connect indicator with yellow, green, red 3
lights. Yellow light on when overload, if ok the green light on. If
underload red light on. And can connect with buzzer. There would be
alarm remind when overload.
C33=2 Feeding control application
For hopper scales. The target is between is 50~500kg, the Output
card can perform open and close feeding valve.
Parameter setting C13=500kg C14=50kg
C13=500kg upper limit , close feeding valve
C14=50kg lower limit, open feeding valve.
Connection: 1. Connect directly control machine, pls. connect OUT 4,
suggest connect another manually switch as the stop switch in
emergency
2. indicator output signal will influence the ON/OFF switch to control
machine, OUT 2 ON, OUT 1 OFF, OUT 3 connect buzzer, alarm
remind when start and stop.
Instruction: when the weight over 500kg, OUT 1 OU3 instant
connection and break off, OUT 4 break off; when weight under

Power on & off
Press 2 seconds to power on or power off, after power on the
indicator show”000000-999999”. After self inspection. It go to the weighing
mode. Pls. check it whether 6 bits LED/LCD display and the status light is
good or not.
3.3 Zero operation
1. Initial zero setting
When power on the indicator, if the weight on the scale is within the
initial zero tolerance, indicator show zero automatically.
2. Manually Zero setting
When the scales is stable, and not the negative display, you can zero
the weight within tolerance by press keys.
3.4 Tare operation

13
Press “TARE” key, the gross weight is tared, indicator show the Net
weight, the “Net” “tared” status light is on. At tare mode, Press” TARE”
key, clear the tare weight, the indicator will show the gross weight.
3.5 Accumulation operation
At Zero mode, load weight till stable, Press go to accumulation
mode, ”Total” light on, display” n 001”, and then display loaded weight; unload
the weight , back to zero, load the second weight again till stable. Press
display”n002” then display the second loaded weight. Repeat it agin
and again, maximum 999 times.
Check the accumulation
Press “ON/OFF “key and hold it then press “TOTAL”” key, display ”n**”, (it is
the accumulating times) then show total weight. there are 8 digits totally. It
shows the first 4 digits then the last 4 digits. For example, the first 4 digits
is”0012”, the last 4 digits is”34,56” It means the actual weight is “1234.56”
EXIT the accumulation function
When the indicator show the last 4 digits, Press hold it, the
indicator show “ clr n”, it means don’t clear the total Weight, Press “PRINT”
key to exit it; if you want to clear total weight, Press “ZERO” or “TARE” key,
“clrn” change to “clry” it means clear total weight ,then Press “PRINT” to clear
the total weight and exit accumulating mode.
3.6 Print
If the weighing is stable, after connect with printer, press” PRINT”
can print the weight. Note: at tare mode, print with tare. if negative
weight,, can not print. Set C30 for time format.

There are two different hold function. Peak hold function and data hold
function.And the setting is different accordingly.
C11=3 Automatic hold function C11=0 close hold function.
3.8 COUNT
1.At weighing mode, load the weights on the platform scales, Press”
Count” the indicator show” PCS 0” press” Zero” key input the quantity,
press” Print” to confirm it
2 . Load the goods on the platform scales, then the indicator will show
the quantity.
3. Press” Count” back to weighing mode.
4. If you want to weigh different goods, at weighing mode, put the
sample on the platform scales, press” Count” the indicator show”0”
Press “ Count” hold it and then press “ ON/OFF” the indicator show”
