Safety Instruction
For safety operation please follow the safety instruction.
WARNING
Settings, Calibration, Inspection and Maintenance should only be
done by a trained person or staff.
WARNING
Please make sure the indicator has sufficient grounding.
WARNING
The indicator is a static sensitive piece of
equipment. Cut off the power during electrical
connections and internal components touched by
hand are prohibited.
Please take all measure of anti-static protection.

Installation and calibration
Power supply connection
The indicator is powered by A/C adapter that plugs directly into the
“DC” pin at the bottom of the indicator.
Connection of load cell and indicator
The indicator can be connected up to 6 load cell of 350Ω, 4 wire or 6
wire load cell both ok.
Quick disconnect, as below:

Basic operation
Power on & off
Press
2 seconds to power on or off the indicator. After self test
it will go to the weighing mode.
Zero operation
1. Initial zero setting
During power up if the weight on the scale is within the initial zero
tolerance, indicator show zero automatically.
2. Manually Zero setting
When the scale is stable and not the negative weight you can zero the
weight within tolerance by press
key.

Tare operation
During “TARE” operation when gross weight is tared the indicator will
show the Net weight. The “Net” “tared” status light is on. In tare mode,
Press” TARE” key to clear the tare weight and the indicator will show the
gross weight.
Accumulation operation
With Zero on the Display load weight, Press goes to
accumulation mode, ”Total” light is on, display” n 001”, and then the display
goes back to the loaded weight; unload the weight , Display shows zero, load
the second weight again. Press
display”n002” then display the
second loaded weight. Repeat it again and again for a maximum 999 times.
Check the accumulation
Press “TOTAL “key and hold it then press “ON/OFF” key, display ”n**”, (it is
the accumulating times) then show total weight. If the total weight is beyond
the display capability, It will show 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.

Print
If the weight is stable, press” PRINT” you can print the weight.
COUNT
1.In weighing mode, load the Pieces on the platform scales, Press”
Count” the indicator show” PCS 0” press” Zero” key in the quantity,
press” Print” to confirm it
2. Load the goods on the platform scales, the indicator will show the
quantity.
1. Press” Count” to return to weighing mode.
2. 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”
PCS 0”, press “Zero” input the sample quantity, press “Print” to
confirm it. Then repeat the step 2 and 3.
Calibration and Parameter setting
Enter setting
There have two methods to enter the setting menu:
1. when the switch “ CAL” is off, press the “PRINT” hold it and
then press” Total” this enters the C08-39 settings.
2. Take out the sealing screw on the back of indicator, move the
sealing switch to second position. Press “PRINT” hold it and then
press “Total” key this enters C01-C39 settings.
