Chapter 5. Set Up
5-1. Calibration
Adjust weight balance between “Real weight” on the load cell(Weight Part) and “Displayed weight of
Indicator”. When you replace LOAD CELL or Indicator, you have to do Calibration process once again
5-2. Test Weight Calibration (span Calibration) –Mode 1.
- Applicable model : DN500N,510N,520N,530N,540N series
Prepare at least 10% of Max. capacity of your weighing scale.
Step 1. Enter Calibration Mode
Step 1. Enter Calibration Mode
Turn on the Power + with pressing display
Press key display
Press key to start “Calibration Mode”.
Remarks : Go to next step with save key / Back to previous step key
Step 2. Digit(Division)setting ( display)
Press key and stop the optimal Digit value.
(Whenever pressing key, digit value will be changed, like 01-02-05-10-20-50)
Press key and save change and move to next step.
Step 3. Max. Capacity Setting ( display)
Input Max. Capacity of Scale with No. keys.
Input Capacity and press key, and move to next step.
※Caution
(Max. capacity value / division value) can not be over 30,000.(as Indicator resolution is 1/30,000).

Step 4. Zero Balance setting ( display)
Make empty the scale part, and press key.
Indicator check the current Zero balance and save the value and move next step.
Step 5. Span value calculation (   )
Input prepared Test weight value with No. keys.
And press key.
Then, display will show and then, load prepared test weight unit on the scale.
After a few seconds(to remove the vibration effect), press key.
Then, indicator will calculate Span value and move the next step.
※Caution
For the precise Span calibration, please prepare Test weight unit, at least 10% of Max. capacity
of Scale.
Step 6. Check Span Value and Finish the Calibration( )
Check the Calculated Span value.
And after 3sec, will displayed automatically and move to weighing Mode.

Step 4. Measure/Adjustment optimal Zero balance of Scale ( display)
Make empty the scale part, and press key.
Indicator check the current Zero balance and save the value and move next step.
Step 5. Input the Rate Output (mV/V) value of load cell
Input Max. Output Rate(mV/V) value of load cell with No. keys.
- Under this step, input Max. Output rate(mV) of load cell.
- If you installed a few pieces of load cells, the connection will be parallel, so the rated output of
a few load cells are as same as single load cell’s rated output.
-The Output rate is stated on “Calibration certificate” or “Label”
And press key.
Step 6. End Calibration and Auto Reset
- Calculated Span value will be displayed and automatically reset and move the normal
weight indicating mode.

display Zero.
For this compensation function, indicator will estimate the weight
difference is over the set range during fixed time period.
If there is large weight difference over set range within fixed time
