Step 7
1. Before starting this calibration step, configure the shunt and load (electronic load or resistor load)
as shown in the following table.
Model
Shunt
Electronic load
Resistor load
2280S-32-6
0.05 Ω
Constant current mode
32 V
6.0 A
5 Ω
2280S-60-3
0.05 Ω
Constant current mode
60 V
3 A
20 Ω
2. Enter the measured result from the digital multimeter (DMM) and press the
ENTER
key.
After entering the data, the waiting window is displayed. You need to wait a few seconds for the
internal measurements and calculations. The step 8 calibration window is displayed.

2. Wait for the instrument to take internal measurements and calculations. Measurements are
complete when the Save window is displayed.
3. Press
Save
to save all the calibration constants to system internal memory. If you press
Cancel
,
you will lose all the calibration constants and exit the calibration.
Saving calibration constants from the front panel
1. Press the
Save
soft key. The Enter Date window is displayed.
2. Enter the present date and press the
ENTER
key. The date and calibration constants are saved
to instrument's internal memory.
