Step 3
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
2281S
5.05 Ω
Constant current mode
1.5 V
0.001 A
300 Ω
2. Enter the shunt value and press the
ENTER
key.
3. Enter the measured result from the digital multimeter (DMM) and press the
ENTER
key.
4. After entering the data, the waiting window is displayed. You need to wait a few seconds for the
internal measurements and calculations. The step 4 window is displayed.
Step 4
1. Before starting this calibration step, configure the shunt and load (electronic load or resistor load)
as shown in the following table.
Model

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. Then the
Save
window is displayed.
3. You can save the calibration results or continue to the next calibration step. For the details on
saving, see
Saving calibration constants from the front panel
(on page C-19). If you want continue
the calibration, press the
Next
soft key.
