Resistance adjustment
Perform the following adjustment steps (DC adjustment step 6 through step 9):
Figure 173: Resistance calibration
DC adjustment step 6: 100 Ω
1. Send the commands:
dmm.func = dmm.FOUR_WIRE_OHMS
dmm.range = 100
2. Source 100
Ω.
3. Read the resistor value from the calibrator.
4. Send the command:
dmm.calibration.dc(6,(
resistorValue
)) print("done")
Where
resistorValue
is the resistor value read in step 3.
DC adjustment step 7: 10 kΩ
1. Send the command:
dmm.range = 10e+3
2. Source 10
kΩ.
3. Read the resistor value from the calibrator.
4. Send the command:
dmm.calibration.dc(7, (
resistorValue
)) print("done")
Where
resistorValue
is the resistor value read in step 3.
