DC adjustment step 8: 100 kΩ
1. Send the command:
dmm.range = 100e+3
2. Source 100 kΩ.
3. Read the resistor value from the calibrator.
4. Send the command:
dmm.calibration.dc(8, (resistorValue)) print("done")
Where resistorValue is the resistor value read in step 3.
DC adjustment step 9: 1 MΩ
1. Send the command:
dmm.range = 1e+6
2. Source 1 MΩ, then read the resistor value from the calibrator.
3. Send the command:
dmm.calibration.dc(9, (resistorValue)) print("done")
Where resistorValue is the resistor value read in step 2.
DC current adjustment
Make the connections as shown, then perform the following adjustment steps (DC adjustment step 10
through step 14):
