Keysight M9182A/M9183A Calibration and Verification Procedure 23
The following examples illustrate how to calculate the proper values in step 8,
above.
– If the value of the resistor is 10.02000e6 then the value programmed for the 20
μA range is 20e-6 × 10.02000e6 = 200.4 V.
–For the 2 μA range the value programmed is 2e-6 × 10.02000e6 = 20.04 V, and
for the 200 nA range the value programmed is 200e-9 × 10.02000e6 = 2.004 V.
WARNING
Any voltages greater than 42 V may present a safety hazard. Make certain
that these voltages are not accessible.
