Total Run Time (m:s)
You can then set the voltage and duration of each of the 10 steps. The total duration of the measurement (Total
Run Time) is calculated by the instrument.
The adjustment range of the voltages is from 40 to 15,000V.
The duration of the steps ranges from zero or 0:01 to 99:59. If a duration is set to zero, the time displayed is -:--.
A duration below 30 seconds is not very useful because acquiring a stable resistance result requires some time.
If either a step voltage or a step duration is set to zero, the step will be set to zero as a whole and will be skipped
during the test.
