Command Sequence For Auto Ohms Example; Command Sequence For Manual Ohms Example - Keithley 6430 Quick Results Manual

18 Quick Results Guide
Auto ohms example — Table 11 shows a typical command sequence to use auto ohms to
measure resistance.
Manual ohms example — Table 12 shows a typical command sequence to use manual ohms
to measure resistance. This example uses auto range for current measurements. If you were to
use manual ranging, you should select the lowest possible current range for the measurement.
For example, to measure a 1M resistor with the source set to 2V, the 1µA measure range
should be selected to achieve the best accuracy (2V/1µA = 2M).
