:DCIRcuit command
:DCIRcuit <b>
[:SENSe[1]]:FRESistance:DCIRcuit <b> Toggle dry circuit (low voltage ohms)
Parameters <b> = 1 or ON Enable dry circuit (low voltage) ohms
0 or OFF Disable dry circuit (low voltage) ohms
Query :DCIRcuit? Query status of dry circuit (low voltage) ohms
Description This command is used to enable and disable dry circuit (low voltage) ohms
for low resistance measurements. Dry circuit testing limits the voltage across
a component under test to 20mV or less. This low voltage prevents the
puncturing of oxidation on switches and relay contacts. Dry circuit ohms is
supported only for the 10 and 100 ohm ranges of 4W ohms.
:OCOMpensated command
:OCOMpensated <b>
[:SENSe[1]]:RESistance:OCOMpensated <b> Toggle offset compensation
[:SENSe[1]]:FRESistance:OCOMpensated <b> Toggle offset compensation
Parameters <b> = 1 or ON Enable offset compensation
0 or OFF Disable offset compensation
Query :OCOMpensated? Query status of offset compensation
Description These commands are used to enable and disable offset compensation for two-
wire (RES) and four-wire (FRES) low resistance measurements. Offset
compensation is used to cancel the effects of offset voltages (such as thermal
EMFs) when making resistance measurements.
Although measurements can be made on any valid resistance range up to and
including 100MΩ, offset compensation only has an effect on the 10kΩ and
below ranges.
