Offset Compensated Measurements
Offset compensation removes the effect of any voltages in the circuit being
measured. The technique involves taking two measurements, one with the current
source turned on, and one with the current source turned off and computing the
difference. A description of this operation is given on page 284.
– Front Panel operation: Offset compensation is on at power on. Turn offset
compensation off under the 3: OCOMP W command in the MEASure menu.
– Remote operation: Offset compensation is off following a remote reset or
preset. Use the following command to change the state of offset
compensation:
SENSe:
FRESistance:OCOMpensated {OFF|ON}
RESistance:OCOMpensated {OFF|ON}
Low Power Measurements
Low Power measurements use a reduced output measurement current to limit the
power dissipation in the circuit being measured.
– Low Power measurements apply only to 4-wire ohms measurements.
– When the low power measurement mode is enabled, the ‘LP’ annunciator is on
in the display.
– Setting the Voltage Limited measurement mode will cancel the Low Power
mode.
– Front Panel operation: set low power mode under the 4: LOW POWER W
command in the MEASure menu.
– Remote operation: use the following command to set the low power ohms
mode:
SENSe:FRESistance:POWer:LIMit {OFF|ON}
