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 259.
• Front Panel operation: Offset compensation is on at power on.
Turn offset compensation off under the 3: OCOMP Ω 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 Ω command in the MEASure menu.
• Remote operation: use the following command to set the low power
ohms mode:
SENSe:FRESistance:POWer:LIMit {OFF|ON}
