Description
Set the Auto Range Low Limit to prevent the instrument from
selecting a range that is lower than appropriate for your application.
Sets the number of digits that are displayed for front-panel
readings. It does not affect accuracy or speed. Refer to
number of displayed digits (on page 3-40).
Set the amount of time that the input signal is measured. Lower
NPLC settings result in faster reading rates, but increased noise.
Higher NPLC settings result in lower reading noise, but slower
reading rates.
Set Auto Zero to On to set the instrument so that it periodically gets
new measurements of its internal ground and voltage reference.
This setting increases measurement accuracy, but may slow
measurement time.
Sets the number of readings that are processed when a
measurement is requested.
instrument is set to measure resistance (SVMR(Ω) or SIMR(Ω)).
Turn this setting on to improve low-resistance measurement
accuracy.
Description
Use the relative offset feature to subtract a set value or a baseline
reading from measurement readings. When you enable relative
offset, all subsequent measurements are displayed as the
difference between the actual measured value and the relative
offset value.
Sets the relative offset value to be applied to measurements.
