Configuring for Highest Accuracy Measurements
The measurement configurations shown below assume that the multimeter
is in its power
–
on or reset state. It is also assumed that auto–ranging is
enabled to ensure proper full scale range selection.
DC Voltage, DC Current, and Resistance Measurements:
• Select
NPLC
and
100
(NPLCs) for
INTEGRATION
.
• Set INPUT Z to HI
–
Z (for the 100 mV , 1 V , and 10 V ranges) for the best dc
voltage accuracy.
•
Use the 4 – wire ohms function (
W
4W) for the best resistance
measurement accuracy.
• For 2 – wire ohms, dc voltage and dc current measurements, set
AUTOZERO
to
ON
to remove thermal EMF and offset errors.
• Null the test lead resistance for 2
–
wire ohms measurements, and to
remove any interconnection offset for dc voltage measurements.
AC Voltage and AC Current Measurements:
• Set the AC FILTER to 3 Hz: SLOW .
Frequency and Period Measurements:
• Set the GATE TIME to 1 sec .
