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 (Ω 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.
