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.
