Configuring for High Accuracy Measurements

The measurement configurations shown below assume that the multimeter is in its power-on or reset state. It is
also assumed that manual ranging is enabled to ensure proper full scale range selection.
DC Voltage, DC Current, and Resistance Measurements:
•
Set the resolution to 6 digits Fast (integration time of 10 PLC). You can use the 6 digits slow mode
(integration time of 100 PLC) for further noise reduction.
•
Set the input resistance to greater than 10G (for the 100mV, 1V, and 10V ranges) for the best dc voltage
accuracy.
•
Use 4-wire ohms for the best resistance accuracy.
•
Use Math Null to null the test cable resistance for 2-wire ohms, and to remove interconnection offset for
dc voltage measurements.
AC Voltage and AC Current Measurements:
•
Set the resolution to 6 digits (integration time of 100 PLC).
•
Select the slow ac filter (3Hz to 300kHz).
Frequency and Period Measurements:
•
Set the resolution to 6 digits (aperture time of 1 second).
