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
manual ranging is enabled to ensure proper full scale range selection.

DC Voltage, DC Current, and Resistance Measurements:

Set the resolution to 6 digits (you can use the 6 digits slow mode for
further noise reduction).

Set the input resistance to greater than 10 G

(for the 100 mV, 1 V,

and 10 V ranges) for the best dc voltage accuracy.

Use 4-wire ohms for the best resistance accuracy.

Use Math Null to null the test lead 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.

Select the slow ac filter (3 Hz to 300 kHz).

Frequency and Period Measurements:

Set the resolution to 6 digits.
