Configuring for Highest Accuracy Measurements

The measurement configurations shown below assume that the internal DMM is in its
Factory 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
• Set the input resistance to greater than 10 G
• Use 4-wire ohms and enable offset compensation for the best resistance accuracy.
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.
