184 HP E1312A and HP E1412A Multimeter Specifications Appendix A
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
Ω
(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).
