Measurement Time and Resolution

The table below lists the measurement time configuration options available
for the multimeter, for each measurement function.

DC, Resistance and Temperature Measurements

For dc voltage, dc current, resistance and temperature measurements
only, the multimeter allows for two ways to set integration time, both of
which affect the measurement resolution. These are in the number of
power–line cycles (NPLCs) and aperture.
Using NPLCs sets the number of power line cycles, during which the
multimeter's analog–to–digital (A/D) converter samples the input signal for
a measurement. The multimeter automatically detects the AC line
frequency, using it and the NPLC selection to set integration time.
Selecting a larger NPLC value yields better resolution; a shorter value
provides for faster measurements. Choices are 0.001
0.06, 0.2, 1, 2, 10 or 100 (PLCs).
