Details 

This command sets the amount of time that the input signal is measured. 

The amount of time is specified as the number of power line cycles (NPLCs). Each PLC for 60 Hz is 
16.67 ms (1/60) and each PLC for 50 Hz is 20 ms (1/50). For 60 Hz, if you set the NPLC to 0.1, the 
measure time is 1.667 ms. 

The shortest amount of time results in the fastest reading rate, but increases the reading noise and 
decreases the number of usable digits. 

The longest amount of time provides the lowest reading noise and more usable digits, but has the 
slowest reading rate. 

Settings between the fastest and slowest number of PLCs are a compromise between speed and 
noise. 

If you change the PLCs, you may want to adjust the displayed digits to reflect the change in usable 
digits. 

The measurement time can also be set as an aperture time. Changing the NPLC value changes the 
aperture time and changing the aperture time changes the NPLC value.
