integration time in power line cycles (PLCs) also sets the aperture time and the
resolution. For example, 16 PLCs (60 Hz line frequency) sets an aperture time of
267 ms. The corresponding resolution depends on the function and range you
select.

•
The greater the number of PLCs, the greater the normal mode rejection (and the
lower the reading rate).
•
Only the 1 PLC and 16 PLC settings provide normal mode rejection of 50 Hz or
60 Hz power line related noise.
