related measurements would be blanked including W, VA and PF.
Select Disable or Enable using the keys and press to confirm.
Averaging
Normally disabled, select Enable to allow the PM1000+ to average results.
Averaging depth is set at four when enabled. All results, including harmonic
magnitude and phase, are averaged except for ranges (when selected for
