UTE9800+ Series Smart Digital Power Meter
Window 1: the measured value of voltage, the unit is V.
Window 2: the measured value of current, the unit is A.
Window 3: the measured value of power, the unit is W.
Window 4: the measured value of power factor (PF) or frequency(Hz), it can be switch by press【PF/HZ】key.
3.3.2 Crest Factor
Press【CF】key to enter crest factor display interface, as shown in the following figure.
Window 1: the measured value of voltage crest factor, no unit. The measured value of voltage crest factor=
Voltage crest value/ TRMS Voltage. When no voltage signal is input, it displays "-----".
Window 2: the measured value of current crest factor, no unit. The measured value of current crest factor=
Current crest value/ TRMS Current. When no current signal is input, it displays "-----".
Window 3: the measured value of power, the unit is W.
Window 4: the measured value of power factor (PF) or frequency(Hz), it can be switch by press【PF/HZ】key.
3.3.3 Total RMS of Harmonic
Press【RMS】key to enter the total RMS of harmonic display interface.
Notes: If press【RMS】key multiple times, the system switches between the TRMS display interface and the total
RMS of harmonic display interface, please select the appropriate interface. The following figure is the total RMS
