SECTION 2 SPECIFICATIONS

2.2.4 KILOWATT METER SPECIFICATIONS

True kilowatt metering is provided using the voltmeter and ammeter inputs. Display range and resolution
is XXX.XXX kW. The Remote interface may provide 3 digits of precision (digits to the right of the
decimal point).
Accuracy is ± 1% of full scale over the full range of ambient conditions.

2.2.5 POWER FACTOR METER SPECIFICATIONS

Power factor is displayed as the ratio: kW / kVA. Display range and resolution is X.XXX. The Remote
interface may provide 3 digits of precision (digits to the right of the decimal point).
Accuracy is ± 1% of full scale over the full range of ambient conditions.

2.2.6 FREQUENCY DISPLAY SPECIFICATIONS

The programmed frequency is displayed as an indicator only. Internally, there are 3 frequency ranges,
each with a different resolution. The user need NOT be concerned with changing these ranges as the
UPC performs auto-ranging based on the selected frequency.

2.2.7 WAVEFORM ANALYSIS

(Option: Harmonic Analysis and Synthesis)
The UPC WAVEFORM ANALYSIS function is an optional feature which derives harmonic content values
for any of the output voltage or current waveforms. Harmonics are displayed in tabular form on the front
panel LCD display or may be queried via the Remote Interface. Also displayed is Total Harmonic
content (THD) and individual sums of even and odd harmonics (EHD & OHD). THD is the RMS of EHD
and OHD. The Harmonic analysis function reports both magnitude and phase angle (relative to 0º of
voltage) of each harmonic for metered voltage and current waveforms.
