6) * Connect the " LOAD " to the terminals of 3-17,
3-18, refer Fig. 2.
* Connect the " POWER SOURCE " to the
terminals of 3-16, 3-19, refer Fig. 2.
7) Power on the " Power Source " of the measured
installation.
The " LCD display " ( 3-1, Fig. 1 ) will show the Watt,
Voltage, Current, PF ( Power Factor ) at the same time.
* Watt function is the true power ( V x A x PF )
measurement.
* Voltage & Current function is the true rms measurement.
* For the Watt measurement, the max. input current
should less than ACA 10A.
Line frequency ( Hz ) measurement :
8) During the Watt measurement, push the " PF/Hz Button "
( 3-9, Fig. 1 ) once, will show Line frequency value
instead of the PF value.
* Push the " PF/Hz Button " again, the Hz value will
disappear & the PF value will display again.
5-2 AC VA/V/A/PF/Hz Measurement
All the measuring procedures are same as the above " 5-1
AC Watt/V/A/PF/Hz Measurement " except should push the
" WATT/VA/Whr Button " ( 3-7, Fig. 1 ) once, then the
display will show the VA, voltage, current, Hz at the same
time.
* The VA function is the apparent power ( V x A )
measurement.
* During the VA measurement, the LCD will show
VA, Voltage, Current & Hz, it can not show the
value of PF ( Power Factor ).
