6. * Connect the "LOAD" to the terminals of 3-17, 3-18, (Fig. 2)
* Connect the "Power Source" to the terminals of 3-16, 3-19 (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 and Current function is the true rms measurement
*
For the Watt measurement, the max. input current should be less than
AC 10 A.
Line frequency (Hz) measurement:
8. During the Watt measurement, push the "cos
φ/
PF/Hz Button" (3-9, Fig. 1) once,
will show Line Frequency value instead of the PF value.
*
Push the "cos
φ/
PF/Hz Button" again, the Hz value will disappear and the PF
value will display again.
7.2. AC VA/V/A/PF/Hz Measurement
All the measuring procedures are same as the above "7.1-AC Watt/V/A/PF/Hz"
measurement, except you 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 and Hz, it
can not show the value of PF (Power Factor).
7.3. AC Watt Hour (Whr) Measurement
All the measuring procedures are same as the above "7.1-AC Watt/V/A/PF/Hz"
measurement, except you should push the "Watt/VA/Whr Button" (3-7, Fig. 1) twice,
then the display will show the Whr value along with the elapsed time.
* The Whr (Watt Hour) is the value of Watt x hour
* The Whr measurement will start at the moment after the Whr unit is displayed on
the LCD-Display
* The display of Whr measurement will stop (hold) when pushing the "Data Hold
Button" (3-11, Fig. 1) once. Push the "Data Hold Button" once again for
continuing the Whr function.
*
Press “Whr Zero” button (3 – 8, Fig.1) once will “reset (zero)” the Whr
measuring value and make the new measurement again.
