Power/Energy Measurement On Three Phase Balanced System - HT HT4020 Manual De Instrucciones

4.3.9. Power/Energy measurement on three phase balanced system

Fig. 12: Use of instrument for power/energy measure on three phase balanced system
1. Select the "W3" position
2. Open the jaws and clamp the L3 phase cable. Pay attention to the alignment marks
(see § 4.1.2. and Fig. 12)
3. Insert the red plug into V/ jack and the black plug into COM one
4. Connect the red test lead to L1 phase conductor and the black test lead to L2 phase
conductor (see Fig. 12). The measured active power value is displayed
5. If the symbol "
instrument's full scale. Therefore the power and power factor values could be incorrect
6. By pressing the
capacitive C, inductive I), apparent power (kVA), power factor (Pfi or Pfc for inductive
and capacitive respectively) are displayed
7. Press and hold the ENERGY key for at least 1 second to active the energy
measurement mode. By pressing the
(kWh), reactive energy (kVA
TIME with indication of energy measurement duration are displayed
8. Press the ENERGY key to activate the energy measurement. The message
"MEASURING" appears at the bottom of the display. Press the ENERGY key again to
stop the energy measurement, the message "MEASURING" disappears from the
display
9. For HOLD and MAX/MIN/AVG features refer to § 4.2.1 and § 4.2.3
10. Press ENERGY key for at least 1 second to escape this mode going back to power
measurement function

The maximum input for Voltage measurements is 600V. Do not attempt to
take any voltage measurement exceeding the limits indicated in this manual.
Exceeding the limits could cause electrical shock at the operator and
damages to the clamp meter.
