Apparent Power + Reactive Power Measurement - HP 850F Operating Manual

when it is over than that. The maximum range is 1800kW of three phase
sum of active power, 9999 will be displayed when it is over than that.
7. Press MAX/▲ , the display shows MAX, it starts recording the
maximum active power value. Press again to display the current active
power value.
8. Press MIN/▼ , the display shows MIN, it starts recording the minimum
active power value. Press again to display the current active power value.
Note
● When there is no input or single phase, the Meter displays 9999.∑
button is not valid.
● It can only sum up the current measurement value. The maximum and
minimum value cannot be summed up.
● Only at this range can carry out sum of watts measurement, other
ranges cannot carry out this measurement.
● When testing has been completed, disconnect the connection between
the testing leads and the circuit under test and remove testing leads from
the input terminals.
D. Apparent Power (main display) + Reactive Power (secondary
display) Measurement.
To avoid damages to the Meter or harms to you, do you measure
higher than AC voltage 600V rms and AC current 1000A rms.
Warning
1. To test for Apparent power (main display) + Reactive power (secondary
display), connect the Meter as follows: Press the MENU to select Apparent
power (main display) + Reactive power (secondary display) range.
2. Press the lever to open the transformer jaw, and clamp them to the
corresponding phase of tested conductor. If user needs to measure any
phase of the 3 phase, then clamp them to that phase's conductor.
3. The connecting method of 3 phases 4 wires, 3 phases 3 wires or single
phase 2 wires, see figure 6, 7 and 8
4. When measuring 3 phase 4 wires:(see figure 17, 18, 19)
● Press SELECT to choose the first phase A, see figure 17.
