Measurement of Active, Apparent and Reactive Power; W,VA, VAr
The current path be measured directly (up to 10A maximum; up to
16A briefly for a maximum of 30 seconds) or with the help of current
transformers or current clamp transformers. The meter automatically
selects the range which allows for the highest possible resolution of the
applied quantities.
NOTE:
If the meter activates a measuring range which is too high during
automatic measuring range selection, this may be due to peak value
monitoring. Check the crest factor of the respective signal in Volts AC or
DC or Amps AC or DC.
Significance of the Power Factor:
±1: no phase shifting -(0 to 0.99): capacitive; +(0 to 0.99) inductive
• First disconnect supply power from the measured circuit or the power
consumer, and discharge any capacitors.
• Set the rotary function dial to W/PF.
• You can switch the display back and forth between active, reactive
and apparent power with the
Select button
(including power factor).
• The extreme values can be displayed by pressing the
MIN/MAX button
