• Press the P, S key and release it repetitively in order to select required function. The
(W), (VA) or (cos ) indicator has to light up.
• Connect tested appliance to test socket 1.
• Press the START key; measurement starts to run (see chapter 4.1. for measurement
control details). Measurement is indicated by the (START) indicator.
• Switch on tested appliance’s mains switch and put it into operation.
• Finish measurement after displayed result is stabilized (see chapter 4.1. for
measurement control details).
• After finishing of measurement (the (START) indicator turns off) the last measured
value is displayed. You can check other measured quantities – press and release the P,
S key repetitively.
• Switch off tested appliance’s mains switch.
4.8.2. Power consumptions and cos  measured by means of current clamp
It is important to observe these principles for proper measurement:
• Both REVEXplus and tested appliance must be powered from identical
phase.
• Current clamp must enclose live conductor in a way that arrow on current
clamp points from power source to appliance. Mains outlet from which
the instrument is powered has to have live contact located on left side. If
apparent power value or cos  value fluctuates randomly and even values
out of specified measuring ranges are displayed then reverse either
clamp’s or mains plug’s orientation.
