W of the rotary switch) will be shown. To select the desired function the F key must be
pressed repeatedly until the required function is selected.
Active power measurement
In this function the measurement of the active power together with the measurement of
the power factor are shown on the screen. If the load is inductive, the symbol will
appear on the screen and if the load is capacitive, the symbol will appear on screen.
In this function, the position of the voltage terminals and the jaw is taken into account; the
red terminal should be connected to the line terminal and the jaw should be connected in
such a way that the current flows in the direction indicated on the jaw toward load. In this
mode, data retention and registering of maximum and minimum values is possible by
using the H key.
