The mains socket outlet of the measuring cable is marked with a white reference spot.
: the phase is on the right-hand contact of the mains plug when the white spot is up.
L
: the phase is on the left-hand contact of the mains plug when the white spot is up.
L
: the device cannot determine where the position of the phase, probably because the PE is not connected or the L and
PE conductors are interchanged.
The L symbol is displayed as soon as the voltage is high enough (> UL programmable in SET-UP). The terminal identified
as L is the one that has the highest voltage with respect to PE.
3.2.3. ERROR INDICATION
The only errors reported in voltage measurement are values outside the voltage measurement range. These errors are reported
in clear language on screen.
3.2.2. MAKING A MEASUREMENT
Connect the leads to the device to be tested. As soon as the device is powered up, it measures the voltages present on its ter-
minals and displays them, whatever the setting of the switch.
