3. The instrument shows the “
PH1
” message and waits for the
detection of L1 phase
4. Connect red cable to input lead
V
and black cable to
input lead
COM
then position the leads respectively to the L1
phase and the ground reference PE of the circuit under test
(see Fig. 7).

CAUTION
If the frequency of the measured voltage is lower than 42.5Hz or higher than
69Hz, the display shows the message “
F<42.5 Hz
” or “
F>69 Hz
” and phase
detection does not start.
5. When a
voltage
≥
100V
is detected, the instrument emits a
sound signal (buzzer) and the message “
Meas
” is displayed.
Do not press any key and keep the test lead connected to L1
phase cable.
