WARNING
If the frequency of the measured voltage is lower than 40Hz or higher than
70Hz, the display shows the message “
F<40 Hz
” or “
F>70 Hz
” and phase
detection does not start.
3. When a voltage higher than or equal to 100V is detected, the
instrument gives an acoustic signal (buzzer) and the
message “
Meas
” is shown on the display. Do not press any
key and keep the test lead connected to L1 phase cable.

”.
It is necessary to repeat the measuring cycle from the beginning, by
pressing key
F4
(
Go
) and starting from step 1 again.
6. When a voltage higher than or equal to 100V is detected, the
