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.
