5. Because of the meter's detection limit, a line ( or conductor) under test
may be electrically live even if the buzzer does not sound, the red LED
does not flash and the display does not indicate the presence of
electric field.
6. Before and after each use, verify the meter's operation by detecting a
known AC voltage. Do not use the meter if it operates abnormally or
malfunctions.
7. To avoid electric shock, do not touch any conductor with your hand or
skin.
8. To avoid interference, don't perform non-contact ac voltage detection
in an environment with strong electromagnetic field; otherwise the
detection result may be wrong.

To disable the automatic power-off feature, turn the rotary switch from "
