alarms at different frequencies.
Note :

Voltage may still remain in the absence of any indication. The
operator shall not rely on non-contact voltage detector to check the
presence of voltage. The detection operation may be affected by
various factors, including socket design, insulation thickness and
type.

When the voltage is input into the meter's input terminal, the voltage
sensor LED may be on as a result of induced voltage.

External sources of interference (like flashlight and motor) may trigger
non-contact voltage detection.
