Hazardous AC Voltage Warning
The 500XP is not an AC mains power detector.
This warning
feature is included only as an aid to safety. This product is not
intended to be used with AC mains power but should indicate if
near a hazardous AC voltage.
Available in selected programs of the 500XP only (not 500FP),
the acAlert
®
feature is important in the filtered modes where
there is little hum from the loudspeaker. Should AC at 50 Hz
or 60 Hz be detected, the probe will rapidly flash the red and
green LEDs alternately and generate a “booop-(audio)-booop”
warning sound. Pair tracing tones can be heard during the
pauses. The warning tone may be overridden for 30 seconds by
pressing both buttons while the tone is being generated.

tions. The chosen setting is stored in non-volatile memory.
