Operation (cont.)
acAlert™ 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.
Active in all modes, 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 only may be
overridden for 30 seconds by pressing both buttons while the
tone is being generated.
Setup Mode
The configuration of the mains hum and narrowband filters can
be adjusted if required. There are five settings; 1 is the default
that should suit most situations. The chosen setting is stored in
non-volatile memory.
