H. Using the Tone Tracing Probe
The Pro210F tone probe included in the Pro48K kit is used to
receive the tone signal from the Pro48 multi-function irrigation
tester (it is not included if you purchased just the Pro48). The tone
receiving function is turned on by holding down the black button
on the unit top. The Pro210F has a bright LED headlight that
comes on when the button is down.
The volume control is located on the right side of the probe. Adjust
it to a level appropriate to your surroundings and comfort. Rolling
the control forward increases the volume.
Pressing the main button, move the probe near the wire or wires
you are trying to identify. The wire that emits the loudest signal is
the one connected to the Pro48. If the tone seems obscured by
other noises, briefly lift and re-press the main button to enter the
Noise Filtered mode.
A strong signal will cause the front signal LED to glow green. If the
probe battery is low, the battery LED will glow red.
