The PATHFINDER PLS
r
eceiver
provides the operator with a direct measurement of the
r
eceiver
’
s
signal strength. The measurement is displayed with three numerical digits (ex:
485
) located at the
top of the LCD display. The measurement range is from 0 to 999 indicating a very week signal
(0) to a very strong signal (999). Absolute Signal Strength is independent of the GAIN setting
or meter reading. It gives the operator information about the actual amount of signal being
radiated from the conductor and received by the
r
eceiver
.
Measuring Absolute Signal Strength at any time is done by reading the number at the top of the
LCD display. The Absolute Signal Strength will not be displayed if the meter reading is too high
or too low. Adjust the GAIN to move the meter reading to mid-scale. The numerical display will
change from
‘---’
to a valid measurement.
Absolute Signal Strength measurements are more sensitive to signal changes than the meter
display. PEAKS and NULLS can be more precisely pin-pointed. This measurement can also be
used to monitor signal loss as the conductor is being traced.
The GAIN up and down buttons are used to increase and decrease the gain in small amounts.
If the meter reading is very low, pressing the GAIN up button will center the meter reading to
mid-scale. Likewise, if the meter reading is very high, pressing the GAIN down button will center
the meter reading to mid-scale.

In this mode the unit will display directional arrows to the
conductor. The audio indicator will provide a solid tone
on one side of the conductor and a pulsed tone on the
opposite side of the conductor. When the unit is centered
in the electromagnetic field the tone will null and the depth
will briefly display at the top of the LCD. This mode is gain
independent.
The Left/Right arrows operate off of the Null reading and will
have the same error rate as the Null locating mode. By utilizing
the Left/Right arrows with the absolute signal strength reading
the user can simultaneously locate with both Peak and Null
modes, thus quickly identifying the match or discrepancy
between the Peak and the Null reading.
