The
Pl-vf 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
G
aIn
uP
and down buttons are used to increase and decrease the gain in small amounts. If the
meter reading is very low, pressing the
G
aIn
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.
