Controls
The receiver has several unique features, controls, and indicators with which the
operator must become familiar (Figure 1-4).
1. DISPLAY: This display provides the operator with information concerning
the location and depth of the conductor being traced. A variety of informa-
tion is displayed.
a. Signal Power Indicator (SPI) - The SPI provides the operator with a
dual purpose numerical readout of the relative signal strength of:
1. A normal (active) tracing mode signal using the transmitter.
2.
conductor. The transmitter is not used in this mode.
The readout will display from 0 - 999. As the operator gets closer
to the intended conductor, the numbers increase and as the opera-
tor moves further away from the intended conductor, the numbers
decrease.
b. Left-Right Indicator - The left-right indicator readout is a multi-seg-
ment bar graph with directional arrows that indicate the direction to the
intended conductor.
As the operator approaches the conductor, the multi-segment bar graph will
shorten, and, as the operator moves further away from the conductor, the bar
graph will lengthen.
When the receiver is positioned directly over the intended conductor, the
right and left bars and arrow will disappear from the display, but the LOCK
indicator will remain on.
c. Battery Status Indicator - Continuous readout appears in 20% incre-
ments of battery capacity.
d. On/Off Volume Switch - This switch has two purposes in the receiver.
First, it turns the receiver on. Once on, repeated pressing of this switch
will step the speaker to successively higher volumes (3 levels total) and
then put the receiver in a power off mode where “OFF” is shown in the
display.
**NOTE**
THESE SPI NUMBERS ARE RELATIVE AND DO NOT BEAR ANY SIMI-
LARITY TO NUMBER SYSTEMS USED ON OTHER MODELS. FOR
EXAMPLE, READINGS OF 164, 285, ETC., REPRESENT SUFFICIENTLY
STRONG SIGNALS FOR LEFT-RIGHT AND DEPTH READINGS.
