functions.
ii. LEFT-RIGHT INDICATOR: A multi-segmented bar graph will
appear on the display with the directional arrows to guide the op-
erator to the conductor. In conjunction with the directional arrows,
special tones will come from the speaker.
One tone, which is lower in pitch, corresponds to the conductor
being to the left of the operator. Another tone is higher in pitch
and corresponds to the conductor being to the right of the operator.
When the receiver is positioned directly over the conductor, the
speaker will null (produce no sound).
The VOLUME switch may be used to adjust the loudness as de-
sired.
iii. SIGNAL POWER INDICATOR: SPI numbers will appear on
the display panel. These numbers will range from 0 - 999. As the
operator nears the conductor, the numbers will increase and as
the operator moves away from the conductor, the numbers will
decrease. The numbers are the highest when the operator is nearest
to the conductor and when the receiver is lined up with it (Figure
2-10).
iv. ESTIMATED/CALCULATED DEPTH: The estimated depth indi-
cator provides a continuous reading of estimated depth for a quick,
real-time reading during locating. Unexpected estimated depth
readings alert the operator of potential factors which may affect
locating accuracy. An automatic calculated depth reading super-
sedes the estimated depth reading. Refer to page 29 for Calculated
Conductor Depth Procedure.
