FREQUENCY INDICATOR - When a dot appears to the left of a given frequency, that frequency is active
in the receiver and the transmitter. When the receiver operates in the sonde mode two dots will appear,
one to the left of the "Passive" legend and one to the left of the sonde's operating frequency. See Section
VII: Sonde Operation, for additional information.
NOTE: In the passive mode the transmitter is not active. However, a dot next to the "Passive" indicator on
the LCD means that the transmitter has successfully received the command to go "inactive".
DIRECTION INDICATOR - The purpose of the arrows and center bar in this indicator is to tell the
operator in which direction to move the receiver in order to be directly over the target.
Right Arrow - Receiver should be moved to the right to get closer to the target.
Left Arrow - Receiver should be moved to the left to get closer to the target.
BOTH ARROWS and BAR - Receiver is placed directly over the target. This
is also accompanied by a beeping sound.
NOTE: When all three elements of this indicator are OFF, the signal strength is not adequate to make
a directional determination. Keep searching based on the signal strength indication (see below) and
the audio feedback, until one of the arrows comes ON. Directional indication is not available at 455
kHz.
NUMERIC DISPLAY - The numeric display consists of 3 ½ digits (the half-digit can only be a "1" or be
off) and it is used to display signal strength, depth, and transmitter output current.
Signal Strength
- This is an indication of the relative signal level detected by the receiver and is a
function of the gain setting. Good signal strength will typically be between 20 and 80, however see
also Section III - Operation - "Gain", for a better understanding on how to interpret the signal strength
readings.
Depth Reading
- When measuring depth the word DEPTH lights up above the numeric display. Then,
after the calculation is done, the depth of the target in feet and inches (or meters) is displayed
as shown below for as long as the button remains depressed, or for just a few seconds if the button was
pressed and released:
12 4 or (factory set) 4.10
FT IN m
Transmitter Ouput Current
- If the transmitter is in conductive mode and operating at 575 Hz, 8 kHz,
or 82 kHz frequency, the transmitter will measure the amount of current being deliverd through the
conductive clip when the “SHOW STATUS” switch is depressed. Then, upon receiving the next status
request from the receiver via the remote link, the transmitter will send the value of the current
measured in mA (milliamperes). This value will be displayed momentarily on the receiver’s display.
NOTE: There is no current measured for Passive, any of the clamp modes, any of the inductive mode
frequencies or the conductive mode at 455 kHz.
