SELECT button is pressed to select a new frequency. In that case the LED corresponding to the new
frequency will light up GREEN while the SELECT button is pressed.
NOTE: To conserve battery power, and because of the fact that the RF link allows the information the user
needs to know about the transmitter to be displayed on the receiver's display, the LED's are relatively dim,
especially under bright lighting conditions. Usually a hand shade is all that is needed to adequately see the
LED's.
REMOTE - The single indicator in this section is labeled "Link". It will glow GREEN every time a
successful "status request" is received from the receiver. It will glow RED when more than 20 seconds
have passed without receiving a successful "status request" from the receiver.
FREQUENCY - One of the five (5) indicators in this section will glow GREEN to indicate the current
operating frequency.
STATUS/MODE - There are four (4) indicators in this section providing information about the operating
mode and status of the transmitter battery. They are:
CONDUCTIVE/CLAMP
- This LED will glow GREEN when the conductive clips or an optional
inductive clamp is plugged into the jack (see Transmitter Jack section), and the transmitter is not in
passive mode.
OUTPUT POWER
- This LED provides a rough indication of how good a circuit the transmitter is
hooked to, by attempting to measure the impedance range. It is only meaningful when the transmitter
is in conductive mode, ignore it in any other operating mode. It will glow as follows:
GREEN when the circuit is very good, which typically means the impedance is below 2 kohms;
GREEN & RED, alternating when the circuit is of medium quality, which typically means the
impedance is between 2 and 4 kohms.
RED when the circuit is poor, which typically means the impedance is higher than 4 kohms.
NOTE: If the indicator is RED or alternating GREEN & RED, you should try to improve the
connection (check the cables, the clips, the ground stake, wet the ground, clean rust or dirt, etc.).
However, in many cases the reason for the high impedance is the soil itself (sandy or very dry) and/or
the composition of the pipe or cable you are trying to trace (cast iron pipes, rusted or broken wires,
heavy insulation to ground, etc.), and you may not be able to improve the connection. This DOES NOT
MEAN that you won't be able to locate, it just means that there is a smaller amount of current
circulating in the circuit and you may have to increase your receiver gain, or not be able to trace the
signal as far as you would with a higher current.
NOTE: If the transmitter is in conductive mode and operating at 575 Hz, 8 kHz or 82 kHz frequency,
the current measurement feature can provide a better indication of how good a circuit the transmitter
is hooked up to. See Receiver/LCD Display/NUMERIC DISPLAY and Transmitter/Controls/SHOW
STAUS sections, as well as Section III: Operation & Accessories for additional information on the
current measurement feature
INDUCTIVE
- This LED will glow GREEN when there is nothing plugged into the transmitter jack
and the transmitter is NOT in Passive Mode Therefore the transmitter is emitting its signal via the
built-in induction antenna.
BATTERY
- This LED will glow GREEN when the battery is fully charged. It will glow RED when
the battery has a medium charge, and it will flash RED when the battery voltage reaches a level where
the batteries must be replaced. Always replace the transmitter batteries when this LED is flashing
RED. It is not necessary to press “SHOW STATUS” to see this LED.
