grounds unless you have no choice. An independent ground stake
usually works better than a common ground.
Select Direct Clip-on, which turns on the transmitter output at the lead
jacks. In LO-F, adjust the power output selector arrows to increase the
power to a visible level on the bar graph (Not Applicable to HI-F). As a
rule it is best to start tracing with a low level signal indicate
d by an “OK”
near the power output bar.
If you can’t achieve the minimum “OK”
indication, turn the unit off and retry your grounding operation
above
. A good ground is crucial for optimum operation. Soil conditions
can affect this and you may wish to moisten the grounding area. You
can increase the output power with the adjustment arrows in order to
increase the range and depth of the trace, but this is will reduce battery
life in proportion. In HI-F mode, select the power level 1-4 that gives you
the best response.
Electing ‘DIRECT HI-F’ or ‘DIRECT LO_F’ operation
: When in the Direct
Clip-on mode it is also possible to choose between two signal
frequencies best suited to Long-and-Deep (LO-F) tracing or Short-and-
Shallow (HI-F) tracing. You may need to experiment with the use of
these two methods to get the best results for your application.
WARNING
–
Do not touch the metal red or black alligator clips on
the transmitter cords when the power is on. There is danger of
injury or death should this occur.
BROADCAST OR CLAMP: When using one of the two connectionless
modes,
select “Broadcast or Clamp” from the Home screen. This turns
on transmitter power to the Broadcast antenna in the bottom of the
case. The case then can be positioned over a wire or metal pipe to
induce a tracing signal in it. If the Inductive Clamp is plugged in to the
front panel in this mode it becomes the active antenna and can be used
to induce tracing signals on many wires and pipes by clamping the jaws
around the target.
