Probe Battery Test
1. Push the probe's BATTERY TEST and ON buttons at the same time.
2. If the probe's LEDs do not light in BATTERY OK range, change the battery.
Probe Range Switch
1. Range switch determines the probe's gain.
2. If the probe displays 10 LEDs, gain is too sensitive. Turn switch to lower setting.
Test Position (Fig. 1)
1. Connect the transmitter to source of power.
2. Set the probe's range switch to BREAKERS-5.
3. Push ON and wait for it to calibrate.
4. Hold the probe next to the transmitter, observe blinking LEDs and
"chirping" sound.
Identify Circuit Breaker (Fig. 2)
1. Connect the transmitter to a source of power.
2. Set the probe's range switch to BREAKERS-3.
3. Push ON and wait for it to calibrate.
4. Hold the probe's tip to each circuit breaker as shown. The correct breaker
produces the strongest signal. Adjust gain as necessary.
5. In critical areas, remove panel trim and turn the probe's range switch to
WIRES-1. Hold the tip to each wire. The wire with the strongest signal may
be visually traced to the breaker.
Locating Wires In Walls (Fig. 3)
1. Attach pigtail connector to transmitter.
2. Clip one lead to a seperate earth ground such as a water pipe.
3. Clip the other lead to the hot conductor.
4. Set the probe's range switch to SCAN position.
5. Push ON and wait for it to calibrate.
6. Hold the probe's tip close to the wall or floor where you suspect the
conductor is located.
7. Sweep the probe across large areas until the probe's signal locates the
conductor. Adjust range switch as necessary.
NOTE: The same procedure may be used for tracing individual wires in
bundles.
Following Conduit (Fig. 4)
1. Attach transmitter and follow signal as explained in
"Locating Wires in Walls".
2. Adjust the probe's range switch as necessary.
HINT: Since the feeder panel may radiate a magnetic signal to
nearby conduit, make sure the probe is always more than 5'
(1.5 m) away from the circuit breaker box.
