Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low voltage is detected, the display will alternate between displaying ohms and volts. When displaying ohms, the flag over the symbol will be visible. When displaying volts, the flag over the ‘V' will be visible. When the voltage magnitude is sufficient to impair the accuracy of the ohms measurement, only voltage will be displayed. If the voltage is AC, a sine wave will be visible on the display [T--4]. If a high AC voltage is detected, a rapid beeping tone will be heard.

3.Press the Trace [T-3] repeatedly until the desired frequency appears on the display.

4.Press Output [T-5] to select high output level for longer tracing distances or deep pipe/cable.

Dyna-Coupler Method

1.Connect the Dyna-Coupler to the transmitter output jack [T-6] using the coupler cable (9011).

2.Clamp the Dyna-Coupler around the cable or pipe, below any bonds, just before it enters the earth. The jaws of the coupler must fully close.

3.Press Trace [T-3] to turn on the transmitter. Press again to select 8 KHz, 33 KHz or 133 KHz.

Note: When using a Dyna-Coupler, always select high output level by pressing the output key [T-5] on the transmitter.
