[T-1] off: Turns unit off and performs battery test.

[T-2] on: Ohm-meter / Tone: Turns the unit on and cycles through the following commands when pressed repeatedly.

Ohm-meter:Measures the continuity of the trace conductor/pipe and its far-end ground. It is also used to measure the fault resistance to earth.

Tone: In the tone mode, the transmitter generates 577 Hz and 200 kHz signals. [T-3] on: Trace (frequency): Turns the unit on and places the unit in Trace mode.

Select Frequency: Press Trace [T-3] repeatedly to cycle through the transmitter’s active frequencies (577 Hz, 8 kHz, 33 kHz, and 200 kHz). The selected frequency will be displayed [T-4]. ‘ALL' indicates that the following active frequencies are transmitting simultaneously: 577 Hz, 8 kHz, 33 kHz, and 200 kHz.

[T-4] Digital Display:

Indicator Flags: These flags coincide with the operational mode of the transmitter. (From top left to bottom right) Trace mode [T-3], Tone mode [T-2], Ohm-meter [T-2], Voltage (at start up the transmitter checks for foreign voltage), and the Output Level Flag (no flag = normal output; flag = high output; flashing flag = maximum output).

Digital Display: Indicates frequency, relative current, resistance, battery level and voltage (if present on target).

[T-5] Output Level: Cycles output level; normal, high and maximum.

Normal=No Flag; High=Flag; Maximum=Flashing Flag (indicated in Digital Display [T-4])

NOTE: An external 12-volt power source is required to obtain Max Output level (12 watts for 12-watt transmitters and 5 watts for 5-watt transmitters).
