[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.
[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).
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 (indicated in
Digital Display
[T-4])
NOTE: Output is limited to 3 watts at 577 Hz, 8 kHz, 33 kHz and 1 watt at
200 kHz using the direct connection method.
[T-6] Output Jack:
Port for direct connect cables or Dyna-coupler.
