[T-1] off:
Turns unit off and performs battery test.
[T-2] on: Ohm-meter / Fault Locate / 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.
Fault Locate:
(2273ME units only) In this mode, the transmitter sends two
alternating locating frequencies (577 Hz and 33 KHz) as well as fault signals 10 and
20 Hz.
Tone:
In the tone mode, the transmitter generates 577 Hz and 133 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 the frequency of the
transmitter (577 Hz, 8 KHz, 33 KHz, and 133 KHz). The selected frequency will
be displayed [T-4]. ‘ALL' indicates that the following frequencies are transmitting
simultaneously: 577 Hz, 8 kHz, 33 kHz and 133 kHz.
[T-4] Digital Display:
Indicator Flags:
These flags coincide with the operational mode of the transmitter.
(From top left to bottom right) Fault mode [T-2] (2273ME units only), Tone mode
[T-2], Trace mode [T-3], 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 Maximum Output level
(12 watts for 12-watt transmitters and 5 watts for 5-watt transmitters).
[T-6] Output Jack:
Port for direct connect cables or 3M Dyna-coupler.
