Transmitter Keypad and Connector Definitions
OFF: [T-1] Turns unit off and performs battery test.
OHM / FAULT / TONE: [T-2] 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: (2273M units only) In this mode, the transmitter sends
two alternating 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 200 KHz
signals.
TRACE: [T-3] Turns the unit on and places the unit in Trace (Locate) mode.
Cycle through the transmitter frequencies by pressing [T-3] repeatedly.
SELECT FREQUENCY: Press TRACE [T-3] repeatedly to cycle the
transmitter through four frequencies (577 Hz, 33 KHz, 8 KHz, and
200 KHz). The selected frequency will be displayed [T-4]. ‘ALL’ indicates
that all four frequencies are transmitting simultaneously.
DISPLAY: [T-4]
INDICATOR FLAGS:
These flags coincide with the operational mode of
the transmitter. (From top left to bottom right) Fault mode [T-2] (2273M
only), Tone [T-2], Trace (Locate) mode [T-3], Ohm meter [T-2], Voltage (at
start up the transmitter checks for high voltage), and the Output Flag (no
flag = low output; flag = high output; flashing flag = 5 Watt mode).
DIGITAL DISPLAY: Indicates frequency, relative current, resistance, battery
level and voltage.
OUTPUT: [T-5] Cycles output level; normal, high, and 5 Watt (optional).
Normal=No Flag; 3 Watt=Flag; 5 Watt=Flashing Flag
OUTPUT JACK: [T-6] Port for direct connect cables or 3M
™

Dyna-coupler.
EXTERNAL 5 WATT JACK: [T-7] Port to connect cigarette lighter adapter
cable, or rechargeable battery (5 Watt units only).
