E. Transmitter 2550 Keypad and Connector Definitions
Dynatel TM 2550 | Frequency | | | | |
- + o | on | | | | | |
off | | | Output Level | | |
T-1 | T-2 | T-3 | T-4 | T-5 | T-6 | T-7 |
[T-1] off: Turns unit off and performs battery test.
[T-2] on - Ohm-meter:Turns the unit on and places the unit in Ohm-meter mode. This measures the continuity of the trace conductor/pipe and its far-end ground.
[T-3] on - Frequency: Turns the unit on and places the unit in Trace mode.
Select Frequency: Press Frequency [T-3] repeatedly to cycle through the transmitter's active frequencies (577 Hz, 1 kHz, 8 kHz, 33 kHz, 82 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. Starting from bottom left to upper right; Ohm-meter [T-2], Voltage (at start up the transmitter checks for foreign voltage), Output Level [T-5] (no flag = normal output; flag = high output; flashing flag = maximum output) and Trace mode [T-3].
Digital Display: Indicates frequency, relative current, resistance, battery level and voltage (if present on target).
[T-5] Output Level: Cycles output power 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.
NOTE: 12-watt output level varies by frequency. Output is limited to 10 watts at 33 kHz and 1 watt at 82 kHz and 200 kHz using the direct connection method.
[T-6] Output Jack: Port for direct connect cables or Dyna-coupler cable.
[T-7] External Jack: Port to connect cigarette lighter adapter cable, or rechargeable
battery (2200RB). Input voltage level: 9-18 VDC.
