3M Dynatel 7550 Series User Manual

78-9000-5020-0 Rev C 11
Active Frequencies:
7550 577 Hz, 1 kHz, 8 kHz, 33 kHz, 82 kHz, 200 kHz
7550E (International) 577 Hz, 1 kHz, 8 kHz, 33 kHz, 82 kHz, 133 kHz
ALL indicates that the following active frequencies are transmitting simultaneously:
7550 577 Hz, 8 kHz, 33 kHz, 200 kHz
7550E (International) 577 Hz, 8 kHz, 33 kHz, 133 kHz
[T-4] Digital Display:
Indicator Flags: These ags 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 (no ag = normal output;
ag = high output; ashing ag = 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=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.
[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.

[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: 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 two frequencies simultaneously:
7573 577 Hz and 200 kHz signals.
7573E (International) 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 through the transmitter's
active frequencies. The selected frequency will be displayed [T-4].
