3M 2273 manual Selecting Passive Power Frequencies, Selecting Auxiliary Frequencies

Page 13

Selecting Passive Power Frequencies

See section Initial Receiver Configuration (Page 3) to set the power frequency to 50 Hz or 60 Hz. The Receiver can be tuned to locate 3 different harmonics of the chosen power frequency.

H50 Hz or H60 Hz (high harmonic): Best for general locating of passive power.

L50 Hz or L60 Hz (low harmonic): Works best on primary power cables. May be used when high harmonic is weak or erratic.

100 Hz or 120 Hz: For locating rectified AC power signals, often found on pipelines using impressed current cathodic protection.

When a Power frequency is selected, the Hz symbol will flash, indicating that alternate frequencies are available. To change the selected power

frequency, press and hold then press to select the next Power frequency.

Selecting Auxiliary Frequencies

Auxiliary frequencies are used to trace cables without using frequencies supplied by the 2273 transmitter. The Receiver may be able to detect these auxiliary frequencies, depending on the model:

31kHz: For locating in-service CATV cables.

512, 560 Hz or other frequencies for locating cables connected to a remote location transmitter with that frequency.

If your Receiver has multiple auxiliary frequencies, the Hz symbol will flash when one is selected. To change the selected auxiliary frequency,

press and hold then press to select the next auxiliary frequency.
