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 the 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 Transmitter (2273E only). The Receiver may be able to detect these auxiliary frequencies, depending on the model:
LF: General VLF locating
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 the 
then press 
to select the next auxiliary frequency.
