nication
Frequency range: 32768 ± 30 Hz
This is an active mode – the signal, which the DIGICAT detects, must be impressed onto the
service by a DIGITEX.
Used to trace and identify metallic services, by impressing a distinct signal onto the service,
allowing it to be traced above ground. The 33 kHz signal provides a greater locating inter-
ference rejection than 8 kHz, but with increased cross coupling (leakage of signal from one
service to another).
Only available with DIGICAT 200.
33 kHz is the only mode used to obtain depth measurements. When the depth function
button is pressed and released, line mode is selected and will display the depth to the centre
of the line being traced. If a sonde is being used, the button should be pressed and held,
this will display the depth to the sonde. The depth reading is displayed for five seconds.
Only available with DIGICAT 200GIS.
1. When the depth reading is displayed, press and release the depth function button, the
display will indicate "LOG".
2. Press and release the depth function key again to activate the wireless data link and
export the data to a compatible wireless computing device.
