Set-up
Press 1(Correlate on start-up) Toggles between YES and NO. If set to YES, the control unit
will go straight to the correlate screen after turning on. If set to NO, the control unit will go
straight to the Main Menu after turning on.
Press 2(Default filters) Toggles between CLEAR and RETAIN. If set to CLEAR, in survey
mode, the filters will clear each time a new correlation is processed. If set to RETAIN, in
survey mode, the filters will retain a set filter setting (set by the user) for every correlation
processed.
Press 3(Survey mode range) Toggles between 0.8, 2.4 and 4.0 seconds. Each of these
values provides the time delay range over which the correlator will correlate, where the times
in seconds shows twice the range. For example, over longer distances the 4.0 second range
should be used to give +2 seconds to –2 seconds. If entering pipe data, the survey mode
range automatically defaults to the appropriate setting.
Press 4(Correlation sensors) Toggles between the pairs of sensors to be used. Red-Blue,
Red-Yellow, Blue-Yellow, Base-Red, Base-Blue and Base-Yellow.
Press 5(Radio Mode) Toggles between HIGH power and LOW power. LOW power can be
used over shorter distances and HIGH power over longer distances or areas where a signal
can be interrupted by the environment. The correlator will always default to LOW power when
turning on.
