If no cable or sensor unit or a defective cable is
connected to the display unit, the warning “no sensor”
appears on the display when the display unit is switched
on: Establish a correct connection between the display
unit and the sensor unit.
If the word “over” appears on the display, the
permissible measurement range of +/- 50° was
exceeded. This measurement range is sufficient for
practical application.
If three dashes appear on the display, the sensor unit is
being used in a position for which it was not calibrated.
After switching off the power the last measured reading
is written to the internal memory of the display unit.
When it is switched on again this reading appears in the
bottom line of the display. This facilitates the comparison
of identical horizontal alignment of the left and right PA
system.
