ORDERING INFORMATION
Troubleshooting
The following is a list of actions to be taken if the
unit is not working properly:
Screen is blank
Check to make sure the battery is inserted correctly.
Open battery door on the bottom rear of the unit.
The battery is inserted with the terminals on the
inside. The + and - symbols on the battery should
match the corresp and
-
symbols on the
inside of the battery compartment.
Unit does not measure all wires
Ensure that horizontal distances between wires are
within the sonic beam, as shown in the Performance
section of this manual.
Incorrect readings
Ensure the Calibrate mode switch is in correct
position, i.e. CABLE for cable height measurement,
and WALL for horizontal distance to object
measurement. Ensure no walls or similar
obstructions are within 7 feet (2m) of either side of
the unit, as reflections from these can interfere with
correct operation.
