The following is a list of actions to be taken if the unit is
not working properly:
1). Screen is Blank:
Check the battery is inserted correctly.
Open the battery door on the bottom rear of the unit.
The + and - symbols on the battery should
match the corresponding + and - symbols on
the inside of the battery compartment.
2). Unit does not measure all wires
<1>. Ensure that horizontal distances between wires are
within the sonic beam.
<2>. Check if the unit measuring head is parallel with the
reflecting surface of the object to be measured.
3).Incorrect readings:
<1>. Ensure the measurement mode switch is in the corr-
ect position, MEL for cable height measurement,
and CAL for horizontal distance to object measur-
ement.
<2>. Ensure no walls or similar obstructions are within 2
meters either side of the unit as reflections from these
can interfere with correct operation. Ensure the temp-
erature reading has stabilized.
