C.Scope Locator:
Function Checks
The CXL2, DXL2 AND MXL2 Locators have an in built Self Test feature that automatically tests the Locator’s circuits
and receiving aerials for correct performance each day (see pages 16–17).
The C.Scope Function Checker product allows further functionality checks to be made of any C.Scope Locators
at any time. It will also check the functionality of C.Scope Generators/Transmitters. If a Function Checker is not
available then the following procedures below can be used.
Locator:
Battery Condition
Check by depressing the On/Off Switch beneath the handle.
The display will show at least two solid segments if the batteries are OK.
Ensure power on tone is heard.
Power Mode
Select Power Mode. Set sensitivity fully clockwise and point the body of the Locator at a fluorescent light from
a distance of one metre. Switch the light on.
A loud tone should be heard and the display should read greater than 50% full scale. Reducing the sensitivity
should cause the displayed reading to reduce and the tone to cut out.
Radio Mode
Select Radio Mode. Set the sensitivity fully clockwise and, from a distance of less than 0.25 metres, point the unit at
a metal conductor of length greater than 100 metres (for example a metal pipe or cable). A warbling tone should be
heard. The display should read greater than 50% full scale.
All Scan Mode
Select
All Scan Mode. Repeat the same tests that were used to function check the Power and Radio Modes.
