Function Checks
The CXL4, DXL4 and MXL4 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 12-13).
If you wish to carry out additional checks or to test the Locator’s functionality more than once a day
then the following procedures can be used:
Battery Condition
Check the Locator battery condition 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 base of the Locator at a fluorescent light
from a distance of 1m (3’). 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 0.25m (10”),
point the base of the Locator at a metal conductor of length greater than 100 m (330’), for example
a metal pipe or cable. A warbling tone should be heard. The display should read greater than 50% full scale.
