Functional Checks
9.1
Locator Health Check
Leica Geosystems accepts no responsibility for maintenance and calibration
conducted by unauthorised persons.

If the depth reading deviates from known depth of the test utility or
if an error code is displayed, return the locator for service.
9.2
Locator Functional Check
Before any tests can be carried out it is vital to check the status of the unit, its
batteries and basic functionality.
The following list is used to achieve this.
1. Inspection
•
Casing:
The casing should be free of significant damage.
•
Labels:
Body labels must be legible and intact. Display label must be free
of damage and tears.
•
Battery hatch:
The hatch must lock into place.
•
Battery holder:
All the battery contacts and springs on the holder must
be free of corrosion and the holder in good condition.
•
Battery contacts:
The battery contacts must be free of corrosion.
Once the general condition of the Locator is established the Audio Visual test
can be performed.
2. Audio/Visual display test
Upon depressing the trigger the Locator should test the display and speakers
by illuminating each segment in the bar display, the mode and function indica-
tors and depth display, the battery indicator light will illuminate throughout the
display test. All LCDs must be operative and an audible output must be heard.
3. Battery/Functional self check
If there is no response when the trigger is activated or the low battery illumi-
nates (or flashes) after the Audio / Visual display test, the batteries will have to
be replaced. Use alkaline batteries. Replace all of the batteries at the same
time.
The purpose of the following procedure is to verify the performance of the
Locator. It is important that the test is conducted away from areas of electro-
magnetic interference or over buried services with a large signal radiating off
them.
1.

2.
Whilst in Power mode hold down the i Button, until the settings are
displayed.
3.
