5.
Observe the displayed output:
•
PAS
means unit is within set tolerances.
•
ERR
means unit is outside set tolerances and may need servic-
ing.
☞
•
Repeat the test in a different location if the units displays
ERR
.
•
The Locator will automatically repeat the function test if it fails.
•
Repeated failure will indicate a faulty unit, which must be
returned for service.
This test can be carried out provided the depth of a service on the test area is
known.
1.
Switch the Locator on and ensure that it is in 33 kHz mode.
2.
Position the Locator directly over and at right angle to the service.
3.
Press and release the i Button to activate the depth measurement.
4.
Record the depth.
5.
If the depth reading deviates from the normal value or an error code
is displayed, the Locator should be returned for service.
☞
If any of these tests give no response or a significantly differ-
ent response from normal, the Locator should be returned for
service.

Functional Check of the Transmitter
Before you carry out any tests, it is vital to check the status of the unit, its bat-
teries and its basic functionality. To achieve this, carry out the following proce-
dure:
☞
For this procedure, the cable set of the transmitter and a fully
charged battery pack are required.
1.
Inspect the general condition of the transmitter.
•
The casing should be free of significant damage.
•
The cable set should be free of damage to the cable insulation
and clip shrouds. The clips should be free of corrosion.
•
Body labels must be legible and intact.
•
The cover of the battery compartment must lock into place.
•
All the battery contacts and springs of the compartment must be
free of corrosion and the compartment in good condition.
•
The battery contacts must be free of corrosion.
•
The cover of the USB port must be in place and provide the
required environmental protection.
2.
Once the general condition of the transmitter is established,
perform the Audio/Visual test
.
Turn on the transmitter. All LED indicators should light up and the
speaker should emit a tone.
3.
Perform a Battery check.
Observe the Low Battery LED indicator and replace or recharge the
batteries if necessary.
