Locators: Depth Measurement Function Checks
(DXL4 and MXL4 only)
An area clear of services and metal structures should be chosen (beware of reinforced concrete car parks). A search with the DXL4
or MXL4 in all modes will help confirm the absence of other services. An insulated cable or wire (not supplied) over 20 m (70’) long
is laid out on the ground and the far end connected to a ground stake and earthed. The near end is connected to the red Direct
Connection Lead.
The black Earth Lead should be laid at right angles to the 20 m (70’) cable and earthed at the far end with the Earth Stake.
The plug should be inserted in the Direct Connection Socket of the Signal Generator/ Transmitter.
The Signal Generator/ Transmitter is turned on to the lowest Output Power Level and Continuous Mode. The Locator should then be
held vertically above the longer cable, approximately midway along it and the depth can then be measured. It is best to make a few
readings at different depths.
For MXL4 Locators only, this procedure can then be repeated using 512Hz, 640Hz or 8kHz.
NOTE
These Function Checks are approximate only. If a deterioration in performance is suspected for any reason,
the equipment should not be used. It should be returned to C.Scope or a C.Scope Authorised Service Centre
for more thorough investigation.
