C.Scope Signal Generator:
Function Checks
Battery Condition
- Select Continuous. Good batteries will be shown by a loud clear audio tone. Bad batteries give an
interupted audio tone. On the SG-V the display will show at least one solid segment if the batteries are ok.
Induced Mode
- This can only be checked in conjunction with a C.Scope Avoidance Tool as described on previous page.
If the unit does not meet the results required, repeat the test with another C.Scope Cable Avoidance Tool to determine
whether the Signal Generator is suspect.
Connected Mode
- Set the minimum output level, insert the connection lead and the long earth lead and then
connect the red lead to the long earth lead to create a short circuit. The pitch should change to a low tone.
The leads should be arranged to create an open loop on the ground of approximately 1m diameter. Check that a signal
can be detected by the Cable Avoidance Tool (in Generator Mode) when pointed closely at the loop.
Depth Measurement (XD Model Only)
- An area of services, metal structures, etc should be chosen (beware of
reinforced car parks). A search with the C.Scope Cable Avoidance Tool in all 3 modes will help confirm the absence
of other services. An insulated cable or wire 20m+ (not supplied) is laid out on the ground surface and the far end
connected to a ground stake and earthed. The near end is connected to the red Connected Mode lead.
NOTE These checks DO NOT guarantee full system performance. The Cable Avoidance Tool and Signal Generator
should be returned to the manufacturer or an approved agent for recalibration every 12months.
NOTE If a deterioration in performance is suspected the equipment should not be used. It should be returned to
the manufacturer or an approved agent for checking.
