SGA3 Signal Generator Function Checks
Battery Condition
Turn the Signal Generator on. Good batteries will be indicated by a loud, clear audio tone.
Bad batteries give an interrupted audio tone.
Induced Mode
This can only be checked in conjunction with a Locator as described on the previous page. If the unit does not meet
the performance expected, repeat the test with another Locator to determine whether the Signal Generator is at fault.
Connected Mode
Set the minimum Output Power Level, insert the Direct Connection Lead and the 10 metre Auxiliary Earth Lead
and then connect the red lead Crocodile Clip to the Auxiliary Earth Lead Crocodile Clip. The pitch should change
to a low tone.
The leads should be arranged to create an open loop on the ground of approximately 1 metre (3’) in diameter.
Check that a signal can be detected by the Locator in Generator Mode when pointed closely at the loop.
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.
