Signal Generator
pre-2003 model
10. Set the Signal Generator to full power. Return the
‘Pulsed/Continuous’ switch to the ‘up’ position (continuous)
and the ‘Loud/Mute’ switch to the ‘up’ position (loud)
in preparation for Connected Mode Checking.
11. Press the ‘M’ button on the Function Checker.
Repeat until ‘Con’ is shown on the Function Checker display.
12. Plug the Direct Connection Leads (red and black) into the
socket on the Signal Generator and attach a crocodile clip
to each terminal on the Function Checker.
CORRECT RESULT
: The audio response should change to a
lower pitch as the second crocodile clip is attached to the
second terminal. The Function Checker bar graph should
show an indication of 1/3 full scale and the ‘33kHz’ icon
should show in the top left hand corner on the Function
Checker display.
NOTE
If the CORRECT RESULT is not achieved, the cause may be a set of faulty Direct Connection Leads.
Replace with good leads and try the test again.
