8. Check the correct operation of the Sensitivity Control by adjusting
it first fully clockwise (maximum sensitivity) and then fully
anti-clockwise (minimum sensitivity).
CORRECT RESULT
: The Locator bar graph should change
from showing a full-scale response when on maximum
sensitivity to no response at all when on minimum
sensitivity.
NOTE
If the bar graph does not drop to zero when on minimum sensitivity it may be due to background electromagnetic
signals. Refer to the ‘Selecting a suitable location’ section on page 8.
9. Rotate the Sensitivity Control so that the bar graph
shows a mid-scale response with the audio tone sounding.
Slide the Locator along the side of the Function Checker
to find the position of maximum signal, re-adjusting the
sensitivity, if necessary, to keep the indication at mid-scale.
CORRECT RESULT
: The Sensitivity Control should now
be at a rotation of approximately a one-quarter turn
from minimum.
NOTE
It is important to NOT adjust the sensitivity setting of the Locator or to move it from this position for the
remaining tests.
