The Find and Fix mode assists the operator in locating the leakage
source through numeric and audible alarm indicators. As your dis-
tance from the leakage point increases or decreases, the numeric
indicator on the bottom-right of the screen changes to reflect the
leakage level. The graph scale on the left side of the screen is
controlled by the peak value, and displays the current leakage level in
relation to the peak value. When the leakage level meets or exceeds
the alarm threshold, an audible alarm is triggered. The alarm rate will
increase as you move closer to the leakage source.
The Find and Fix mode uses the antenna type, leakage distance, and
compensation features established in the Measure mode. When you
want to change the parameters of these features or obtain a more
accurate measurement of the leak, press the softfkey to return to
the Measure mode.

Reflections can sometimes increase or decrease received strength.
Be sure to move the receiving antenna toward or away from the
suspected source to obtain the maximum signal reading.

You can freeze the leakage measurement at any time by pressing the
SHIFT +
keys. Notice that the mode icon in the upper left-hand
portion of the screen flashes when the measurement is on hold. Press
the SHIFT +
keys again to release the hold. The measurement is
not retained when another mode is selected or the CLI-1450 is shut
off.
