detected, it will be indicated by an increase in the LED meter, and a rushing
sound will be heard in the headset. This sound will become more intense,
and the meter reading will increase as the instrument is pointed closer to the
leak point.
If there is ultrasonic noise in the area and the display is at maximum, or you
hear the hi-pitch beep of the Over Range Audio Alarm, reduce the sensitivity
until the alarm stops and the lights nearly disappear. The display reading is
only for relative measurements (comparisons). Two lights versus ten can
mean two things: either you are far from a given leak, or the leak is smaller
than the one that produces ten lights. Use the sound intensity in the headset
and the varying lights to guide you toward the leak point. Reducing the
sensitivity as you approach the leak will verify that you are on the right path
since the indications will increase in the direction of the leak.
Other Important Information:
Remember to turn off the instrument when you are done using it, or the
battery will run down.
When the battery becomes weak enough that performance may be
reduced, the instrument will provide a visual signal on the display, and a
beep in the headphones, and then the instrument will shut off. The
instrument will not re-start until you insert a fresh new battery. Always use
a good quality 9-volt Alkaline battery (same as used in smoke detectors).
When inserting a new battery the instrument will perform a quick check of
the battery
–
if the battery has adequate charge and is properly installed
there will be a visual signal on the display, and a beep in the headphones.
If this does not happen, and the instrument does not function, then the
battery may be dead or weak, or it may not be properly installed.
When storing the instrument after use, we recommend removing the
battery from the battery compartment, to prevent the instrument from
turning on accidentally, and running down the battery.
