OPERATION AND USE
1. Turn the unit on in an uncontaminated / gas free
environment by moving the switch from the “OFF”
to the “ON” position.
2. The green ready LED will illuminate if there is
ample battery power. The red LED may icker and
the tick may sound during the warm up. To silence
the tick, rotate the tick wheel fully counterclockwise.
3. Adjust the “TICK ADJUST” by rotating it in a
clockwise direction until a uniform tick begins to
sound. A uniform tick rate indicates a fully warmed
up instrument. The red LED will ash at the same
time the tick sounds.
4. Approach suspected leak areas with the sensor
until the tick begins to increase. When the tick
increases do not move the sensor from the
suspected leak area, rotate the tick adjust slightly
counterclockwise to slow the ticking sound and
continue to approach the leak. Continue to use this
method to pinpoint the leak.
REMEMBER: An increase in tick indicates you are
approaching a leak, a decrease in tick indicates you
are moving away.
