OPERATIONS
1. Turn the unit on in an uncontaminated
environmentbymovingtheswitchfromthe
“OFF”tothe “ON” position.
2. The green ready LED will illuminate if
thereisample batterypower. TheredLED
may flicker and the tick may sound during
the warm up. To silence the tick, rotate
the tick wheel fully counterclockwise.
3.Adjustthe “TICKADJUST”byrotatingit
inaclockwisedirectionuntila uniform tick
begins to sound. A uniform tick rate indi-
cates a fully warmed up instrument. The
redLED will flashatthesame time the tick
sounds.
4.Approachsuspectedleakareas withthe
sensor until the tick begins to increase.
When the tick increases do not move the
sensor from the suspected leak area, ro-
tate the tick adjust slightly counterclock-
wise to slow the ticking sound and con-
tinue to approach the leak. Continue to
use this method to pinpoint the leak.
REMEMBER:Anincreaseintickindicates
youare approaching a leak, a decreasein
tick indicates you are moving away.
This instrument is not to be used as a
carbon monoxide investigative tool or
to quantify any gas concentration.
