4. Watch for the yellow lamps to illuminate, and listen for a tone. When the
instrument detects a leak source, its yellow lamps will illuminate and it will emit
a different audible tone.
5. When the D-TEK CO2 signals a leak, pull the probe away from the leak for a
moment, then bring it back to pinpoint the location.
6. If the concentration of carbon dioxide is high, press the sensitivity switch once
to change the threshold level to the LOW sensitivity setting before repositioning
the probe at the suspected leak source. The LOW sensitivity setting helps find
the exact site when a leak is large.
7. Once you have isolated the leak source, return the sensitivity setting to HIGH
to continue using the D-TEK CO2.
8. When you’ve finished leak-testing, turn OFF the instrument.
Recharging the Power Stick
A fully charged power stick should provide power for greater than 6½ hours of
continuous operation. To recharge the power stick, use one of the instrument’s
power cords.
NOTE: The D-TEK CO2 does not need to be fully charged to operate.
Additionally, the power stick does not need to be fully discharged before
recharging.
