WhAT’S IN ThE CASE
The CGD900 comes fully assembled in a padded carrying case, along
with a leak test vial that enables you to check that the unit is performing
properly. See page 5 for instructions for performing this test titled
“Using the Leak Test Vial”.
SAFETY INSTRUCTIONS
WARNING: Never use a flame to illuminate an area where combustible
gases could be present.
OPERATING INSTRUCTIONS
All of the CDG900’s controls and indicators are on the unit’s front panel.
Familiarize yourself with the nomenclature in the picture below before
turning on and operating the unit.
Before the CGD900 can be put to use, it must execute a three-step
startup sequence:
1. TURN ON. Press the on/off button once to turn on the unit, and
again to turn it off.
2. WARM UP. Once the unit has been
turned on, it automatically begins heating the
sensor. During warm up, the digital leak size
indicator flashes “0”, the sensitivity level indi-
cators illuminate in sequence, and the unit
beeps slowly and repeatedly. The warm up
cycle normally takes less than 10 seconds.
3. READY. The CGD900 is ready to begin
searching for leaks when the display stops
flashing “0”, the green LED for NORM lights up,
and the audio “beep” increases in frequency. To
silence the beep, push the Mute button again.
(Note: It takes a few seconds to restore the
sound if the Mute button is pushed quickly and
repeatedly.
