Détecteur de gaz combustible

6-2 Automatic Ambient Reset Feature
This Combustible Gas Leak Detector features an
Automatic
Ambient Reset
function that sets the unit to ignore ambient
concentrations of combustible.
▪
Automatic Ambient Setup
- Upon initial power on, the unit
automatically sets itself to ignore the level of combustible
present at the tip. Only a level, or concentration, greater than
this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to ignore any
combustible present at turn on. In other words, with the unit off
if you place the tip up to a known leak and switch the unit on,
no leak will be indicated!
Ambient Reset Feature
- Resetting the unit during operation
performs a similar function; it programs the circuit to ignore the
level of combustible present at the tip. This allows the user to
"home-in" on the source of the leak (higher concentration).
Similarly, the unit can be moved to fresh air and reset for
maximum sensitivity. Resetting the unit with no combustible
present (fresh air) causes any level above zero to be detected.
