The detection response time is less than the second. The operator must wait, for each point
to control, the time necessary for a possible detection.
•
For quick response and good detection, the sniffer probe should be as close as possible
to the leakage point to be controlled.
•
When a leak is detected, the light ramp lights in proportion to the value of the detected
leak.
o
Immediately
remove the probe from the leakage point to avoid
saturation
of the cell.
o
In case of big leaks, the degassing of the cell causes the lighting of the
ORANGE
light
" D "
.
Wait until the LED goes off " D " and possibly the light " S " before continuing
the detection.
Example :
With Sensitivity switch in position
"x1"
Estimation of the value of the leak
detected on the light beam :
- 1g/year light 1 on
-
5 g/year light 5 on
