7 Pinpoint Mode
1. Place the tip of D-TEK 3 as close as possible to the suspected leak (do not
block the air flow).
2.
Slowly move the probe past each possible leak point.
ð
If a leak is detected, D-TEK 3 alarms and the leak indicators illuminate.
3.
When a leak is identified, pull the probe away from the leak for a few seconds
and then recheck the spot to verify the leak.
In Pinpoint mode, D-TEK 3 automatically zeros to the background refrigerant
concentration and only alarms again with a higher concentration of refrigerant. When
this occurs, either continue looking for a higher concentration of refrigerant or move
the probe to an area of lower concentration for a few seconds to reset the zero point.
Press the SENS/ZERO button to switch the sensitivity setting. When working with a
large leak, it can be easier to pinpoint the leak location using a lower sensitivity
setting. The current sensitivity is displayed by the sensitivity (SENS) indicator.
