Preparing for Use
If the unit does not turn on, the battery is low and needs to be charged. D-TEK 3 can
be used while charging.
1
Long press the power button (located on the left side of the body of the
instrument) to turn D-TEK 3 On or Off.
ð D-TEK 3 begins a variable-time warm-up for 45 to 90 seconds. When warm-
up is complete, D-TEK 3 is ready to use.
2
To switch modes, press the MODE button. This toggles between Pinpoint and
Manual Zero modes.
D-TEK 3 always starts in the last mode that was used.
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.
