Manual Zero Mode - Inficon D-TEK 3 Guia De Inicio Rapido

Quick Start Guide
Turning D-TEK 3 on and preparing for use
1
Long-press the power button to turn D-TEK 3 on or off.
ð If the power indicator does not illuminate, the battery is very low and needs to be
charged. D-TEK 3 can be used while charging.
2 D-TEK 3 begins a warm-up for 45–90 seconds. When the warm-up is complete,
D-TEK 3 is ready for use.
3 To switch modes, press the MODE button. This toggles between Pinpoint and
Manual Zero modes.
ð D-TEK 3 always starts up in the last mode that was used.
Using 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 (2.5 to 5 cm [1 to 2 in.] per second) move the probe past each possible leak
point. If a leak is detected, D-TEK 3 alarms and the leak indicators illuminate.
ð In Pinpoint mode, D-TEK 3 automatically zeros to the background refrigerant
concentration after a few seconds. When this occurs, either continue looking for
a higher concentration of refrigerant or move to an area of lower concentration
to reset the zero point.
3
When a leak is identified, pull the probe away from the leak for a few seconds and
then return the probe to the suspected leak site to verify the leak.
ð For leaks of varying sizes or SAE applications, press the SENS/ZERO button to
switch the sensitivity mode. The current sensitivity is indicated by the sensitivity
(SENS) indicators. Refer to the full operating manual online for more information
about SAE applications.

Manual Zero mode

Manual Zero mode operates in a similar way to Pinpoint mode, but allows the user to manually
zero the instrument to the background refrigerant by pressing the SENS/ZERO button. The
SENS indicators flash briefly to indicate a new zero point has been set. The MODE indicator
flashes slowly while in Manual Zero mode.
