7 Manual Zero Mode
Manual Zero mode operates similar to Pinpoint mode, but is identified by the MODE
indicator slowly flashing. Manual Zero mode allows the user to manually zero to the
background refrigerant by pressing the SENS/ZERO button. Once the new zero point is
set, D-TEK 3 will not alarm unless a higher concentration of refrigerant is detected.
Manual Zero mode beeps faster at the zero point than other modes. If the
concentration is lower than the current zero point, the beeping slows. This allows the
user to know if they are moving away from the leak by listening to a change in the beep
rate.
There is no sensitivity setting in Manual Zero mode.
Manual Zero mode requires an extra warm-up time of up to 15 minutes for optimal
performance.
8 Earbuds and Volume Control
A headphone jack is located on the right side of D-TEK 3 for listening to the alarm
sounds through headphones or earbuds.
If attempting to use headphones not supplied by INFICON, be sure to test
them carefully to avoid hearing damage.
A volume button is located next to the headphone jack. Press the volume button to
toggle from 100% volume, to 50% volume, and to mute. The volume defaults to 100%
at startup. When headphones or earbuds are plugged in, the volume toggles between
100% volume and mute.
