8 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.
