The DMT quick release toggle vent valve (yellow) is fixed to the pannel of the DMT Control Unit.

The valve is used to rapidly flush the pressure after the B-reading.

The handle must be in the horizontal  position when pressurising the DMT and lifted in the vertical position to flush all the gas rapidly after the B-reading.

When this valve is used to flush the gas, the C-reading may not be taken.


Important Note: The handle of this vent valve should normally be in the lifted position (flush) and lowered only during DMT readings.

If the handle is rotated for more than 1 complete turn, it may damage and start leaking.
