Thermo Scientific 146iQ Instruction Manual 3-23
The Pressure Calibration Screen is used to calibrate the pressure sensors on
the Flow/Pressure DMC board to zero, span or factory default values. The
Pressure Calibration screen is only visible when there is an ozonator and/or
a photometer installed in the instrument.
Use the

3 Reading: Under the column labeled Reading, current
reading of each pressure sensor. Sensor 1 is connected to the pump
(vacuum) side of the photometer capillary, and in the 146iQ is the
sensor on the bottom of the board. Sensor 2 is a differential
pressure sensor that is connected to the 2 sides of the ozonator
capillary. Sensor 3 is connected to the bench (pressure) side of the
photometer capillary, and in the 146iQ is the sensor on the top of
the board. The Sensor readings are only valid if their corresponding
options are installed, and can otherwise be ignored.

Atmospheric Sensor 1

3: User should expose the sensor to
atmospheric pressure by disconnecting the tube attached to the
sensor. Under the column labeled Reading, the user enters the
current atmospheric pressure in mm Hg units. Under the column
