Teledyne API T703/T703U Calibrator Operation Manual Principles of Operation range sensor. This data is used by the CPU when calculating the O concentration inside the absorption tube. This value is displayed on the front panel as a test measurement called PHOTO SPRESS. Note that this value is converted to units of Inches of Mercury (IN-HG-A) when displayed on the front panel.

Disk On Module (DOM) The DOM is a 44-pin IDE flash chip with a storage capacity up to 256 MB. It is used to store the computer’s operating system, the Teledyne API firmware, and most of the operational data. 9.2.2.2.
Page 186: Valve Control
Valve Control The relay board also hosts two valve driver IC's, each of which can drive up four valves. In the T703, the relay PCA controls only those valves associated with the generator and photometer. In the T703U, the relay PCA controls two additional valves: the Divert valve and the O Gen valve.
