Chapter Three: Overview

Front Panel Controls

Zero Control

This control is used as a fine zero for the pressure transducer. The pressure transducer should be
pumped down below its resolution before this adjustment can be made. The zero control on the
pressure transducer is used as a coarse zero.

Note

To access the remaining front panel controls, you must remove the plastic
bezel and lens.
