Theory Of Operation; Introduction - Fluke RUSKA 7750i User Manual

Introduction

The ADTS's power supply, electronics, pneumatics, and sensor combine to form a
complete, stand–alone, measure and control instrument. This Chapter of the manual
describes the ADTS's component modules (Figure 2-1) and provides a general discussion
of each. The RUSKA 7750i has two pneumatic control and two primary transducer
modules.
