3.0 INTRODUCTION
3.1 GENERAL DESCRIPTION
The RH CALIBRATOR is a microprocessor based, programmable humidity control
and measurement instrument with many microprocessor controlled features built-in.
Using the NIST Traceable Optical Chilled Mirror primary measurement technique,
the RH CALIBRATOR was developed for precise calibration of RH Sensors and
Transmitters, as well as laboratory and research applications.
3.2 SYSTEM OVERVIEW
The RH CALIBRATOR has a Test Chamber, a menu driven LCD graphics display,
Automatic Balance Cycle (ABC), a selectable analog output, and an RS-232C serial
port.
