INTRODUCTION
Thank you for choosing a Pressure Calibrator from Crystal Engineering Corporation.
The 30 Series are compact and rugged pressure calibrators designed to bring laboratory accuracy to outdoor eld conditions. Every 30 Series Calibrator is
fully temperature compensated through extensive testing of all measured parameters while being exposed to environments of 0°C (32°F) to 50°C (122°F).
All 30 Series calibrators are intended for gauge pressure measurement. That is, they indicate the dierence between applied pressure and ambient baromet-
ric pressure. The zero button also can be used as a tare function - extending the functionality of the calibrator for special applications.
They w
eigh less than a pound and advanced technology is employed throughout the product line. Sensors are constructed with stainless steel isolation
diaphragms and permanent oil ll. This means 30 Series products can be used with gases and liquids.
Long battery life is achieved with a low power, RISC (reduced instruction set) type micro-controller for computation of complex algorithms. A 24 bit analog to
digital converter provides internal resolution of 1 part in 16.7 million. Internal resolution always exceeds the displayed resolutions for all measurements. Full
accuracy is maintained even while the low battery icon is ashing.
The 30 Series is specied in percent of reading - instead of percent of scale. Why? Because one 30 Series calibrator could replace several conventional calibra-
tors by covering a wide range of pressure with high accuracy.

odel 30 does not require any manual adjustments or trimming. All calibration is accomplished via an optically isolated communications port using a
USB physical interface. The optical isolation protects the Model 30 from electrical transients that may appear on the USB connector or cabling to a PC.
Your 30 Series can be customized through the use of our free CongM30™ software. Your personal computer can disable, enable, or modify a variety of
features of your 30 Series.
•
