2.0 INTRODUCTION
DOCUMENTING PROCESS CALIBRATOR:
The Setra MicroCal is a pressure generating, modular pressure documenting calibrator.
The calibrator has been designed and optimized to meet the needs of our customers for
a capable system for the calibration, troubleshooting and documentation of very low
pressure measuring information.
The design of the MicroCal exploits years of experience in the calibration of Setra trans-
ducers, as well as NASA patented and Setra exclusive licensed technology.
Major Features:
• 7” Touchscreen Display, capable of storing thousands of Units Under
Test (UUT) data files.
• Portable, battery powered system, capable of full operation throughout
a typical work day.
• Closed loop pressure control which is immune to the effects of ambient
pressure perturbations, (doors closing, people moving around).
• Very low internal reference pressure standards, which are selectable to
match customer needs.
• Auto zero pressure “tare” function.
• Ability to source power to the UUT, or use external power supply.
• High resolution pressure control capable of precise generation and
pressure control in the micro inch of water column pressure ranges.
• Leak testing
• High accuracy MCPM modular pressure references give flexibility and
accuracy to the end customer.
• Modular battery to ensure all your calibrations are able to be completed.
