1.0 SAFETY INSTRUCTIONS
Use the calibrator only as specied in the manual, otherwise the protection provided
may be impaired.
Do not operate the calibrator in explosive gas, vapor or dust environments.
The calibrator is designed to operate from 14.4VDC removable Lithium Ion battery
source or from the AC adaptor that is included. Do not use AC adapters, chargers or
batteries other than those supplied by Setra.
If supplying external excitation to the Unit UnderTest in a measure mode, do not exceed
30VDC.
There are no user serviceable parts internally, removing the internal cover will void
warranty. Return the unit to the factory for re-certication or repair.
BEST PRACTICES FOR CALIBRATOR OPERATION:
Use the shortest length of tubing from the calibrator to the Unit UnderTest, during
pressure testing avoid vibration of the tubing.
Avoid movement of the calibrator during operation, avoid locating in a high vibration
environment.
Keep reference door closed when not changing modules.
Allow the calibrator to warm-up for 30 minutes before use. The calibrator can be turned
on during transport.

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 les.
• Portable, battery powered system, capable of full operation throughout
a typical work day.
• Closed loop pressure control which is immune to the eects 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 exibility and
accuracy to the end customer.
• Modular battery to ensure all your calibrations are able to be completed.
