This video demonstrates how to perform a pressure switch calibration with the Fluke 729 Automatic Pressure Calibrator.

How to calibrate a pressure switch with the Fluke 729:

1. Vent the 729 and zero out the pressure for a clean test
2. Press the TASKS button and select Pressure Switch
3. Configure the test
4. Press continue once configuration is complete
5. Press F4 to begin the Auto Test

The Fluke 729 Automatic Pressure Calibrator has been designed specifically with process technicians in mind to simplify the pres­sure calibration process and provide faster, more accurate test results. Technicians know that calibrating pressure can be a time-consuming task, but the 729 makes it easier than ever with an internal electric pump that provides automatic pressure generation and regulation in an in an easy-to-use, rugged, portable package.

The ideal portable pressure calibrator, the 729 allows you to simply type in a target pressure, and the calibrator will automatically pump to the desired set-point. Then, internal fine adjustment con­trol automatically stabilizes the pressure at the requested value.

The Fluke 729 can also automatically test multiple pressure test points and automatically document the results. Calibration is as easy as typing in the starting and ending pressure and the number of test points and tolerance level. The 729 does the rest.

Built-in HART communication capabilities enable HART transmitter mA adjustments, light HART configuration and the ability to adjust to applied 0% and 100% values.

Some key features include:

• Automatic pressure generation and regulation to 300 psi
• Easily document the process using onboard test templates
• Automatic internal fine-pressure adjustment
• Measure, source and simulate 4 to 20 mA signals
• 24V loop power for powering transmitters for tests
• Built-in leak testing for verifying test setups for leakage
• HART communication for testing HART smart transmitters
