Page 8: Summary Of Features
DPM1B Operators Manual Summary of Features The Tester is a hand-held pressure measuring device, designed as an aid in the performance testing and troubleshooting of pneumatic or hydraulic systems. A liquid crystal display (LCD) reading indicates pressures manually generated from an internal chamber. -
Page 9: Testing Capabilities
Pneumatic Transducer Tester Specifications Tester using a Y-connector. Pressure is applied to the system as normal, usually with a squeeze bulb. The results can be compared between the Tester and the manometer under test. Testing Capabilities Verifying the proper operation of a blood pressure transducer can be a tedious and time-consuming task. -
