1. General Information
This manual contains technical and general information relating to the installation, operation, and calibration of the Hastings 760 Plus vacuum gauge which is comprised of a piezo vacuum transducer (760s) and power supply/display.
The 760s piezoresistive type transducer has one side of its diaphragm evacuated to a low reference pressure then sealed to produce an absolute pressure signal output. This output signal is linear- proportional to the applied pressure and is independent of gas composition.
The power supply/display provides 24 VDC excitation power for the 760s transducer and a four digit dual setpoint meter relay for monitoring, measurement and control applications.
For best performance, this instrument should be operated with the appropriate Hastings accessory items. Attempting to use a Hastings product with other manufacturers equipment may result in damage to all equipment.
