Indicator for Melt Pressure & Load Cell transducers -2

Keyboard lock/unlock : to prevent unauthorized operator actions The 350 ΢Ħ Outputs lock/unlock strain gauge bridge of the Melt pres-sure or load cell trasducer can be energized by an internal stabilized 5 or 10Vdc. The reliability of the strain gauge is continuously monitored.A simple front panel calibration routine is pro-vided to automatically remove zero and span offsets. The automatic calibration routine can also be activated by using one of the three standard digital inputs, as well as being activat- ed over serial communications. Tare function for load cells application is also provided.Also...
