HS212 Process Signal Calibrator intergrates measurement and output of voltage, current, resistance, frequency, thermocouple, RTD, pressure measurement into one .It can connect external pressure module and calibrate hart instrument. That is high precision, easy operation with english graphic touch buttons. It is widely used in power,oil , chemical, metallurgy ,metering etc. Feature 1.Intelligent operation form and instructed by graphic buttons. 2.It supports pressure, temperature unit switch and the mutual calculation for voltage , current and temperature values and conform to ITS90 International temperature standard . 3. 30V voltage can be beared with any two jacks by mistaking operation. 4.The current terminal can be beared 1A current by mistaking operation for long time .Once the mistake operation cancelled, the items will return to the normal state. 5.With automatic cold junction compensation, built-in cold-junction heating module, it quickly tracks the temperature changes, and carry out cold junction sensor calibration. Functions 1.Measuring and output voltage current,frequency,thermal resistance, thermocouple, RTD. 2.Simultaneously Measuring and output. 3.S、R、B、K、N、E、J、T thermocouple. 4.Measuring and output Pt10,Pt100,Cu50,Cu100 RTD. 5.Calibrating Hart instrument directly. 6.Connecting digital pressure module
