HS211 Process Signal Calibrator integrates measurement and output
of voltage, current, resistance, frequency, thermocouple, thermal
resistance and pressure measurement into one .It can connect external
digital 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.

Features
◆ Intelligent operation form and instructed by graphic buttons.
◆ It supports pressure, temperature unit switch and the mutual
    calculation for voltage,current and temperature values and conform to
    ITS90 International temperature standard .
◆ 30V voltage can be beared with any two jacks by misoperation.
◆ The current terminal can be beared 1A current by misoperation for long
    time .Once the misoperation cancelled, the items will return to the normal
    state.
◆ With automatic cold junction compensation, built-in cold-junction
    heating module, it quickly tracks the temperature changes, and carry out
    cold junction sensor calibration.

Working environment
◆ Using environment temperature:(-5~45)'C
◆ Relative humidity:20% - 90% No condensation
◆ Store environment temperature:(-20~55)'C
◆ Atmospheric pressure :(86~106)kPa
◆ Power supply:rechargeable battery or power adapter

Function
◆ Simultaneously measure and output.
    Measuring voltage, current, resistance, frequency, thermocouple,
    thermal resistance.
◆ Output voltage, current, resistance, frequency, analog thermocouple,
    analog thermal resistance.
◆ Support thermocouple type S,R,B,K,N,E,J,T.
◆ Support thermal resistance type Pt10, Pt100,Cu50, Cu100.
◆ Calibration temperature second instrument (temperature transmitter,
    temperature switch and so on). Analog temperature transmitter function.
◆ Calibrating Hart function pressure transmitter directly.
◆ Accomplishing pressure calibrator together with digital pressure module
