Optional Function

¤ HART Function:completely replace HART communicator;set or calibrate smart transmitter’s range; force the output current of intelligent transmitter at fix value(20mA, 12mA, 4mA ) set linear or square function; Set up linear or square functions, which can HART reset the pressure sensor of transmitter, etc.;

¤ Pressure module function: through RS232 communication port, it can be used together with our COMPANY's ET-CY series pressure module, for on-site verification of pressure transmitter, pressure switch, pressure gauge, blood pressure meter or other pressure instruments, and also for precise measurement of pressure;Support 12 pressure units: kPa, MPa, Pa, PSI, inHg, inH2O, mmHg, mmH2O, bar, Mbar, ATM, kg/cm2, etc.

¤ Temperature difference measurement function: the accuracy is up to 0.003℃. This product can measure the temperature difference between two points in the space, and complete a temperature difference data collection within 0.4 seconds, effectively improving the measurement accuracy.The 10-minute fluctuation during the test can be calculated in real time.Before using standard platinum resistance or standard thermocouple for measuring work, the measurement results can be traced through the input of certificate value, and meet the requirements of the thermostatic tank test specification for electrical measuring instruments.

¤ Standard temperature measurement function: Comparing with common thermocouple measurement and RTD measurement,the difference is that  this measurement method can trace the temperature by certificate value,the supported standard thremocouple and RTD are as followed: S、R、B、T,Pt25、Pt100 

¤ Arbitrary sensor’s measurement function; Users can transform the measured physical quantity(Pressure, flow speed, temperature,etc) to voltage, current, resistance,etc conveniently for measurement. Besides, Users only need to input the response curve in advance, and the multimeter will adopt the internal algorithm for numerical conversion and correction, and finally the measured physical quantity will be displayed on the screen.You are free to edit and modify the display units of the measured physical quantities.

¤ Precision temperature control function; Precision temperature control function will realize the temperature closed-loop control of thermostatic equipment, which replace the high precision PID controller.Under the condition of thermostatic equipment and network voltage,temperature fluctuation will be better than 0.02℃/10min (Thermostatic Bath)

Measurement function of ρ’s value: can measure duty ratio of periodic square wave signal; verify and calibrate the PID parameter of Various digital temperature indicating regulators which is outputted by time scale

¤ Thermal Conversion Function: realize the conversion between various electric quantity and temperature.The types of electric quantity and temperature conversion include: working thermocouple, industrial rtd and various temperature transmitter.

¤ Numerical setting mode:its with the most flexible and convenient way to set output value; User can use the numerical keyboard to set output value directly, and can realize the incremental setting by direction key.In addition, the equipment also has a step or ramp numerical setting mode that can be numbered.

¤ Sinusoidal output function: The verification/calibration of some process logger (especially mechanical logger); Usually It involves running test, and it can provide signals to the measured table by using sinusoidal output mode.

¤ Data Record Function:  with powerful record management function, it can establish up to 32 device numbers. Each device number has 16 record pages, and each record page contains four basic information: time, measured value, output value and custom value.Users can carry out equipment management, record deletion and other operations according to requirements.
