1.Blue screen display, can be used all-weather. 2.Has a ferquency(Hz) measurement and emulation function.
JC-ZJF-3 process signal simulation calibration instrument is specially design for industry process control, intelligence menu prompt, digitization operation, kompleta function, 18 input, output of thermal measurement, synchronous operation, independent operation, and isolate from each other. Possess this instrument, you can easy to complete the routine maintenance and calibration.
Characteristic
Blue screen display, can be used all-weather.With the signal output and measurement of V, mV, mA, Ω and thermocouple (TC), resistance temperature (RTD).Has a ferquency(Hz) measurement and emulation function.24V DC power distribution provide the loop power for transmitter, and can measure the output value of mA form transmitter in a same time.Measure the thermocouple (resistance temperature), display rhe mV(Ω), degree celsius in a same time, not need to check the reference table any more.Using the high-precision temperature sensor to provide for cold junction compensation for thermocouple.All the signals can trimming or continuous add or subtract in arbitrary decimals.Has the function of simulation transmitter, can calibration DCS channel 4-20 mA loop current.Has RS232 comminication interface, can realize the fast revise of instrument out-of-tolerance though the PC.Output index
