The XFQ-4000 handheld intelligent signal generation calibrator is an intelligent industrial instrument calibrator with high accuracy and small size. It can be used for on-site calibration of industrial instruments and laboratory instrument calibration. The XFQ-4000 has powerful functions and can simulate and output various signals required for industrial control process measurement and control, such as millivolt level and volt level voltages, milliampere level currents, and hertz level and kilohertz level frequencies. It can also measure the signals generated in these industrial control processes.
