multi functional process verification instrument

? Product function ? 1, divided into the upper and lower display screens. The upper part of the screen is used to display voltage, current (loop powered), millivolts, resistance and on-off tests of the isolation module. The lower part of the screen can display the measured and output voltage, current, frequency, ohms, and thermal resistance (RTD) and thermocouple (TC) in the form of temperature. 2, due to the use of isolated loop power supply, only one DY-RX can complete the calibration of a variety of two-wire transmitters. 3, thermocouple (TC) measurement provides cold end compensation. 4, customize the output range, to facilitate the call of different application values. 5, manual step, automatic step, step and slope output.
