This manual introduces the use of the 725Ex Multifunction Process Calibrator. The instrument can be used to calibrate various process variables, including pressure, flow, temperature, voltage, current, frequency and humidity. This manual also introduces the safe use of the instrument.
This manual introduces the Fluke 725Ex multifunction process calibrator, covering safety notices, hazardous‑area restrictions, and basic handling procedures. It explains the device’s input and output terminals, button functions, display layout, and how to start, shut down, and adjust contrast.
Detailed sections describe measurement and source modes for voltage, current, resistance, temperature (thermocouples and RTDs), pressure, and frequency. The specifications chapter lists electrical ranges, resolution, accuracy, temperature coefficients, and battery requirements, while the service section outlines calibration, maintenance, and part replacement. This manual is written in Chinese.
