Fluke 707 Loop Calibrator User Manual
The Fluke 707 Loop Calibrator is a pocket‑sized instrument that supplies and measures loop currents (0‑20 mA or 4‑20 mA) and DC voltages up to 28 V. It offers Source, Simulate, Measure, and Loop Power modes, automatic ramp output, and a SpanCheck function for verifying transmitter zero and span.
The manual includes safety information (IEC 61010, CAT II 130 V), battery requirements (single 9 V alkaline), environmental limits, dimensions, weight, and warranty details. It also explains how to adjust the auto‑off timer, change current ranges, and interpret status symbols. This manual is written in Chinese.
