This manual introduces the Fluke 789 ProcessMeter, a battery‑operated handheld tester that measures electrical parameters and can output a stable or linearly varying current, as well as a loop power source over 24 V. It includes safety warnings, warranty information, and contact details for service and parts.
The guide covers basic operation (getting started, familiarizing with the meter, measuring voltage, resistance, diode testing, and using the current‑output functions), advanced features (auto‑hold, compensation test lead resistance, simulated mode, stable milliamp output), maintenance (battery replacement, fuse replacement, calibration), troubleshooting, and full technical specifications. This manual is written in Chinese.
