Amprobe 34XR-A Digital Multimeter User Manual

About this manual

The manual begins with safety information, noting that the 34XR‑A is UL, cUL and EN61010‑1 certified and rated for CAT 600 V and CAT II 1000 V use. It outlines proper handling, test‑lead voltage limits, and precautions for explosive environments.

It then describes the instrument’s functions—DC/AC voltage, current, resistance, frequency, duty‑cycle, temperature, capacitance, diode, and continuity testing—along with features such as true‑RMS measurement, min/max recording, hold, backlight, and automatic power‑off. Detailed step‑by‑step measurement procedures, range selection, overload handling, and maintenance tasks like battery and fuse replacement are included. This manual is written in Chinese.
