Access user manuals, safety guides, and operating instructions for various generic, unbranded, and model-specific digital multimeters.
This page serves as a repository for user manuals and documentation for generally branded or white-label ดิจิตอลมัลติมิเตอร์. A digital multimeter (DMM) is an indispensable tool for measuring electrical values such as voltage (โวลต์) ปัจจุบัน (amps), and resistance (ohms).
While many multimeters are produced by major manufacturers, numerous affordable and versatile models—such as the KJ103 or FY106B—are distributed under generic names or minor brands. Each manual provided here offers critical information on device operation, safety ratings (CAT II, III, IV), correct dial settings, and maintenance procedures including battery and fuse replacement.

Most digital multimeters can measure AC/DC voltage, AC/DC current, and resistance. Advanced models may also include functions for capacitance, frequency, temperature, diode testing, and non-contact voltage detection (NCV).
If your multimeter does not have a prominent brand name, look for the model number printed on the front or back of the casing (e.g., KJ103, DT-830B). You can search this archive using that model number.
Multimeters are rated for specific voltage categories (CAT ratings). Using a meter outside its rated capacity can be dangerous. The manual outlines the maximum limits and necessary safety precautions to prevent injury or device damage.
