More info

The SUNWA DIGITAL MULTI TESTER (Model DT-832D) is a very common, entry-level, pocket-sized 3 1/2-digit digital multimeter that belongs to the widely replicated DT830 series. It is a manually ranging meter, typically manufactured in China, and is popular among hobbyists and for basic electrical troubleshooting due to its low cost and standard functions.

The "D" in the model number often indicates the inclusion of the Transistor hFE test function and sometimes Temperature (depending on the specific manufacturer).

Here is a description of its key features and typical specifications:

Key Features

Digital Display: Features a 3 1/2-digit LCD with a maximum reading of $mathbf{1999}$ (2000 count).
Buzzer/Continuity Check: Includes a built-in audible continuity buzzer that sounds when resistance is below a certain threshold (typically $approx 50Omega$ ).
Transistor Test (hFE): Includes a socket on the face of the meter for testing the DC current gain ( $text{hFE}$ ) of NPN and PNP transistors.
Diode Test: Measures the approximate forward voltage drop of a diode.
Square Wave Output: Some versions include a test function for generating a small square wave signal (typically $50text{Hz}$ ).
Overload Protection: Includes fuse protection for the $text{V}/Omega/text{mA}$ jack, but the $10text{A}$ range is typically unfused (and often restricted to intermittent use).
Low Cost & Compact: It is designed to be very affordable, lightweight, and pocket-sized.
