Extech DM110 Information
The Extech DM110 is a pocket-sized digital multimeter that offers a wide range of features for electrical troubleshooting and basic electronics work. It features autoranging, which means that the meter automatically selects the correct range for the measurement being made. This makes it easy to use, even for beginners.
The DM110 also has a number of other features that make it a versatile tool, including:
- A large, backlit LCD display for easy viewing in low-light conditions
- A relative mode, which allows you to measure the difference between two voltages or resistances
- A data hold function, which freezes the display so you can make accurate measurements
- A diode test function, which allows you to check the polarity and continuity of diodes
- A continuity beeper, which emits a sound when the meter detects a low-resistance connection
The DM110 is powered by a single CR2032 battery, which is included. It comes with a carrying case, test leads, and a user manual.
