Uni-T UT58B Pros/Cons and My Thought
The Uni-T UT58B is a multimeter that is designed for general electrics and electronics work. It has a large display, a wide range of measurement functions, and a number of safety features.
Pros
- Large display: The UT58B has a large, backlit display that makes it easy to read even in low-light conditions.
- Wide range of measurement functions: The UT58B can measure AC and DC voltage, current, resistance, capacitance, frequency, duty cycle, and temperature.
- Safety features: The UT58B has a number of safety features, including an input protection circuit, an auto power-off function, and a CAT III 1000V safety rating.
Cons
- Manual ranging: The UT58B is a manual ranging multimeter, which means that you have to select the correct measurement range for each measurement. This can be time-consuming and can lead to errors if you select the wrong range.
- Input protection: The UT58B's input protection circuit is not as robust as some other multimeters. This means that it is more likely to be damaged if you accidentally measure a high voltage or current.
