4 buying skills you don't know about multimeters
1. The multimeter's accuracy and display digits
Accuracy and display digits are the most fundamental and significant multimeter indicators. In general, the accuracy increases with the amount of digits the multimeter displays, and vice versa.
2. The multimeter's measurement technique and AC frequency response
The multimeter's measurement technique is mostly used to measure AC signals. Different frequency responses emerge as the frequency of the AC signal changes, having an impact on the multimeter's reading. Multimeters may measure AC signals using two different techniques: average value and real RMS measurement.
3. Use and range of measurements
Manufacturers of various multimeters will create various functional measurement ranges. Normal multimeters are able to test AC and DC voltage, current, resistance, on-off, etc., however some of them lack a current function to save money.
4. Evaluation of Protection and Stability
A decent multimeter has effective self-defense. For instance, certain multimeters will immediately sound a buzzer alarm if they are put into the incorrect test lead line. Don't just get the cheapest multimeter you can find; instead, choose one that is usable and useful.
