What to look for when choosing a digital multimeter?
A good multimeter should have a wide measurement range, increased test accuracy, speed, safety and convenience .
Studying the main parameters and features of equipment of this class will help you avoid mistakes when choosing:
- Type of measurements. All multimeters allow you to test electrical parameters such as current, DC/AC voltage, resistance. A number of models are equipped with a “continuity test” using an audio signal, a temperature meter, and an option for checking diodes and transistors. Advanced devices can determine frequency and capacitance.
- Test range. Device specifications always indicate threshold values for individual parameters. For home use, in most cases, a multimeter with a maximum voltage of 600 volts and a current of up to 10 amperes is suitable.
- Basic error. This parameter can be a starting point, but it does not always reflect reality. Different measurements have their own error, which can differ greatly from the base one. When choosing, you should decide for which parameters the device will be primarily used to measure.
- Control. Most inexpensive multimeters are equipped with manual switching of measurement ranges. The automatic system found in professional devices provides more accurate and safer testing.
- Performance. The number of samples per second determines the rate at which the information on the screen is updated. A standard value for most multitester models of 2 or 3 units is enough to obtain a reliable result.
- Memory mode. The HOLD button, found on some multimeters, allows you to freeze the readings on the display until reset. This is very convenient when working in difficult conditions. The ability to load and unload data into/from memory is found in professional devices.
- Power supply of the device. As a rule, multimeters are equipped with 9-volt Krona batteries or AA/AAA batteries. The system of automatic power off when stopping work allows you to significantly save the discharge of sources.
