However, if you are on a budget, then the Amprobe RS-3-PRO is a great option.
Here are some additional things to consider when choosing a multimeter:
- Accuracy: The accuracy of a multimeter is measured in percentage. A higher accuracy means that the multimeter will give you more accurate readings.
- Range: The range of a multimeter is the maximum value that it can measure. A wider range means that you can measure a wider variety of electrical values.
- Duty cycle: The duty cycle is the percentage of time that a multimeter can be used to measure current without overheating. A higher duty cycle means that the multimeter can be used for longer periods of time without overheating.
- CAT rating: The CAT rating of a multimeter indicates its level of protection against electrical hazards. A higher CAT rating means that the multimeter is better protected against electrical hazards.
- Weight: The weight of a multimeter is important if you will be carrying it with you. A lighter multimeter is easier to carry.
- Warranty: The warranty of a multimeter is important if something goes wrong with it. A longer warranty gives you more peace of mind.
