Lower would be more accurate.nothing909 said:
I don't know what the +2 means, either. Where did you see this? Can you post a link or a picture?nothing909 said:
Yea, I notice that now, that's why I was so confused. I couldn't find a clear explanation online so I came here. Thanks for clearing it up.Mark44 said:
The numbers ±1%+2 and ±2.5%+2 refer to the accuracy of a multimeter. The ± symbol indicates the tolerance or margin of error, while the numbers after it represent the percentage of error and the additional fixed error. So, ±1%+2 means the multimeter has a tolerance of 1% of the reading plus an additional fixed error of 2 units.
In terms of accuracy, ±1%+2 is more accurate than ±2.5%+2. This is because the former has a smaller tolerance of 1% compared to the latter's tolerance of 2.5%. This means that the readings obtained from a multimeter with ±1%+2 are closer to the actual value than those from a multimeter with ±2.5%+2.
Yes, the accuracy of a multimeter can affect your measurements. If a multimeter has a lower accuracy, it means that the readings obtained are more likely to have a higher margin of error. This can lead to inaccurate measurements, especially when working with sensitive or precise instruments.
The accuracy of a multimeter is usually indicated in the product specifications or on the packaging. Look for the ± symbol followed by a percentage and a fixed error value. The lower the percentage and fixed error, the more accurate the multimeter is.
It depends on your specific needs and the type of measurements you will be making. If you work with sensitive or precise instruments, it may be worth investing in a more accurate multimeter to ensure accurate readings. However, for general use, a multimeter with ±2.5%+2 accuracy may be sufficient.
