It's the deviation for with the actual value lies.

#### Explanation:

Say you have a thermometer with and accuracy of +/-1.5%.

You take the thermometer outside and it reads the temperature to be ${100.00}^{o} F$. The actual temperature is somewhere between ${98.50}^{o} F$ and ${101.50}^{o} F$.

Or if the thermometer reads ${50.00}^{o} F$ then the actual temperature is between ${49.25}^{o} F$and ${50.75}^{o} F$.

As you can see, each of them have a range of value given -1.5% to value given +1.5%..
