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^oF. The actual temperature is somewhere between 98.50^oF and 101.50^oF.

Or if the thermometer reads 50.00^oF then the actual temperature is between 49.25^oFand 50.75^oF.

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