During a labexercise we measured a value to be 26.3 mT. The teslameter was said to have an accuracy at +- 0.05%. This means we measured 26.3 +- 0.0132mT. However we are supposed to write a measured value with it's error in the last digit. But the error is smaller than the smallest digit we got from the measurement. Does this mean I shold not write 26.3 +- 0.0132mT and just write 26.3 mT without any estimation of the error?
