† Resolution uncertainty is error due to limited display digits. Actual

uncertainty can be calculated as

± (1 in least significant digit) / Reading

For a 3.5-digit display, worst case is at 300W. Least significant digit is

one watt, uncertainty is ± 1W out of 300 or 0.34%. For a 4.5-digit

display, least significant digit is 0.1W, so the uncertainty is 0.034%
