ted 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%
