Detailed accuracy indicator
Accuracy is specified for a period of one year after calibration, at 23
±
5
º
C, with relative humidity to 75 %.
Accuracy specifications are given as:
±
( [ % of reading ] + [ number of least significant digits ] ) (note:
“
number of
least significant digits
”
means the digits increased or decreased in least significant digits)
