Detailed accuracy indicator

Accuracy is specified for a period of one year after calibration, at 23

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)
