Accuracy class & limit

The accuracy class of the pressure gauge and the limit deviation tolerance are decided as follows.
Accuracy classLimit deviation tolerance
Scale rangeAScale rangeB
Class 0.6±0.6±0.9
Class 1.0±1.0±1.5
Class 1.6±1.6±2.4
Class 2.5±2.5±3.8
Class 4.0±4.0±6.0

※The value of the limit deviation tolerance is shown by the percentage of pressure (all scale ranges).
