ACCURACY

• Accuracy is specified as % of reading + digit and is valid at 25C 3C, 55% RH 10%.

• Accuracy is valid from 10% of the range to 95% of the range

• Temp. Coefficient = + (0.2% of the range) per degree centigrade referred to 25C.

• Accuracy is not valid if display shows LO BAT. In this case immediately replace the batteries.

• It is recommended that calibration equipment used to verify the accuracy of the instrument should be 10 times more accurate.

• It is recommended to recalibrate the instrument once in year.
