4) Now that you have the accuracy for the instrument, you can add it to the accuracy of the

uid. The uid is accurate to ± 1% of the stated value in KU. The viscosity standard is

calibrated at 104.8 KU, ± 1% is equal to ± 1.0 KU.

0.9 KU (instrument accuracy)

+ 1.0 KU (uid accuracy)

1.9 KU (total allowable error)

5) Total allowable error for the calibration check in this example is 104.8 KU, ± 1.9 KU

(102.9 KU to 106.7 KU). Since the measured reading of 105 KU falls within this range, the

Viscometer is considered in calibration.
