Weighing 10 mg, 50 mg, 100 mg; 1 gm and 200 gm. Record the result in Daily
verification log book.
5.2.6.
Calibration of measurement of uncertainty and drift of the Analytical Balance:
5.2.7.
Place 200mg standard calibrated weight on the pan.
5.2.8.
Record the display of the weight.
5.2.9.
Remove the weight & again place the weight on the pan & record the display once
again.
5.2.10.
Repeat the above operation to get ten readings Calculate the standard deviation of ten
readings.
5.2.11.
The measurement uncertainty shall be considered satisfactory if three times of standard
deviation of not less than 10 replicate weighing divided by amount weight does not
exceed 0.001. Record the observations in the calibration record.
5.2.12.
Now place 5.0 gm weight on the five different places as shown below to find the drift
and record the observation.
