10 About Calibration
6. Compare the value displayed for the average volume to the value recorded on the calibration
standards case. These two values should agree plus or minus the tolerance obtained using
the following calculation:
Tolerance = (chamber volume * 0.0003) + (Value recorded on Standards case * 0.0003)
Example: calculate the tolerance for a 10 cm

pycnometer with a value of 6.372242cm

recorded on the case as :
Tolerance = (10 * 0.0003) + (6.372242 * 0.0003) = 0.003 + 0.0019116726 = 0.005cm

If the values do not agree, a leak may be indicated. Check the system for leaks. Then repeat
steps 1 through 6. If the values continue to disagree, contact your Micromeritics Service
Representative. See Diagnostics using the Software on page9 - 1.
7. Remove the standards and place them back into the case.
