labelled Ambient products on the Excel Temp Comp spreadsheet's Compensation
Template page shown below.
Only use the top 10 rows and do not extend into the next set of data rows. The
QMR Parameter tab Calibration Offset and Temp Offset fields will now show the
resultant corrected values.
8.10.4.3 Establishing Temperature factor
Testing should now be switched to normal products coming from the production
line at normal temperature other than ambient. If these are not available then it is
possible to take one of the leak tight components and replicate the temperature
conditions (i.e. cool or heat the component as required).
The selected part should be tested a number of times as the part reaches a stable
ambient condition providing there is a suitable relaxation period between tests.
The results of tests should show both the ambient and pressure results
progressively converging towards a stable result.
