Refrigeration Index Graph View

View Menu > Graph View > Refrigeration Index Graph View

Temprecord can also calculate and display RI (Refrigeration Index) statistics.  To enable this facility, click on Options/Statistics, and make sure Show Refrigeration Index Statistics is checked.  The RI statistics are calculated between the start and end samples only.  Remember that if a file has just been loaded the start sample is set to the first sample and the end sample to the last sample.

The RI value is calculated for each sample and is cumulative.  If the temperature falls below 7.0 degrees C the RI value at this point is reported.  The RI value is also reported at the end sample, regardless of whether the 7.0 degree C temperature was reached.

The time interval taken for the temperature to fall to 7.0 degrees C is also reported in the statistics view.

The RI value displayed is a logarithmic value, and represents the base 10 log of the number of generation increases over the time period.

The Y axis for the refrigeration index is shown on the right-hand edge of the graph view.  It is always scaled so that the trace occupies the whole graph.

You can change the colors of the refrigeration index graticule and trace in options.
