Error in Egg Testing Haugh Unit Calculation

It has come to our attention that the Haugh Unit calculation in Exponent/Exponent Lite software (versions and lower) has an error in the location of a bracket within the formula. This is due to how formulas are translated into computer instructions.

Incorrect: HU = 100log(h – (1.7w)0.37 + 7.6)

Correct: HU = 100log(h – 1.7w0.37 + 7.6)

We have made the appropriate correction for all future software versions (including Connect software) and can advise the following:
The grading of eggs may be affected. Changes will be most noticeable for those eggs that have a thin albumen (below 4mm) and coupled with a higher weight (e.g. 75g). For the majority of egg weights and albumen heights (that would have resulted in a high Haugh Unit) the egg grading will be unchanged.

Dough Inflation System flow rate calculation

An error was found in Exponent versions prior to with the flow rate calculation of the Dough Inflation System Type 2 model. The adjustment for the larger piston diameter was not being made so the actual flow rate was higher than displayed in the T.A. Settings window.

For operators of the DR/DIS2 who have created their own projects or made copies of the sample projects, the Dough Inflation System will continue to operate in the same way as before i.e. the displayed value of 26.7 will continue to operate at the actual flow rate of 60.9 cm3/sec for compatibility with existing results.

The new sample projects and library sequences (supplied from version onwards) correct this issue and run at the displayed flow rate i.e. 26.7 cm3/sec. Operators who have been directly using sample projects from previous Exponent versions, and wish to continue using the same flow rate as the previous versions, will need to change the flow rate value to 60.9 cm3/sec.
