Anecdotal Notes in Alcohol Standard Log

Tip 29: Obtain disclosure, of the full #duisimulator alcohol standard log, to search for anecdotal notes of difficulties experienced by simulator change QTs.

An anecdotal note is a good clue in defence investigation of the possibility that the simulator jar was chipped at the edge or cracked. Does further disclosure of maintenance records reveal that the simulator jar needed to be replaced in the next few months? Did a prior solution change officer have difficulty getting a good seal between the jar and the housing and so over-tightened the jar? Was the jar eventually cracked? Was the alcohol standard at equilibrium at the time of your client's subject tests? If not, Henry's Law does not apply and the alcohol standard / approved instrument system was not reliable.
