After the hardware is configured and tested, the Model 225 searches through the
stored results to locate the last chocolate sample test result. Test results are
stored in a memory device which retains the results even while power is off.
Searching Stored Results
The results are searched starting from the beginning of memory looking for the
last valid result. Corrupted or non-used result memory is ignored. A progress
bar is shown across the bottom row of the display indicating continuing
scanning. During this scan time, the heater and cooler control circuits are
working to obtain the desired temperature
The LCD will show the current and desired temperature for both the cooler and
heater.
Cooler * WAIT * Heater

Once the cooler well and heated probe tip are at the desired temperature, the
LCD will show the message below. The Model 225 is now ready to test
chocolate.
