Test Units:
15CHHC2010 CNA02130778, Code:2009-08-03
15CLE CNA1310KH3/02290, Code:2011-04-15
External 3V power supply, CR2032 Cells.
Fluke 8060 Multimeter
------------------------------------------
I have verified that both the HP15CLE and the HP15C2010HHC draw about 20mA when any key is pressed. I tested this with both an external power supply and an externally applied CR2032 cell. They both draw about 20mA when a program (the LBL A + GTO A loop) is running.
Also, when the ON key is pressed to turn the calc off and held, it continues to draw 20mA until released.
Program execution time Performance:
The 15CLE is about 20% faster than the 15C2010HHC unit (also running the LBL A + GTO A loop). I wonder if this is due to code differences or manufacturing/component tolerances.
