Guys,
It seems that the gaps between currents specified for various classes
of PDs during the classification procedure are too small and may produce
a measurement accuracy issue.
I am suggesting to change Table 3 in the Draft for the following numbers:
Class0 <1.5mA
Class1 8 - 10 ma
Class2 13 - 16 ma
Class3 19 - 23 ma
Class4 27 - 33 ma
Class5 37 - 45 ma
Greater than 49mA: Invalid result, not a PD.
Comments?
Yair.
