3) When measuring voltage drop of PN, for a good silicon semiconductor
structure, normal positive reading should stay between 0.5V~0.8V.
Negative display being “OL” means open circuit; at this time, the red
test lead is positive pole, and the black one is negative pole. In addition,
“V” acts as unit of this range.
