- F or a standard Si diode applied in conduction direction the conduction volt-
age between 0.400 V to 0.900 V is displayed. The display "000" indicates a
short circuit in the diode, display values "OL" indicate an interruption in the
diode.
- F or a diode applied in reverse direction "OL" is displayed. If the diode is
defective, "000" or other values are shown.
