MO
range; 2 seconds maximum on
all
other ranges
These three ranges have enough
voltage
to
turn on silicon
junctions
to check for proper forward-to-back resistance. The 2
kQ
range is
preferred and is marked with a larger diode symbol on the front
panel
of
the instrument.
Thethree
non-diode test ranges will
not
turn
on silicon junctions so in-circuit resistance measurements can be
made with these three ranges
