ranges except 2
kQ
range
is
less
than 3.5V.
Diode Test 2 kQ.
200 kQ,
and 20
MQ
ranges supply
enough
voltage to
turn
on junctions
allowsing
a
"Diode Test".
The
2
kQ
range
is
the preferred
range
and
is
marked
with a
diode
symbol
(>*).
200Q, 20 kQ,
and 2000
kQ
ranges can
make
in-circuit
measurements
without turning
on
silicon
junctions.
