Volt
Ohms
function is useful for accurate resistance measurements
in a circuit, which includes semiconductor devices. There is
no
need
to
remove the resistor or semiconductor device from the circuit.

nS
(Conductance)
1)
Rotate the function selector switches to the capacitance/nS position.
Press the
ALT-F
key once to select the
nS
(conductance) function.
2)
The secondary digit display reads the resistance value of the measure-
me
nt
in
Gigaohms, while
the
primary display reads the conductance
value in nanosiemans which
is
calculated from the
equation,S
=
tJR.
This measurement function is
very
useful
f~r
checking extremely
high
resistances
or
leakage properties of insulation materials etc.

ZENER
DIODE
1)
Rotate
the
function selector
switch
to
the
Ze
ner
diode/femp
position.
The Zener annunciator
will
appear
on
the lower left of the display.
2)
With the test leads
open
the primary display
will
read about
2OY,
this is
the maximum
open
circuit test voltage. The secondaty display will read
lmA,
the constant t.est current.
The Zener diode function
is
very
useful for analyzing complex circuits
that include semiconductor devices such as
les,
transistor, Zener etc.
The
Zener
diode function has a test voltage
much
higher than the test
voltage
in
the diode
test
~
which is commonly seen,
in
most digital mul-
timeters. This function along
with
Lo
Volt
Ohms
function makes this
instr
ument
a powerful tool for various electronic circuit analyses.
