Radio Shack 2200087 - Advanced Operation: Comparative and Temperature Measurements; Using a Baseline Reference; Measuring Temperature

Using
a
Baseline
Reference
Abaseline
reference
allows
you
to
compare
components
directly.
For
example,
you
can
compare
resistors
in
a
set
by
measuring
one
resistor
as
the
baseline
and
then
measuring
how
closely
the
remaining
resistors
match
the
baseline.
1.
Select
the
function
(not
°C/°F,
dBm,
9),
DF,
LOGIC,
or
hg).
2.
Press
RANGE
to
select
a
range
3.
Connect
the
test
leads
to
the
component
whose
measurement
you
want to
use as
a
baseline.
4.
When
you
see
the
reading,
press
RELA.
Rel
A
appears
and
the
meter
sets
to
manual
range
5.
Take
a
measurement
for
another
component.
Rather than
the
actual
measurement
value, the
meter
will
display
the
component's
variation
from
the
baseline
(0.20.
0.01,-0.13,-0.02,
etc.).
If
the
measured
value
is
lower
than
the
baseline,
the
meter
will
show
a
negative
relative
value.
A
reading
of
0.00
indicates
an
exact
match.
»
To
stop
relative
measurement,
press
RELA
again
or
set
the
function
dial
to
another
setting.
Note:
+
Forthe
most
accurate
reading,
the
temperature
should
be
between
65°F
and
83°F
(18°C
and
28°C),
with
a
maximum
of
75%
relative
humidity.
Relative
and
baseline
measurements
MUST
always
be
in
the
manual
ranging
mode.
+
When
measuring
voltages
in
zero
offset
or
baseline
mode,
the
noise
of
the
environment
you
are
measuring
in
could
interfere
with
measurements.

Measuring
high

with
the

the

dial
to °C/°F.

Plug
the

~COM

plug
its

into
+V.mA.Q.
