Taking
Relative
Measurements
The
meter
allows
you
to take
relative
measurements
for
certain functions.
This
allows
you
to
measure
very
low
resistance
or
identify
closely
matching
measurements.
This
feature
is
not
available
for
°C/°F,
dBm,
9),
©,
LOGIC,
and
hgg.
Using
Zero
Offset
as
Reference
The
lowest
scale
on
this
meter
is
400 ohms
and
the
resolution
is
1/10
of
an
ohm.
With
lower
resistances
(for
example,
a
1
ohm
resistor),
the
resistance
in
the
meter's
test
lead
can
produce
a
reading
error.
The
zero
offset
feature
subtracts
any
resistance from
the
meter
leads.
1.
Select
the
function
(not
°C/°F,
dBm,
9),
DF
LOGIC,
or
hg).
2.
Select
the
600Q
range.
3.
Measure
the
zero
offset.
For
capacitance,
disconnect
test
leads.
For
other
functions,
touch
the
test
leads
together.
