Current
Measurement
Considerations:
Current
measurement
must
be
performed
in
the
temperature
range
of
0~40
o
C
(32
to
104
o
F).
When
pressing
the
trigger,
do
not
suddenly
release
it;
the
clamp
is
sensitive
to
magnetism,
heat,
and
mechanical
stress
and
such
impact
will
cause
the
reading
to
fluctuate
briefly.
If
the
reading
is
positive
in
the
measurement
of
DC
current,
the
direction
of
current
is
from
top
to
bottom
(meter
faceplate
is
the
top
and
the
meter
back
is
the
bottom).
In
order
to
ensure
measurement
accuracy,
the
conductor
measured
must
be
positioned
in
the
middle
of
the
clamping
area;
otherwise
additional
error
of
reading
of
±1.0%
(typical)
will
be
generated.
The
accuracy
of
non
‐
sinusoidal
waves
must
be
adjusted
as
follows:
Crest
factor
1~2,
accuracy
increases
by
3%
Crest
factor
2~2.5,
accuracy
increases
by
5%
Crest
factor
2.5~3,
accuracy
increases
by
7%
