Compensation
Following
adjustment
must
be
conducted
when
the
probes
are
connected
to
any
input
channel
for
the
first
time,
so
that
they
can
be
matched
with
the
input
channel.
Probes
that
have
not
undergone
such
compensating
correction
may
result
in
measurement
error
or
wrong
measurement.
In
case
you
need
to
adjust
the
probe
compensation,
please
follow
the
following
steps:
1.
Set
the
attenuation
coefficient
in
probe
menu
to
10
×
and
turn
the
switch
on
the
probe
to
10
×
,
and
then
connect
the
probes
to
channel
1.
In
case
hook
heads
are
used
on
the
probes,
they
should
be
ensured
to
have
reliable
contact
with
the
probes.
Connect
the
tip
of

you
can
use
an

Warning:
To
avoid
electrical
shock
when
probes
are
used
in
measuring
high
voltage,
please
ensure
that
their
insulated
wire
is
in
good
condition
