(grey)
probes
Purpose: determine
the gain,
using
a
10:1 probe.
Calibration
equipment:
Red
scope probe
(delivered with the
ScopeMeter)
Qrey scope
probe
(delivered with the ScopeMeter)

Calibration setup:
IMPORTANT:
Calibration
steps
M19
and
M20
determine
the Internal calibration
constants
that
compensate
for probe
cheractenstics.
To achieve
full
accuracy
(a$
listed
In
the
specifications
in
chapter
2)t
calibrations
Ml
9
and
M20 must
be performed, using
the
probes
that are normally
to
be used
with the instrument.
If
the
probes
delivered with the ScopeMeter
are not
available at
the time
of
calibration,
use other probes
specifically
designed
for
the
ScopeMeter.
In this
case you
must
notify
the user
that
these
calibrations
have been
performed,
using
different
probes.
To
achieve
full
accuracy, the user
must
do
a
User Probe
Calibration,
using his
own
probes. This procedure
Is
described
in
the
ScopeMeter
Users Manual. Because
