1.6.1
General
The
procedure
in
the table
below shows
all
that
is
required to
completely
'AUTOCAL'
the
AC
Current
function.
If
just
the
AC
Current or
just
one range of
AC
Current
is
to
be calibrated,
then
steps
1,
2,
11
&
12
of the
Option 10
AC
Voltage Calibration table
must
be carried
out
first.
Then on
each range just a 'Zero'
and
'Gain' calibration
is
required.
If
the
'DVM
Reading After Calibration'
is
not
in
accordance with the table
then repeat operations of the
same
'CALIBRATE'
key
is
permissible to
improve
the
reading.
1.6.2
Equipment Required
An
AC
Current
calibration
source at
1kHz.
e.g.
Datron
4200
Autocal
AC
Standard with option 30.
1.6.3
Checking Accuracy after
'AUTOCAL'
To
check the
accuracy
after
'AUTOCAL'
the speci-
fication Verification section
of the Operation
Handbook
will
be useful.
It
provides tables for
quick reference of
accuracy
on
all
ranges
and
functions
in
displayed
digits.
