1.6.1
General
The
procedure
in
the
table
below
shows
all
that
is
required
to
completely
'AUTOCAL'
the
AC
Current
function.
lf
just
the
AC
Current
or
just
one
range
of
AC
Current
is
to be
calibrated,
then
steps
1,2,
11&

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.
lf
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
lkHz.
e.g.
Datron 4200
Autocal
AC Standard
with option
30.
1.6.3 Checking Accuracy
after
?UTOCAL'
To check
the accuracy
after
'AUTOCAL'
the
speci'
fication
Verification
section
of
the
Operation
Handbook
will
be useful.
lt
provides
tables for
quick
reference
of
accuracy
on all
ranges and functions in displayed
digits.
