General
The procedure in the
table opposite is all that is
necessary to
completely 'AUTOCAL' the AC
voltage
function.
On
each range just a 'Zero', 'Gain' and
'AcHf'
calibration is
required.
If
the 'DVM Reading After
Calibration' is not in
accordance
with the
table,
repeat

Checking Accuracy after
'AUTOCAL'
To
check the accuracy
after 'AUTOCAL' the
'Speci-

section
of the Operating
Handbook
will be
useful. It
provides
tables
for quick
reference
of
accuracy
on all ranges
and
functions
in
displayed
digits.
