NOTES
[1]
It
is
expected
that
many
users
will
wish
to calibrate
Range
gains
at
values other than the
nominals shown.
In these
cases
set the Calibration
Source voltage and
4708
OUTPUT
display to
in-house standard values near nominal.
[2]
Except
for
Step
2,
use
CAL
key
as trigger
(Refer
to
Calibration Routine).
[3]
To
trim the internal
Master Reference

'STD*
for
'SET*
for
1
V
or
lOV Range
(Refer
to
Calibration
Routine and
description
of 'STD*).
