bits
can
be controlled
with this
key.
When

NUMBER" becomes
the active
function.
This
active
function must
be entered
through the
keypad number
keys
,
followed by
the 4

5 key
. The
bit
is
cleared
when
the

is
pressed.
Entering
numbers
larger
than
7
will
result
in
bit
7
being
cleared,
and
entering
numbers
lower
than
0
will
result
in
bit
0
being
cleared.

converts
the

parameter has been dened, it is shown in brackets under the
softkey label. If no conversion has been dened, the softkey
label reads

error correction on or o. The analyzer uses the most
recent calibration data for the displayed parameter. If the
stimulus state has been changed since calibration, the original
state is recalled, and the message \SOURCE PARAMETERS
