The
OUTPUT
display
is
supplemented
by
legends,
which
always
indicate the correct units for the
Range and
Function
selected
Output
and
Display Control
Each
vertical pair
of
1 4
keys
is
assigned
to
the display
digit
above
it.
Thus
the
value
registered
on
the display
may
be
set
within
the
range permitted
by
the function
selected.
Each
momentary
press
of
the
t
key
adds
1
to
its
digit:
pressing the 4
key
subtracts
1
.
If
OUTPUT
is
ON,
the
Output
terminal value
is
also
changed by
the
same
increments
as the display (subject
to
the
instrument
interlocks).
On
Q.
ranges,
only
the
overrange
(leftmost pair
oO
1 4
keys
are
operative.
These
duplicate the action
of
the
Full
Range/Zero
Keys.
The
Resistance value displayed
is
the calibrated
value of
the
standard
internal resistor
selected (not the
nominal
value).
This
may
be updated
during periodic
calibration.
The
value
dis-
played depends on
the selection
of
Local
(2-wire) or
Remote
(4-
wire) Sense,
and
should
be
recalibrated
in
the correct
Sense
mode
(See Section
8).
