Query
response:
NULL
<number>;
Discussion:
This
command enables the NULL function; the argument
(in volts or ohms) specifies the vaiue of the offset. This value
can
be
any
number up to 100% of the range.
The
NULL
function is disabled when the measurement
function
is
changed or when
the argument is 0. (Changing
the measurement function also sets
the argument to 0.)
WARNING
The header
selects the OHMS function; the argument
selects
the range.
The format for numeric arguments is de
scribed
under
Number Format later in this section of the
manual. The argument can be any value; however, the
in
strument
rounds
the argument up to the first full scale
range.
For instance, for
an argument of 100, the instrument
selects the
200 Ω range.
If
the
argument is omitted or its value is 0 or less, the
instrument auto-ranges
beginning at the highest
range.
If
the
argument is above the highest range, the instru
ment generates
a command error (and asserts
SRQ if RQS
is
on).
Use
caution when
the
NULL function is enabled, since
the
measurement may
not indicate
the value
of the
voltage
applied
to
the
input connectors.
