CALibration:ZERO:AUTO?
Colons separate the root command from the second level command
(
CALibration:ZERO
) and the second level from the third level
(
ZERO:AUTO?
).
Abbreviated
Commands
The command syntax shows most commands as a mixture of upper and
lower case letters. The upper case letters indicate the abbreviated spelling
for the command. For shorter program lines, send the abbreviated form.
For better program readability, you may send the entire command. The
instrument will accept either the abbreviated form or the entire command.
For example, if the command syntax shows
MEASure
, then
MEAS
and
MEASURE
are both acceptable forms. Other forms of
MEASure
, such as
MEASU
or
MEASUR
will generate an error. You may use upper or lower
case letters. Therefore,
MEASURE
,
measure
, and
MeAsUrE
are all
acceptable.
Implied Commands
Implied commands are those which appear in square brackets (
[ ]
) in the
command syntax. (Note that the brackets are not part of the command and
are not sent to the instrument.) Suppose you send a second level command
but do not send the preceding implied command. In this case, the
instrument assumes you intend to use the implied command and it responds
as if you had sent it. Examine the partial
[SENSe:]
subsystem shown below:
[SENSe:]
FUNCtion[:<
function
>]
FUNCtion?
RESistance
:APERture <
time
>
:APERture? [MIN | MAX]
:NPLC <
number
>
:NPLC? [MIN | MAX]
The root command
[SENSe:]
is an implied command. To set the
multimeter’s function to AC volts, for example, you can send either of the
following command statements:
SENS:FUNC:VOLT:AC
or
FUNC:VOLT:AC
