Interface Commands
Note
When you send a command, preface the command with either a C: (cold side) or H: (hot side).
If the C: or H: are left off, the returned value is for the hot side.
The various commands to access calibrator functions through the digital interface are listed in this
section (see Table
). These commands are used with the RS-232 serial interface. Terminate the
commands with a carriage-return character. The interface makes no distinction between upper- and
lower-case letters, hence either can be used. Commands can be abbreviated to the minimum number
of letters which determines a unique command. A command may be used to either set a parameter or
display a parameter depending on whether there is a value sent with the command following a
=
character. For example
,
s
<
CR
>
returns the current set-point and
s
=
150.0
<CR> sets the set-point to
150.0 degrees.
In the list of commands in Table
, characters or data within brackets, [ and ], are optional for the
command. A slash, /, denotes alternate characters or data. Numeric data, denoted by
n
, can be
entered in decimal or exponential notation. Characters are shown in lower case although upper case
may be used. Spaces may be added within command strings and will simply be ignored. Backspace
(BS, ASCII 8) may be used to erase the previous character. A terminating CR is implied with all
commands.
