integer or floating point form, or in engineering/scientific notation. The IEEE-488.2
standard uses the names NR1, NR2, and NR3 respectively to denote "integer",
"floating point", and "scientific notation". For example the number "twenty" may
be represented by any of the following ASCII strings:

Numeric Parameter Formats
Integer
Floating Point
Scientific Notation
For more information on these definitions, refer to the IEEE-488.2 standard.
There are no default values for omitted parameters. If a command is expecting a
parameter and nothing is entered, an error is generated.
For further clarity in programming, the Boolean values of one (1) and zero (0) may
be used or their names as indicated below.

If multiple parameters are expected, they should be separated by commas. For
example, to set the Steinhart-Hart constants for temperature measurement (C1,
C2, and C3) the following command could be sent
LAS:CALT 1.111, 2.004, 0.456
All parameters of a multi-parameter command must be entered, even if only some
of them need to be changed. For example:
LAS:CALT 1.111,
will generate an error. The second parameter must be included.
