Using Minimum and Maximum
In the following example, Minimum and Maximum are offered as
alternative choices to declaring a specific parameter value.
The string CAL:CURR:LEV MIN sets the current calibration level to the
minimum model value.
Using Queries
A question mark lets you query the present value for most parameters. For
example, to query the current calibration state use:
You can also use the following to query minimum and maximum allowed
values for most parameters:
Important:
response before trying to read the second. Otherwise, you may receive an
incomplete first response followed by a complete second response. To avoid this,

the choices found within the braces.
Angle brackets ( < > ) identify where specific values must be entered
for a parameter. For example, in the example at the top of the page,
the parameter <current> appears in the command string. To set the
current set point to 0.1A, the syntax is CAL:CURR:LEV 0.1.
Square brackets ( [ ] ) identify optional parameters. If an optional
parameter is not sent with the command string, a default parameter is
sent in its place.
