5.4.7 Calibration Commands and Queries
The calibration command provides the user with a method of remotely
initiating a calibration and setting or querying for various instrument
settings associated with the calibration function. The
< selection > value
indicates that a value of 1 , 2 , 3 , or 4 should be specified to indicate which
calibration is to be modified or queried of the four possible calibrations for
each input.
•
CAL:UNLOCK < cal_passcode >
With the valid passcode sent as an argument, the command unlocks the
calibration for modification. The calibration remains unlocked until the
CAL:LOCK command is sent, the instrument is reset, or the power is
cycled.
•
{A|B|C|D}:CAL:LENgth < selection >,< active_length >
Sets the active length for the sensor input and calibration selection
specified. The remote units must be either centimeters or inches in order
to specify an active length value.
For example, the commands:
UNITS 1; B:CAL:LENGTH 2, 100.0;
would set the active length for sensor input B , calibration selection 2 , to
100.0 inches.
•
{A|B|C|D}:CAL:LENgth < selection >?
Returns the active length setting for the specified sensor input and
calibration selection.
•
{A|B|C|D}:CAL:PERform < selection >,{MIN|MAX}
Performs a MIN or MAX calibration for the specified sensor input and
calibration selection. The instrument will beep once if the calibration is
successful. Two beeps indicates that either the new MIN point is greater
than the previous MAX, or the new MAX point is less than the previous
MIN.
•
{A|B|C|D}:CAL:ACTIVE < selection >
Sets the active calibration for the specified sensor input. The calibration
must be valid, i.e. at least one MIN and MAX point should have been
previously set.
•
{A|B|C|D}:CAL:ACTIVE?
Returns a single digit: 1 , 2 , 3 , or 4 . This indicates which calibration, of the
four possible calibrations, is currently selected as active for the specified
input.
