CALSTR
Description Calibration String (remote only). Stores a string in the multimeter's
nonvolatile calibration RAM. Typical uses for this string include the date or
place of calibration, technician's name, last CALNUM value, or the
scheduled date for the next calibration.
Syntax CALSTR string[,security_code]
string This is the alpha/numeric message that will be appended to the
calibration RAM. The string parameter must be enclosed in single or double
quotes. The maximum string length is 75 characters (the quotes enclosing
the string are not counted as characters).

you must include the security_code in order to write a message to the
calibration RAM. (You can always read the string using the CALSTR?
command regardless of the security mode). Refer to the SECURE command
for information on securing and unsecuring the calibration RAM.
