Step 4: Program calibration dates.
Use following commands to set the calibration date and calibration due date:
:CAL:PROT:DATE <year>, <month>, <day> (Calibration date)
:CAL:PROT:NDUE <year>, <month>, <day> (Next calibration due date)
Note that the year, month, and date must be separated by commas. The allowable range for
the year is from 1998 to 2097, the month is from 1 to 12, and the date is from 1 to 31.
