CALibration:PROTected:DATE <yyyy,mm,dd> Saves last calibration date.
CALibration:PROTected:NDUE <yyyy,mm,dd> Saves next calibration date.
CALibration:PROTected:COUNt?
CALibration:PROTected:SOURce <NRf>
CALibration:PROTected:SENSe <NRf>
CALibration:PROTected:GUARd:STEP1 <NRf> Voltage reading for guard calibration step 1.
CALibration:PROTected:GUARd:STEP1:INIT
CALibration:PROTected:GUARd:STEP2 <NRf> Voltage reading for guard calibration step 2.
CALibration:PROTected:GUARd:STEP2:INIT
CALibration:PROTected:WAVE:STEP1
1. CAL:PROT:CODE "<string>"
This command sends the calibration password/code to unlock calibration. The
code is an eight-character string that must be enclosed in single or double
quotes. The Model 6220 default code is KI006220; the default Model 6221
code is KI006221. You can change the code once calibration is unlocked by
sending a different code with this command. However, if you change the first
two characters to something other than "KI", you will not be able to unlock cal-
ibration from the front panel.
2. CAL:PROT:LOCK
This command locks out calibration. Note that the CAL:PROT:LOCK? query
will return a 1 if calibration is locked; 0 otherwise.
