2-20 Calibration
* Step numbers correspond to :STEP commands.
Step 3: Program calibration date
Use following commands to set the calibration date:
:CAL:PROT:DATE <yyyy>, <mm>, <dd>
Note that the year, month, and date must be separated by commas. The allowable range for
the year is from 1997 to 2096, the month is from 1 to 12, and the date is from 1 to 31.
Step 4:Save calibration constants and lock out calibration
Calibration is now complete, so you can store the calibration constants in EEROM by sending
the following command:
:CAL:PROT:SAVE
NOTE Calibration will be temporary unless you send the SAVE command. Also, calibration
data will not be saved if (1) calibration is locked, (2) invalid data exists, or (3) all
steps were not completed in the proper sequence. In that case, the unit will revert to
previous calibration constants.
After saving constants, lock out calibration by sending :CAL:PROT:LOCK.
