Calibration steps must be performed in the following sequence, or an error will occur.
You can abort the procedure and revert to previous calibration constants before
:SAVE by sending the :CAL:PROT:LOCK command.
Calibration is performed on both channels at the same time — it is not possible to
only calibrate one channel.
Connect the Model 2306 to the controller IEEE-488 interface using a shielded interface
cable.
Turn on the Model 2306 and the test equipment, and allow them to warm up for at least
one hour before performing calibration.
Make sure the IEEE-488 primary address of the Model 2306 is the same as the address
specified in the program you will be using to send commands.
Send the following command with the correct code to unlock calibration:
:CAL:PROT:CODE '<code>'
For example, with the factory default code of KI002306, send:
CAL:PROT:CODE 'KI002306'
Send the following command to initiate calibration:
:CAL:PROT:INIT
Allow the Model 2306 to complete each calibration step before going on to the next
one. See Detecting calibration step completion in Appendix C.
Connect the OUTPUT #1 SOURCE, SENSE, and DVM IN terminals to the digital
multimeter, as shown in Figure
to DMM INPUT HI; SOURCE -, SENSE -, and DVM IN - to DMM INPUT LO.)
Send the following command to output 14V:
:CAL:PROT:STEP0 14
At this point, the source output is turned on and will remain on until calibration is
completed or aborted with the :CAL:PROT:LOCK command.
