14-12 Calibration
Remote calibration procedure
Use the following procedure to calibrate the Models 2306. Table 14-3 summarizes the
calibration steps in the proper sequence. See Appendix C for command details.
NOTES Calibration steps must be performed in the following sequence, or an error will occur.
Y
ou 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.
Step 1: Prepare the Model 2306 for calibration
1. Connect the Model 2306 to the controller IEEE-488 interface using a shielded interface
cable.
2. Turn on the Model 2306 and the test equipment, and allow them to warm up for at least
one hour
before performing calibration.
3. Make sure the IEEE-488 primary address of the Mod
el 2306 is the same as the address
specified in the program you will be using to send commands.
4. 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’
5. Send the following command to initiate calibration:
:CAL:PROT:INIT
Step 2: Perform Channel #1 (battery channel) calibration steps
NOTE Allow the Model 2306 to complete each calibration step before going on to the next
one. See Detecting calibration step completion in Appendix C.
1. Connect the OUTPUT #1 SOURCE, SENSE, and DVM IN terminals to the digital
multimeter
, as shown in Figure 14-1. (Connect SOURCE +, SENSE +, and DVM IN +
to DMM INPUT HI; SOURCE -, SENSE -, and DVM IN - to DMM INPUT LO.)
2. Send the following command to output 14V:
:CAL:PROT:STEP0 14
NOTE At this point, the source output is turned on and will remain on until calibration is
comple
ted or aborted with the :CAL:PROT:LOCK command.
