I recently picked up a 1281 that is throwing a couple of errors. While researching the problem, I looked for the SelfCAL description and did not see anything conclusive. I will pull out my schematics and see if there are any references to a particular module. I was under the impression they were using the second LTZ1000 reference module for this function but was never certain.
I have the full repair manuals of the 1281 from Manuals Plus before they stopped selling. I will look up anything I can find this evening.
