I spent some of today attempting to calibrate a 7081 that has had the EAROM chip (ER3400) on the in-guard (floating) logic board replaced.
For each calibrate command issued I get a "Cal Incomplete" message rather than a "Cal OK" message (this *may* be OK, or *may* be a fault). When I try to issue calibrate, reference, 10.00000 I get a message "Factor out of range" (all other VDC, VAC, and KOHM calibrate commands worked apart from the Cal Incomplete message). Does anyone know what the problem is, or have any thoughts as to what the probable cause might be? On a very related point, how do you calibrate the Ratio calibration constant (there's nothing in either the Service manual or the Test Specification about this other than item 21 in the automated checks section on page 16 which says: 22. Ratio - ratio is calibrated.
