I have a pm3384 and it keeps failing the autocal. I went through the manual calibration, and it was in need of that, but in the end it still failed with error d1a. I've read the service manual and cannot find any reference to this error. Wondering if anyone may know what d1a is and where to start looking.
The scope works for the most part, but when using cursors they are way off. Thanks
