Hello Mike, this booklet may help you with some of your questions. I haven't read through it for quite some time now, but as I recall it is fairly comprehensive and may be of some help. Best regards, aevald
Mike, I tried to attach a Calibration Booklet from Miller, but unfortunately I couldn't do so because of the size of the pdf. file, it was too large to attach. If you would consider PM-ing me and giving me your email address I can send it to you that way if that works for you.
