For the best results when using a stylus type indicator, you should not depend on the indicator as a measurement device. Cosine error is too variable depending on the swing of the tip. I always recommend using the machine or i.e. graduated height gage for the exact measurement. A stylus indicator is technically only a comparative tool, not a direct tool.
In most average cases, it's not a big issue, but when working with very high standards, it should be noted. BTW, the term gage and guage are 2 different meanings. A gage is the referenced tool, guage is the action of using a gage. (For the spell checker.) I use a tire gage to guage my tire pressure.
Excellent example of real world use for eliminating cosine error.
Great video for keeping in touch with the basics of indicator reading!
I just started the video but my first thought is that I hope I will never start the machining centre spindle after checking for runout on a part.
If you are in machining long enough, you'll get your chance. (Been there done that)..
are those indicators outsourced from HAAS ?
I'm not so sure about that 9.03mm read out. I'll say that was a 8.97mm read out. Since the dial didn't make 9 full rotations, it came 3 graduations short. Even both are within tolerance, that's a huge mistake.
It's 9.03mm. The large dial increases in clockwise direction (black numbering) and went for slightly more than 9 rotations. The tiny dial with whole millimeters increases counterclockwise though.

Please use sae calibration. Yes I can calibrate, but stop being so Smart. Tutor.
Haas is still doing business with Russia 👎. I'll pass.🇺🇲🇺🇦
