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.
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.
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 ?

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