Regarding the alignment of mechanical pumps, I would like to ask the experienced technicians a theoretical question – I’m really too stupid to understand it

A dial indicator is used to measure the radial dimension, with the values being a1, a2, a3, and a4. Some people say that a1 + a3 must equal a2 + a4, but I’m really not good at this; I just can’t figure out why. Could anyone who is good at math explain it to me?
For the same axial readings S1, S2, S3, S4, I’ve also heard that S1+S3 is equal to S2+S4
If it’s a gap, then it should be a1-a3; I really can’t figure out what a1+a3 means
That’s impossible; as long as the readings on the gauge are not artificially defined, they will always be positive numbers. Four positive numbers cannot add up to 0
a1+a3 must equal a2+a4, which indicates a measurement error
