Mikromierz Usage: How to Accurately Interpret Micrometric Measurements?

I have such a micromirror:


It is equipped with a knob with a clutch, additionally in a fixed scale from 0 to 25mm and the second on the knob from 0 to 50.

I put in a coin, turn the knob to catch it and when it's already sitting I turn the knob of the clutch and after a while the device stops, showing the result on the scale.

Unfortunately, I do not know how to read it.
I do not know what is visible on the foto shifter and attached as a key to the whole set.

Measuring a 5gr coin will cause such a result:


The result is 1.15mm?

it is not too complicated

Apparently not but however. The older man, the more resistant to knowledge.
Earlier, I suggested a micrometer guide with 1/100 scale
and mine is 1/50 from earlier problems.

I modified the photo slightly by adding a line and marked it in a red circle.
I have to understand that in my micrometer if the measurement will be like on the current photo:


is the result = 1.00mm + 0.5mm + 0.15 = 1.65mm?

I know that the subject and the query may seem ridiculous but I'd rather make sure twice and ask a hundred how to later have problems especially that the micrometer is in my hands for the first time in my life and was purchased to measure the thickness of control plates in valves in the car engine. It's better to ask twice how to cry later.

From zero to 50

Well on the subject, Everything is clear. Thank you for the advice.
