What isthe purpose of vertical markings?

[@MrRICHARDGOMEZ]

why 90 and 270? why not 0 and 180? thanks for this video. hope you can clarify on this.

[@phil_boucher]

It's the vertical angle, 0 is towards the sky, 90 is in front of you, 180 on the ground and 270 behind you

That's within 0.025% accuracy. Very nice fine instrument.

[@myozone]

That's a >50 second error - sounds big to me.?

[@hectormunoz4812]

If its over 10 mil then how can we correct it?

[@phil_boucher]

It would need to be calibrated in a shop

[@olazzeedris5535]

Thanks so much for educating

Hold it !. I didn't get why he had to set it a 270 degrees after setting the 90 degrees.

[@olhashea8070]
