It’s finicky and tedious work. I recommend getting a Jointer Pal or some equivalent jig. It’ll turn that 10 hours of frustration into just two hours of frustration.

Two ways depending on what tools you have availabe to you.
As you preform this operation be sure to slightly rotate the power head by hand to reach the “High” spot of the knife.
1- A dial indicator on a non-magnetic base.
With your jointer disconnected from the power source.
Insert the knife into the power head and adjust the set screws to make the knife on the same plane as the outfeed table. Do this with each blade at the same (equal) height.
2- Using two flat pieces of steel. Positioned them on the outfeed table above each blade adjusting screw.
Using a feeler gage ($6), set the blade using the thinnest one. It will have a better feel if you remove it from the set.
Upon setting the blades be sure to check the torque of the lock screws.
This is a good time also to verify the perpendicularity of your fence. A good combination square head will be best for this.
When you complete either one of these methods run a couple sample cuts and see your results.
Take your time and double check your work. I doesn’t have to be NASA grade.
Always work safe.
Good luck.
PM me if you like.

Jointer knives don’t have set screws, they have gib screws. A 30-year journeyman who hasn’t achieved master might make that mistake though.

Back to the OP, take Matt’s advice and spend a few dollars on a jig. It’ll make your life much easier.

Jointer knives can be challenging. It can take many hours until you figure it out.
Everyone has their favorite way.

IMHO – Best jig for jointer knives setting is a Jointer Pal (or one similar):
https://www.woodstockint.com/products/W1211A/Jointer-Pal-Standard-4-8-
It has magnet to hold the blade level and makes setting the out feed table to cutter head 100x easier.

Another style jig that uses a dial indicator is explained in this bog series:

I use a DIY rotocator to double check my height after using the jointer pal.

Best Luck.

I can do my 3 knife head in under 30 minutes with a dial indicator. If you find yourself in a spiral, PM me and we’ll get it set.

After getting the idea here I ordered a pair of 1 2 3 blocks and used a 4” threaded bolt to attach the gauge I bought at HF. I ended up needing a flatter end for the dial gauge so you would be better off getting it on amazon as the gauge with the tip set included. Get the dial with a needle and not the digital style so it is easier to see the subtle change.

I also use a dial indicator with button tip. Hopefully the op doesn’t have a craftsman jointer with the fixed outfeed.

This will show you how to do it with a simple shop made jig. I’ve found it to work good on my 6” jointer.

That is what I have. A Craftsman with a fixed outfeed table but the jig worked perfectly.

I have had success just attaching a neodymium magnet to a non-stainless steel ruler and using that as a jig. Sort of a poor man’s jointer pal. Set the ruler on its edge on the outfeed table with magnet on the ruler near the blade and the ruler will magnetize just enough that it will hold the blade at the proper height. Do one end, then the other and go back to check the first end just to make sure it is right. You might have to go back and forth a couple of times but I find this easier than using a dial indicator.
