Fuel injectors nm?

I took out my fuel injectors, now I want to put them in, the torque wrench has weird numbers on it.
I have read that 22 nm torque is what I need but that's at the top of my scale on a Pittsburgh ratchet torque wrench?
I know this is just a simple misunderstanding.
Shine some light on this.

Is your wrench 1/2 or 3/8 in?

Every torque wrench has an effective range of measurement. The ideal usage places the needed torque in the middle 50%. Readings at the beginning or end of the scale are not as accureate.

Best to get a torque wrench where your needed torque is somewhere near the middle of its range.

I have 3 different sized torque wrenches, and sometimes i wish I had a fourth.
