OK, let's consider measurement error.
I have, let's say, a weight.
It actually masses 50 g.
I put it on a scale and observe that the reading on the scale is "51g."
On your account, is my observation false?
If so, does your judgment change if it's a standard weight that I'm using to calibrate the scale?
On your account, is my observation false?
Your observation of the reading on the scale is true, of course. Your observation that the weight is 51 grams is false.
The distinction between accuracy and precision is relevant here. I am assuming your scale is sufficiently precise.
does your judgment change if it's a standard weight that I'm using to calibrate the scale?
No, it does not. I am using "false" in the sense of the map not matching the territory. A miscalibrated scale doesn't help you with that.
