The first one didn’t have enough data points for my liking...... but at least you knew if something was way out to lunch or not.
Tha PAC calibration spring has loads listed for several lift points.
I use a lot of the same springs over and over, so I pretty much know what I’m looking for in terms of load/height from one of the “usual” springs.
I get out the calibration spring most often when it’s a spring I’m not familiar with....... and the observed loads don’t agree with the published specs.
The tester has always been fine...... the observed loads vs published specs?
Not always in agreement.
