Is the 1% accuracy relative to the max load (e.g. +/-5 N for the 500N model) or to the force being measured at any given time?

The 1% accuracy is relative to the max load (e.g. +/-5 N for the 500N model).

Can I set this gauge for 1, 2, and 5kg loads for push-pull testing to adjust belt tension?

Yes, you can do a load push-pull test by setting an upper limit. But only one upper limit value can be set at a time.

what is the minimum load that can be measured with the 300N and 500N gauge ?

The minimum load of 300N and 500N gauge are 0.1N/ 0.01kg/ 0.01lb/1Oz

How can i calibrate this? the instructions says zero and full scale. does that mean i enter it when at zero weight and then again at 500n (500n unit)?

Calibration requires standard parts (for example, 500N model requires 50kg standard parts, like weights). You can also use professional calibration instruments to calibrate. Do not calibrate yourself without professional instruments and standard parts.

Great!

Using it to pull-test adhesion of glass fused to brick. Does exactly what I need holding the highest break-away reading. When I worked in the semiconductor industry I had to make my own recording pull-tester using a bathroom scale and computer to test thin film adhesion to silicon wafers. Wish I had one of these then!

Excellent tester

I needed a small handheld pull gauge for work (non destructive testing) so I figured I would give this a try. I’m testing to 70lbs so this tester fit that need. Easy to set up, easy to grip and easy to see the display. Good case and accessories that comes with the tester and is very accurate (had unit tested in a lab for accuracy). Overall this was a great purchase
