Recoil spring weights?

[johnl]

How do you measure a recoil spring weight? Is it as easy as getting digital scale and compressing the spring and read the display? How do you hold the spring if it’s a long bastard. I need to verify something before I shop

Brownell's sells one that works with a digital luggage scale.
