I tried putting an ohm meter on it, but a moving a magnet around it doesn't make it change.
Can I test this without applying power?

ther maybe a way the experts know but according to datasheet you would want to apply 8-12 v on pin one and expect to see output on pin 3 at 2-5v depending on Gauss applied

It won't. It's an IC and needs to be powered.
