I've tried. They were expensive too - $2 for that tiny thing..

I'll try. I have an expensive digital multimeter myself, but a digital
meter is not any good in measuring pulses..

The sensors are incredibly expensive (about $200), so I'll rather not
replace them if I don't have to.. :-)

I'll try your tip about measuring AC, I haven't thought of that
before..
