just use a multimeter(preferrably digital) make sure you calibrate it to 0 first....
and you can touch 2 of the pins on the sensor to get your reading... I dont have mine off to tell you which pins.... its easy to figure out... just try them until you get a reading

you have to hold open the tb at the same time to get the reading...can be tricky if you do it yourself with only 2 hands...but I did it on my own...
