Does anyone know how to calibrate or test if a Jemeter Digital 90 is properly calibrated. I can’t find an owner’s manual. Any help would be very appreciated.
Hi Hayden see attached URL addresses this may help you calibrate
would not allow me to upload will try again
Okay lets see if this works
Thank you sydp,
I looked at both sites and they are very informative. Turns out my Jemeter is fine. It is however, very touchy just like the sites said. Some gems will simply need to be inspected by other means. I have other tools, but the Jemeter is so fast at narrowing the field.
