Did they give you a quote for calibration? Did you test it out so you would know if it was off, because I wouldn't be surprised if it was still dead on. Just thought it would be interesting to see,https://www.custom-cal.com
This is who is refurbing mine. Give them a call.
I`m sending it to a repair shop to have it gone over and calibrated.
not bad for freeIt has a problem with the on/off switch, but did light up. I sent it to a repair and calibration shop. They are going to fix that, check it for bad caps etc, and calibrate it.
