I have a pair of iGaging Absolute DROs that I installed on my little Rusnok mill, and despite having some issues early on, they've worked flawlessly for about two years. Upon replacing the batteries in one of them, the readout started acting a bit strangely. When reading in decimal inches, a move of .500" displays as .050". It seems to do this with repeatable accuracy, but obviously that ain't right, and I'm not willing to use it until I know I'm certain that it's reading properly. I emailed William Zhang, my previous contact at this company, and haven't received a reply yet (which is understandable, as I just emailed him), but a call to his phone number rang a LONG time befor if finally gave a fax tone, then hung up on me. A call to the number listed on their website rang a long time before Verizon service answered with a recording stating that the cellular number dialed isn't currently available. ...all of this makes me a tad nervous. Has anyone dealt with them recently, or have different contact info for them? Heck, does anyone just know how to solve my problem? I just want to get back up and running!!!! Thanks in advance, gang.
