HygroSet II digital problem... Help!

[AlohaStyle]

Hey guys,

I bought a digital HygroSet II hygrometer from CI last month which is the adjustable kind. I salt tested it a couple times to make sure it was an accurate reading and when I went to turn the adjustable knob to make it read 75%, the number wouldn't change. I pulled the battery out a few times to reset and tried a bunch of things, but no luck.

I contacted CI and just got a replacement. After doing another extensive salt test, I tried adjusting to 75% and it isn't moving again! I turn the knob but the number doesn't change. I haven't pushed the "lock" button at all and reset it again with no luck.

Am I doing something wrong? Is there a trick I don't know about? I'm pretty pissed but was wondering if I need to do something the instructions aren't saying.

I need to get my Edgestar running to perfection before my ChasDen trays come in!?!

Please help and thanks for any responses!
