TAG weather station repair
 

I have a TAG WSC-1 handheld weather station that has worked great for years. Got it out of trailer this season and it is not working. All the parameters seem correct, temp, Bp, humidity, etc. but the DA is not even close. We are at 7220' and the DA is showing between 150 and 250 feet. I have done new batteries, BP calibration, and no change. I know TAG is out of business but I am looking for someone out there that might be able to repair this. Thanks for any help.
