Been working fine so far. It's been sitting in my closet in the case and I just took it out to test a new piece of uranium glass I bought. When I turn the unit on, it instantly gives a constant beep (as well as a secondary beep noise). Light stays solid red. Also begins malfunctioning by showing an insanely high reading. Toggling the alarm off or trying to do a factory reset did nothing and it would appear that it's not accepting any inputs either. Battery showing full charge. No damage to unit. Any ideas or should I call for warranty support? Thanks [/quote]    Insert an Image File Check here to include your profile signature.
