Wildman,
There was a software change right after the start of production, to address a false zero reading. I'll bet yours was from the initial run. Please ship it in and we will reprogram it, test it and return it.
Please ship to:
ISSPRO, Inc.
2515 NE Riverside Way
Portland, OR 97211
Attention: Michael Pliska
Sticky,
Is yours an EV2 as well? If so, the same thing may apply.
Regards,
Michael Pliska
