Question
Why does my QBD1200 read 1000 ppb for all samples?
Summary
QBD1200 1000 ppb reading for all samples.
Answer
There is a demo mode on the QBD1200 that is initiated with the RSM log-in password. If an RSM or customer does not log out of the demo, all samples will be read 1000 ppb. To correct either log out and then back in with a different password or create a different login.
