Free air calibration ZT-2
Is there one? I can't find any reference to it in my paperwork but apparently the Innovative ones have it.

Re: Free air calibration ZT-2
the ZT2 doesn't require or use a free air calibration.
its part of the reason i went with the ZT2 instead of the Innovate.
i was worried that the ZT2 may not read as accurately as the Innovate, but after having used mine non stop for well over a year, it still checks out with the 5 gas analyzer at work.

Re: Free air calibration ZT-2
The problem with free-air calibration on a WB is that it only calibrates the lean side of the sensor. It is OK for a 'sanity check' of the sensor, but does fall short of a full sensor checkout.
IOW, if the free air check is OK, it doesn't mean that the sensor is OK on the rich side. But if the free-air check shows an issue, then there is a problem with the sensor (or electronics).
