AFR calculation / UT Comp Pro Zadatech AFR

Postby Carbonskin » Sat Feb 29, 2020 8:39 pm

Hi,

I bought the UT-Comp Pro and the AFR Wideband Probe by Zadatech (Manual: http://zada-tech.com/dyn/zadatechwidebandafr.pdf)

Can somebody help me with the recalculation? The manual says: "To convert from voltage to AFR use
the formula: V*15.04/5+7.35. "
What values should I put in "a" and "b" in UT Comp?

Thank you in advance for help.. 8-)

Manual says 7.35 AFR to 22.39 measurement range for 0-5V output,
so 0V = 7.35AFR and 5V = 22.39AFR,
using excel formula from 1st post in this topic: viewtopic.php?f=28&t=58
it will give
a = 3,01 and b = 7,35
