Re: NTK L2H2 New Linearisation
Only the L1H1 has a calibration resistor - NTK L2H2, and I imagine the Walkers copy, do not have the calibration resistor. The L2H2 - IIRC - supersedes the L1H1 and is supposed to be more consistent between sensors, albeit with a very slightly different calibration curve to the L1H1. The best thing ...

Re: Rotary switches for calibration changes, type question
For me, that's the nail in the coffin for diodes. I spoke with Pat the other day and I'm pretty sure he said the pullup was 3k3, by the way. The only argument for using diodes is if the voltage at the top of the chain is unknown. So for a universal selector switch there is a case for diodes but wher...

Re: NTK L2H2 New Linearisation
I see Ryan has posted the linearisation, saying it's a "walkers" sensor: so not a genuine NTK.
I'm assuming, therefore, that the genuine NTK I have - and sell - has the correct linearisation by default, and you do not need to use the new one

Re: NTK L2H2 New Linearisation
Also, when I load that linearisation in to SCal 2.11.38 it is a flatline lambda=5. The file looks OK, but doesn't seem to work for me it seems.

Re: NTK L2H2 New Linearisation
The sensor in mine, bought/fitted this year, and the same as those I supply, are marked/sold as LZA-09-E1. Mine was pretty much spot on compared to an Innovate LC-1. What is the exact identification on the "L2H2" sensors from Charlie? It would be useful to know if there's something to diff...

Re: Rotary switches for calibration changes, type question
6xIN4148 diodes would be a 6*.65=3.9V drop (approx). 1.1V across 330R would be about 3mA, so, yes, that would work fine.
A 10k would be 0.1mA which would also work.
So, what didn't work in your test?
And, sorry for the dumb question, but you did connect the diodes the right way round I presume?

Re: Stack data stream addition
The Syvecs team will need to confirm, but I think you may find that there's an update on its way that will provide a whole heap more info via RS232. Not necessarily an update to the existing STACK stream, but via RS232 nevertheless.

Re: Rotary switches for calibration changes, type question
IN4148 diodes, and I would think something like a 10k pullup, but I don't know for sure.
