Seneye Reef Monitor Parameters wrong - trimming settings?

[figwig]

Hey all - I recently got a seneye reef monitor, and after soaking the slide for 48hrs and putting it in the tank I've been a little surprised as it's readings are way off. My pH according to 2 different test kits is 8.3, but the seneye says 7.5, and my ammonia (new tank cycling so expecting it to be high at this point) is around 1.2ppm nh3+nh4 (calculated roughly 0.12 just nh3) but the seneye says 0.05ppm.
I've already put another slide in to soak so I can test that one (waste of a few quid if it doesn't help) but I noticed that there are some trimming settings available. I couldn't find anything online about how best to calibrate these or if I should even have to in normal circumstances - so I wanted to ask, has anyone else had to trim out their seneye reef monitors? Are they accurate at all? Could I have got a dodgy unit?
Thanks,
Will

I can’t answer the specific question, but I can bump the thread to see if we can get you some help

I found this issue with the ph aswell. If you have selected in the settings "tick for reef tank" or whatever it says. Untick it, that fixed my issue

We have a thread on fixing those initial misreads at least for the ammonia one:

A thread tracking the incidence of seneye nh3 misreads

https://www.reef2reef.com/threads/using-seneye-reef-readings-to-cycle-tank.773299/ there are two more, I want to log these in one thread so we can begin patterning. I’ll go find the others in no way does that reef above have tenths ppm nh3 but thats not been proven, yet.
