false readings

Post by Aore Adventures »

gday guys from time to time we get false reading like today showing the generator running as well as a high corresponding load

the generator did not run at all and the load was minimal at the same time

what causes this and how to stop it from happening?

thanks for the help

Can we assume your OpticsRE is configured properly?
Maybe one of the OB techs can check their end. Would need your Optics site info in profile.

What version of firmware are you running on the Mate3s? Known issues with some down-level firmware on OpticsRe interface.

Does it show the spike locally on the Mate? If you have logging to an SD card enabled, you could compare what the Mate is seeing vs Optics..
