EMS Sensor Bug?

[n223rv]

So I am setting my parameters on my EMS sensors for pitot heat. I was setting it for 0-5 volts it shows black, then 5-20 volts it shows red. The default screen said 0.0-30.0. Once I set it to 0.0-5.0, I lost the first numeric digit, and now I can't change the voltage to anything over 9.9 volts. I can only enter 2 digits. Is this a bug or am I missing something?thanks

It looks like there might be a small bug in that 30V isn't actually a valid voltage for any of the inputs. Fundamentally, they measure 0-5V, and anything higher than 5V is simply 5V. So if you're looking for pitot heat indication, set it for 0-2 and 2-5, and then you'll get what you're after. Note that our pitot heat indicator light circuit is grounded whenever the heater is powered off or something is detected as broken. This is patterned after the FAA requirements for pitot heat annunciation in type certificated aircraft
