Having a little trouble setting up the M-bar pressure sensor to my satisfaction.
I have it set to trigger an alarm below 370 kpa. If I boot up the Tx and turn on the plane with less than 370kpa in the tank, I get an alarm warning me of low air pressure (this is good so far). If I then fill the tank above the alarm threshold, cycle the gear a few times so it drops below, the alarm does not trigger. I can't figure out why, it's like it needs to be reset?
If I have sufficient air pressure in the tank when the plane is turned on, there is no alarm ( expected), then if I cycle the gear below the 370kpa, the alarm will trigger. If I top up the air and cycle gear again dropping below the 370kpa, the alarm will NOT trigger.
I'm assuming I have to assign a reset switch and that it will not reset itself? So once an alarm has been triggered, it must be reset manually?
Thanks
Mike
