The default Option is to auto-adjust the calibration, which will take a reading and subtract it from
zero (since you're horizontal...). This is what you should choose if you are going to fly. When
you click on "Calibrate", the accelerometer offset will be calculated and it will be used from that
point on until you reset the power; you will be then be returned to the Status Page.
You can also click the down tick next to Option and select "Zero Offset"; that will zero the
offset, allowing you to see what the uncorrected Accel value will be on the Status Page. If you
do that, you will need to go back to the Calibrate link and select Auto-Adjust; the Proton WILL
NOT ALLOW YOU TO ARM if you select Zero Offset. It's strictly for your edification...
sometimes it's interesting to see how far the accelerometer has drifted.
Arming Your Proton
In order to start a flight, you need to arm the Proton. For safety reasons, the Proton will not self-
arm; that is, you must go to the Status page and arm it by entering the current Validation Code in
the text box and clicking on the Arm button for the flight sequence to begin. This is different
than most other flight computers, which will automatically go into an arming sequence a short
time after powering up, assuming that the continuity is OK. The Proton is a little bit different
because it's assumed that you're not using a power switch so you are basically using the arming
sequence as a remote switch. This is the reason why we have the dual-ended switching
architecture; it ensures that your ematch/igniter is essentially "dead" until the Proton has been
armed AND you have a flight in progress. This virtually guarantees that you cannot fire a
deployment charge (or an airstarted motor...) on the ground.
Before you can arm the Proton, any enabled deployment channels must be in a flyable status.
This means that if a channel is enabled there must be continuity; if a channel fails the continuity
test then you will not be able to arm your Proton. You can tell very easily from the Status page if
it's ready to fly, because any failed channels with have the continuity status highlighted in RED.
Note that if you've selected a servo deployment option the status will always be in GREY; there's
really no way to tell if a servo is connected or not, because they're an output-only connection.
It's assumed that they are always in a flyable state.
