CALIBRATION

Yeah, altimiters are required to fall within the limits specified by this table (up to the ceiling of the specific aircraft being tested):

Hopefully Bob will give a similar report (assuming Bob is the one that does the trouble shooting).

Later!!

The Photos didn't open in the last post so I'm try to just post the pic.





Thanks

The issue isn't whether the sensor is level, Richard, it's whether it's installed the right way up. Can't tell from the pic since it's shrouded with fire sleeve.

Bob, you want to weigh in here on which way up is proper? I can't tell from the pic.

As to the KX165 issue; I do apologize, but I am not going to take responsibility for wiring your airplane. The EFIS is working as designed. We can send someone out to straighten out whatever the issue may be, but fencing on the Internet is a colossal waste of time and I don't think I'll participate in any more of it.

I have had another EFIS driver graciously offer a free airline ticket to BMA to send Bob out to you to get this solved, which I think is the best solution.

Talk about a fantastic community of builders ...

We can discuss Monday.

Richard,

I have been using flow scans for a while on UAV's to measure very low flow rates. These sensors use an LED and optical reciever and create a square wave by passing "ticks" from the spinning turbine through the light beam. The units are very sensative to both orientation (causing air entrapment ... wires go on top) and vibration (depending on the frequency but can cause more or less pulses per gallon).

I may be wrong, but from your pictures it looks like you have the sensor mounted on the engine baffles .... that vibrate with the engine. The vibration may be leading to the deviations you are seeing. Just trying to help.

Bill

Wires go up and there should be at least 12" from any 90 deg bend.

To: Mr. Greg Richter,

Good evening,
I sent you the KX165 and test harness VIA UPS, You'll receive it this Fri. 25th.
Please call when you have it hooked up in the test fixture so we can discuss.

Thank You
Sincerely
Richard Cano

Richard,

Just an observation from someone sitting on the sidelines watching: You have an airplane. Take a week off work, fly down to see Greg. Let him look at your EFIS while it's installed in YOUR airplane vice a test fixture.

Don't you think it would be more productive if you could SHOW him face to face what your issues are? All of this back and forth would seem to me to be a waste of time. In person, you reduce the risk of miscommunication. In the long run it'll probably be cheaper than shipping stuff back and forth and arguing about what is/isn't broke for the next year.

I didn't even see where Greg agreed to hook anything up in a test fixture and check Richard's wiring....if you did, Greg, more power to you.

The EFIS works as advertised....period. Greg has no more responsibility to ensure we hook up radios right than Garmin does to ensure we hook up the EFIS right....why not send Garmin the EFIS harness?

I agree with PJ.....install the thing and get your airplane to TN. Or, get Bob down to Galvaston.....
