For sale is a kit to build your own Altitude Encoder Tester.
The kit is $20, or the assembled and working tester in the photos is $120
The $20 price is selling these parts at my cost before the eBay fees I will get. If you purchase these parts separately it would cost much more when you include all the individual shipping cost.
This tester works by lighting up the LED's in a code, (Gillham Code) that you can lookup on a chart, to determine what altitude in feet your encoder is reporting. Next you simply connect vac/pressure tubing to supply your encoder and altimeter with the same air pressure. If your altimeter is set to 29.92 your encoder should report the same elevation, if not you adjust the set screws. go back and forth with high and low elevations adjusting until both are accurate. You will be able to find if your encoder is working correctly at all elevations. You will still need to have your encoder certified before you use it, and again every 2 years.
You connect to your encoder, apply 12 volt power to the black and red wires, wait a few minutes for the encoder to warm up and soon the LED lights will light up in a pattern that when you look up the pattern with the chart you will be able to determine the altitude your encoder is reporting.
Shown in the first photo is a completed working tester and it is not included in this kit, but it is what yours will look like after you assemble it yourself.
Everything you will need to make your own tester is included (minus the wire).
You will need to solder the connections on both the connector and onto the circuit board.
You will also need to drill the holes for the main wiring harness and the 10 LED's into the side of the case.
I will add that this is all very time consuming and that is why I chose not to assemble these before selling them.
If you would like the completed tester that I have shown in the photos then message me when you purchase the kit and send an additional $100 to my PayPal account.
I designed, built, and tested this tester myself and it works perfectly.
I purchased enough parts to build 5 of these testers but after completing the first kit I decided I did not have enough time to assemble the remaining 4 kits so I am simply selling them as kits.
I will include copies of all the documents I used to develop the original tester and hope that it will be enough info for you to complete this kit on your own. I will be available to help you with a few questions you may have but please only purchase this if you feel you are knowledgeable enough to complete this mostly on your own.
I pride myself for fast delivery. I will get your package to the counter of USPS and have them scan it ASAP. You will be able to see your tracking updated to "in USPS possession" right away. I am also Centrally located in the USA and near their major shipping hub.
