I have a newly assembled Eggtimer Quantum that is acting strange. I am wondering if anyone else has seen anything similar. The unit powers up, and all the screens are OK. ( Main, Setup, Testing ) I did tested the output channels with Estes Igniters, and they fired fine. I would say all is good to go.... BUT the issue I noticed was that the ASL Altitude displayed on the main screen seems to jump around with each refresh of the screen. I am used to seeing a VERY small change with each refresh of the page... but not this much.
I decided to make test of it from a cold start a few hours later. Below is data taken from the main screen over 15min period. Each time it would beep and refresh, I wrote down the ASL, Volts, and Temp...
Reading ASL Volt Temp
1 1089 7.4 72.0
2 1011 7.4 69.6
3 997 7.4 69.3
4 1016 7.4 69.8
5 1040 7.4 69.8
6 992 7.4 70.3
7 989 7.4 70.3
8 1055 7.4 70.9
9 1009 7.4 72.0
10 1025 7.4 72.2
11 1006 7.4 62.2
12 961 7.4 62.2
13 998 7.3 62.1
14 972 7.4 62.1
15 1013 7.3 61.7
Max = 1089' / Min = 961' / Difference = 128' while sitting on my desk next to the Proton.
Since the Quantum readings seemed odd. I fired up a Proton and recorded the same data. It is MUCH more stable in the ASL reading.

15 993 7.7 69.4
Max = 996' / Min = 993' / Difference = 3' while sitting on my desk next to the Quantum.
Both of these are from "Cold Start". Not sure what to do, but I don't think I can trust the Quantum....
@cerving Any thoughts.
