Looking at diagnostics on Fleck 5810SXT... quirk

[Reach4]

To get to the diagnostics mode, the manual says

Diagnostics View Steps
1. Press the Up and Extra Cycle buttons for five seconds while
in service.​

When I do that, the first time I momentarily see "FR 0.0" (flow rate zero). I release the buttons, and it leaves diagnostic mode. I try again, and succeed.

I used to think the failure to enter the mode was because I was not releasing the buttons simultaneously enough, or when it worked it was because I released one of the buttons a few milliseconds before the other. So I would experiment.

I now think it is just that the first one never takes, and the second one will succeed. It's not a big deal, now that I have figured out that it is not my finger release method causing the failure.

My SV (software version) is 3.0 if that matters.

Do others have this quirk?

Try releasing the extra cycle button first. Very deliberately first, like a second or more.

I noticed the same thing on mine when I tried to release the buttons together and figured I was accidentally releasing the up arrow first which would leave you pressing the extra cycle button, which exits the diagnostics screen.

I tried it, and it worked the first time. I had not left sufficient time apparently.

Yet it always seemed to work on the second try. This was the first time for the first try. I probably left 500 ms between releases -- much longer than I had been doing.

I will try again after the unit has not had buttons pressed for a few days.
