Reef Angel Forum

I'm trying to calibrate the water level sensor and it's not showing any readings under the calibrations

The reading show a zero in red and when I press ok the reading on the left goes to 100%. Could the cable or sensor be bad which I don't think so because I just got the sensor today. It seems that the reef angel is not reading that is connected I assume due to not showing any readings

You start at the screen where it shows 0. You put the sensor in a bottle or bucket of water that is as deep as you want the 0% mark to be. You click on OK. Then it goes to the 100% screen. Then you fill the bottle to where you want the 100% mark to be on the pipe. Then you click ok and you can put the pipe in the sump where you want it. Now wherever % that you run your sump at you should be able to read the % that it's at. You use that % with the +/- you want to maintain with your ATO into the water level function. Then for the safeties, you can do this.

if (ReefAngel.WaterLevel.GetLevel() > 60 || ReefAngel.WaterLevel.GetLevel() < 40) ReefAngel.Relay.Off(PortX); // Where X is the port number you want to shutoff.

You would change the 40 and 60 to be the levels where you cut it off.

Ok I did that and still no reading on the right side. It shows 0 in red for both.

Ok could it be that the USB port is bad ok my relay box since I never used it or could it be malfunctioning. I'm just not getting any type of reading at all.

Now that you mentioned this, could it be that you are missing some jumpers on the head unit?
Older head units did not come with jumpers pre-installed.
Can you open the head unit and you should see a set of 3 jumpers. All three should be there. If you have only 1, you must set the other 2.

Thanks Roberto that fixed the problem.
