Tank sending unit/Cerbo GX question

I have installed two tank level sensors on my fresh H2O tanks, plugged them into the Cerbo, powered it back on - and I am unable to enable the Cerbo to "see" the senders. I thought I may have reversed the polarity so it reversed the sender wires and same issue. I have attached photos of the situation for your reference.


Thank you,


Stevo

This is the senders I am using.

Have you tested the senders? Hook a multimeter set to resistance to the sender output. Manually move the sender up and down and check that the resistance fluctuates accordingly.

Yes, they work perfectly.

Thank you for the reply but I found my problem - it was my error. I had the sensor leads connected to the 3 and 4 terminals on the Cerbo GX. When I moved them to the 1 and 2 terminals - all worked as it should. It is very nice to know how much water I have in my holding tanks.
