I have added the cerbo gx and have waited for the custom setting to be added for the ohms setting for tank senders but my senders are outside the custom limits, mine are 10-300 ohms.
Can the limits be increased??
What you can do is to add a resistor paralell to the tank sensor.
In the case of @rob-roy he has 371.3 ohm by 90%.
That makes 412,5 ohm at 100% from his tank sensor at max.
To get a max of the Cerbo GX needed 300 ohm you can add a 1100 ohm (1.1K) resistor paralell to your cable connection inside thehousing of the tank sensor or at the tank input of the Cerbo GX.
Try it: it has workedon may VAN's
