Hi I have 2 sensors and both read incorrectly. i put both ends into a bucket of water. 1 reads 50% other reads 75% both should red 100%. is there a way to calibrate them.

Update after 2 hrs both reading almost 100%. Do they self calibrate ?

thanks

Due to external factors on our property it would be very useful to be able to set the current moisture level for a zone. Is there a way to do this ?
