Adjusting principle:
0%AD is used to adjust for dry condition reading inconsistency.
When the displayed moisture readings are too high at dry soil
condition, you could lower the slope rate by increasing the 0%AD
value.
100%AD is used to adapt for wet condition reading inconsistency.
When the displayed moisture readings are too low at extremely wet
soil condition, you could decrease the 100%AD value to fix it.
Please refer to the below example for better understanding.
For example:
When you use this product at the first time, please turn off the custom
mode and test the product at the following two situations:
Situation One:
You watered your potted plant with enough water and the soil should
be extremely wet, however the displayed moisture readings is much
lower than 95%(e.g.70%).
Solution:
Enable custom mode, and enter 100%AD setting mode.
Hold the ADD+ button, till the 100%AD value reaches 1000 and roll
over back to 80 ( if your 0%AD is 70 and not changed). Now the
100%AD value will start from 80 while the displayed moisture readings
will be calculated to be 100%.
Hold the ADD+ button till the moisture readings start to decrease until
it shows 95%.
Record the 100%AD value for future use (when batteries changed).
Situation Two:
