6
Temperature correction in units of 0.1 Increase or decrease by 0.1
7
Brix corresponding to the lower limit 4mA
in the current 4-20mA Default 0%
8
Temperature 4-20mA upper limit 1 as the unit
Increase or decrease the upper limit of the solution 4-20mA output
by 1. When the temperature value is greater than or equal to the
upper limit, the output is 20mA, and the value range is -10-130
9
Temperature 4-20mA lower limit 1 as the unit Increment or decrement the lower limit of the 4-20mA output of the
solution by 1, when the temperature value ≥the upper limit, the
output 4mA, the value range is -10-130
