The reference temperature is set in the Temperature Compensation menu (default: 25.0°C).
Input temperatures for compensation in the Temp. ranges menu.
Input values from Solution 1 (low pH) to Solution 5 (high pH).
After entering all values, select “Check values?” to verify that there is no error. This function
