Calibration
For example, to compensate for interfering influences by external
ions, you can carry out a calibration with a standard solution or with
sample water. The correction factor is calculated automatically after
measurement by the Testomat
®
EVO TH CAL. You can also use a
laboratory analysis to determine the correction factor and enter it in
the device.
Using the calibration function
If data is incorrectly entered or the calibration is incorrectly carried
out with the standard solution, you will get incorrect readings!
Enter the correction factor in the range from 0.50 to 1.50
Take a current measurement and note the measured value
Take a water sample at the same time and check the measured
value with a higher value method
From the two values, determine the correction factor (laboratory
value divided by the Testomat
®
EVO TH CAL measured value)
Then select from menu => BASIC PROGRAM => CALIBRA-
TION
Select the menu item “FACTOR“
