– Display in GKL 100 at 25 °C, setpoint = 1413 µS/cm
– Display = 1388 µS/cm
–
S(L
= setpoint / display value
–
S(L
= 1413 µS/cm / 1388 µS/cm = 1.018
NOTE
The most precise results can be achieved when the control solution temperature is ad-
justed to 25 °C. With different temperatures, the table value of the corresponding tem-
perature must be used as a setpoint.
The changed value is saved and the
Configuration
menu is closed.
NOTE
If the product is switched off without saving the configuration, the last save value is re-
produced on the next start-up of the product.
