pH measurement
Measuring
"Man" flashes on the screen indicating that the
temperature value can now be entered
manually.
Use the arrow keys to change the value.
Confirm this temperature value with Enter.
The pH value is recalculated.
You can call up the corresponding mV value by
pressing the page key. In this case we are dealing
with the voltage of the pH electrode and not a
redox value.
This value is not temperature compensated.
