Common abnormal display instructions:

Display [OL.] means the data exceeds the range (overload)
Display [NC.] means the probe is not connected or the signal is disconnected (no connect)
The display [ATC] indicates that the temperature effect on the pH value is compensated (auto temperature compansation). The
acidity and alkalinity of the solution will be affected by temperature changes. If the acidity and alkalinity of the solution to
be tested are not affected by temperature, you can short-press the ENTER key to cancel the ATC compensation.
