key is pressed:
Data entry : Entry of zero point and sensor slope.
Buffer manual : During calibration, enter the buffer
value.
Fixed buffer : If the same buffer values are always
used, you can select this function.
Auto. buffer recognition : The transmitter TopCal S
automatically recognises the used buffer values.

The automatic buffer recognition only functions if glass
electrodes are connected to both measuring circuits.
In case you are using an IsFET sensor, please cali-
