pH calibration "Calibration with manual buffer"
"Calibration with buffer table" /
"Calibration with automatic buffer recognition"
Manual buffer : The buffer pH value is entered manually. The display then shows the current
measured value.
Buffer table : In the calibration menu from page 67 onwards, you can set two buffer solutions or
define them yourself. The selected pH value and buffer type are displayed.
Automatic buffer recognition : The device automatically recognises the used buffer. Select the buffer
types (e.g. E+H) in the Calibration menu.
