pH Measuring Module
The 2-point calibration can be started with the start calibration function.
The go on function terminates the calibration and opens the calibration module
selection menu.
Buffer temperature
This is where the buffer temperature of the reference solution is set.
This is required to enable automatic measured-value temperature compensation.
Value range: 0 to 99 °C (Fahrenheit: 32 °F to 212 °F)
Rinsing with buffer
solution 1
The measuring probe must now be immersed in the buffer solution with the pH value
specified for the first reference measurement. Once this has been ensured the
calibration can be continued through operating ENTER.
Measurement 1
This is where the mV-signal of the reference buffer solution is automatically measured.
The indication of the measurement voltage makes it easier to estimate the
measurement's duration. If the measured value does not change anymore, it can be
assumed that the measurement will be completed shortly and that the calibration will
continue automatically.
The calibration process can be cancelled through operating ENTER.
Rinsing with buffer
solution 2
The measurement probe must now be immersed in the buffer solution with the pH
value specified for the second reference measurement. Once this has been ensured
the calibration can be continued through operating ENTER.
