3.14.6 Custom calibration buffers
You can define five of your own calibration buffers which can then be
used for calibration with automatic buffer recognition. The buffer
series can be selected in the CAL (calibration) command as the Custom
buffer series (see Section 4.7).
Open the dialog Templates/Custom calibration buffers.
Enter the pH of the first buffer under Buffer 1.
Use Temp.table to open the temperature table for this buffer. The
temperature table shows the pH values for the buffer at
temperatures from 0 to 95 °C.
Use [Edit pH value] to enter the pH values for the temperature
range in which you perform your pH calibration and pH
measurement. In the dialog [Temperature table/Edit pH value]
you can change directly to the next temperature. If you do not know
the pH values for individual temperatures, these will be calculated
automatically by linear interpolation.
