Set MTC temperature
If the meter does not detect a temperature probe, MTC appears on the display. In this case the sample
temperature should be entered manually. An MTC value between -30 °C and 130 °C can be entered.
Temperature unit
Select the temperature unit: °C or °F. The temperature value is automatically converted between the two
units.

6.4.1 Buffer groups / Standards
6.4.1.1 Predefined pH buffer groups
One of seven predefined buffer groups can be selected:
1.68
B1
2.00
B2
B3
2.00
B4
1.679
B5
1.680
B6
1.09
B7
1.680
Temperature tables for these buffers are programmed in the meter and can be found in the "Appendix".
6.4.1.2 Customized pH buffer group
A set of user-defined pH buffers with up to 5 different temperatures for each buffer can be created. The
temperature difference between pH buffers must be at least 5 °C and the difference between the pH values must
be at least 1.
