6.3 Temperature settings

1. Set MTC temperature
If the meter does not detect a temperature probe, MTC appears on the display. In this case the sam-
ple temperature should be entered manually. An MTC value between -30 °C and 130 °C can be en-
tered.
2. Temperature unit
Select the temperature unit: °C or °F. The temperature value is automatically converted between the
two units.
6.4 pH/ion calibration settings
1. Buffer groups/standards
1. Predefined pH buffer groups
One of seven predefined buffer groups can be selected:
B1
B2
B3
B4
B5
B6
B7
Temperature tables for these buffers are programmed in the meter and can be found in the "Appendix".
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
tem per a ture difference between pH buffers must be at least 5 °C and the difference between the pH val-
ues must be at least 1.
When switching from predefined buffer group to customized buffer group, press Save in the table even if
no values have changed.
