Buffer groups/standards
Predefined pH buffer groups
One of eight predefined buffer groups can be selected:
B1
1.68 4.01
B2 2.00 4.01
B3 2.00 4.00
B4 1.680 4.008
B5
1.09 4.65
B6 1.680 4.003
B7
2.00 4.01
B8 1.679 4.008
Temperature tables for these buffers are programmed in the meter and can be found in the "Appen-
dix".
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.
When switching from predefined buffer group to customized buffer group, press Save in the table
even if no values have changed.
Ion standards
Concentrations for up to 5 standards with one standard temperature can be defined. The ion con-
cen t ra t ion unit for measurements and calibration can be defined. Six concentration units are avail-
able:
●
mmol/L

●
ppm
●
mg/L
●
%
