pH & mV MODE
7.1.2.3 Clear Standardization
Deletes electrode standardization. The titrator will prompt for confirmation.
7.1.2.4 Edit Buffer Set
Creates a unique, auto-recognized buffer set. The new calibration standard buffer will be
checked from the set described below.
Available buffers include:
Hanna:
4.01, 6.86, 7.01, 9.18, 10.01
CRC:
1.68, 3.56, 4.01, 6.87, 7.41, 9.18, 12.46
DIN:
1.09, 3.06, 4.65, 6.79, 9.23, 12.75
NIST:
4.01, 6.86, 7.42
To select a buffer from the list, highlight the desired buffer and press
to add it to the
buffer set. The selected buffers are marked with an asterisk.
Note: Although any combination of buffers may be selected, their values should be at least
1.5 pH units apart.
