pH & mV MODE
7.1.2 pH Menu
Options from this screen (except the Resolution option) refer to the pH electrode calibration
functions.
7.1.2.1 Add a Buffer (Auto-Entry)
Add a new buffer (up to 5 buffers can be added) or replace an existing one from the
electrode standardization table. The buffer is now automatically recognized and temperature
compensated from the created buffer list (see section 7.1.2.4 Edit Buffer Set).
The titrator accepts electrode’s slope between 80 to 105%.
7.1.2.2 Add a Buffer (Manual-Entry)
The user can add a custom buffer to the calibration list. The titrator will prompt for the
custom buffer value. The buffer value entered should be correlated with the expected
temperature value. The range is from –2.000 to 20.000 pH.
The titrator accepts electrode’s slope between 80 to 105%.
