Keypad
Pressing
turns the pH meter on or
switches to standby mode. Standby mode is indi-
cated by a lighted Sensoface
®
status display or two
measurement symbols. At power-on, the pH meter
automatically performs a short self test and then
goes to measuring mode.
Pressing
opens the Calibration level. On the
Calibration level the pH meter is adapted to the
electrode. You can conduct either a one or a two-
point calibration.
Pressing
opens the Parameter level. On the
Parameter level all variable device parameters are
set.
• In the VIEW menu you can view all parameters.

ters.
Pressing
opens the Diagnostics level. On the
Diagnostics level you can get information on the
electrode condition, view the current electrode
data, and perform a complete device self test.
• The Sensoface
®
menu lists the individual param-
eters of Sensoface
®
automatic electrode monitor-
ing with the corresponding evaluations.
• The Electrode Data menu shows the values for
zero and slope of the electrode determined during
last calibration, the remaining time until the next
due calibration determined by the calibration timer
and the data of the electrode statistics.
• With the Knick Fullcheck
®
menu, a complete
device self-test is performed.
