Display Action Remark
Stability check:
The measured mV value is
displayed.
To abort stability
check: Press cal.
(accuracy reduced)
Calibration with the first buffer
is terminated. Remove the
electrode and temp probe
from the first buffer solution
and rinse them thoroughly.
• One-point calibration:
Press cal to end the calibration.
Slope [%] and offset [mV] of
the electrode are displayed.
Press enter to proceed.
For one-point
calibration only:
• Two-point calibration:
Immerse sensor and tempera-
ture probe in the second buffer
solution.
Press enter to start.
The calibration pro-
cess runs again as
for the first buffer.
Retract electrode and temp
probe out of second buffer,
rinse off, re-install.
Repeat calibration: cal
End calibration: enter
Slope and offset of
electrode (related to
25 °C) are displayed.
pH value and “Hold” are
displayed alternately. Sensoface
is active, “enter” blinks.
Press enter to proceed.
Hold is deactivated after 20 sec.
Confirmation
prompt.
