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 electrode and
temperature probe in the
second buffer solution. Enter
pH value of second buffer
solution. Press enter to start.
The calibration
process runs again
as for the first buf-
fer.
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. Exit using enter key.
Hold is deactivated after 20 sec.
