1.1 pH Sensor Calibration
Calibration Menu pH Sensor
Before immersion, rinse the electrode in clean tap water.
TEC buffer
Technical buffer solution
∗
LAB buffer
Laboratory buffer solution / Calibration according to NIST/DIN
Temp. compensated
The temperature compensation is automatic,
if a temperature sensor exists.
Temp. manual
The temperature compensation is carried out man-
ual,
i.e. the temperature is entered from a menu.
Aborts calibration, switches to Calibration menu pH sensor.
Saves the entry and switches to the next menu.
Before immersion, rinse the electrode in clean tap water.
At the right border of the last menu
there is a quality factor graphically displayed.
Calculated from offset and slope.
If during the calibration procedure the permissible range of values has been exceeded, this is displayed with
inf
or
-inf
. If undefined values were entered during the calibration procedure, this is displayed with
nan
.
