Calibration /Unit for slope mV/pH
%
Unit of the slope.
The % display refers to the Nernst slope of
-59.2 mV/pH (100 x determined slope/Nernst
slope).
QSC /First calibration - Starts the initial calibration with QSC buffers.
This menu item is only available as long as
no initial calibration was carried out with the
connected IDS sensor.
QSC /Record of first calibration - Displays the calibration record of the QSC ini-
tial calibration
QSC /Control calibration - Starts the control calibration with QSC buf-
fers.
This menu item is only available if an initial
calibration was carried out with the con-
nected IDS sensor.
Man. temperature -25 ... +25 ...
+130 °C
Entry of the manually determined tempera-
ture
This menu item is only available if an IDS
adapter and is connected.
Alternative temperature on
off
Takes the measured temperature value from
an IDS sensor.
This menu item is only available if an IDS
adapter and an IDS sensor with temperature
sensor are connected.
