Calibration / Calibra-
tion interval
1 ... 7 ...
999 d
Calibration interval for the IDS pH sensor (in days).
The meter reminds you to calibrate regularly by the flashing
sensor symbol in the measuring screen.
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 calibra-
tion was carried out with the connected IDS sensor.
QSC / Record of first
calibration
- Displays the calibration record of the QSC initial calibration.
QSC / Control calibra-
tion
- Starts the control calibration with QSC buffers.
This menu item is only available if an initial calibration was
carried out with the connected IDS sensor.
Man. temperature -25 ... +25
... +130 °C
Entry of the manually determined temperature.
This menu item is only available if an IDS adapter is con-
nected.
