4.4.4 Settings for pH and ORP measurements
Overview The following settings are possible for pH and ORP measurements:
z Resolution
z Calibration interval
z Buffers for calibration
z Unit of the temperature
z Automatic stability control
z Unit for slope
z Calibration record (display)
Settings The settings are made in the measuring menu of the pH/ORP
measurement. To open the settings, activate the relevant measuring
window in the measured value display and press the <ENTER> key
shortly
. After completing the settings, switch to the measured value

Calibration interval
1 ... 999 d Calibration interval for the
pH electrode (in days).
The meter reminds you to
calibrate regularly by the
flashing sensor symbol in
the measuring window.
Calibration /Unit for
slope
mV/pH
%
Unit of the slope.
The % display refers to the
Nernst slope of
-59.16 mV/pH (100 x
determined slope/Nernst
slope).
Man. temperature -25 ... +130 °C Entry of the manually
determined temperature.
For measurements without
temperature sensor only.
