4.7.3 Settings for pH measurements
Overview The following settings are possible for pH measurements:
z Calibration record (display)
z Calibration data storage (display)
z Calibration interval
z Buffers for calibration
z Single-point calibration
z Unit for slope
z Resolution
Settings The settings are made in the menu for calibration and measurement
settings of the pH/ORP measurement. To open the settings, display the
required parameter in the measured value display and press the
<MENU/ENTER> key. After completing the settings, switch to the mea-
sured value display with <M>.
Default settings are printed in bold.
