Chapter 4 System menu
4.1 Mode
pH mode
Through mode option, pH mode can be selected. The main display numbers and
units of the measurement display interface will be switched to pH value and its
unit pH, and other parameters in the configuration settings will also be switched to
parameters in pH mode.
ORP mode
Through mode option, ORP mode can be selected. The main display number and
unit of the measurement display interface will be switched to the ORP value and
its unit mV, and other parameters in the configuration settings will also be
switched to the parameters in ORP mode.
Antimony mode
Through mode option, antimony mode can be selected, which only support the
measurement of antimony electrode. The main display numbers and units of the
measurement display interface will be switched to the antimony electrode
measurement value and its unit pH. Other parameters in the configuration settings
will also be switched to the parameter in antimony mode.
4.2 Calibration
pH calibration
When it is pH mode, the pH calibration function can be used. The calibration
points can be selected from 1 to 3 points. The specific calibration steps are as
follows:
pH 1-point calibration: Select 1 point for calibration point, press [ENT] to
enter the pH 1-point calibration interface, change the standard value on
the interface to the theoretical value of the current pH standard buffer
