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

solution, and then put the pH electrode into the pH standard buffer solution.
After the actual measurement value is stable, press [ENT] to confirm the
calibration and return to the menu interface.
pH 2-point calibration: Select 2 points for calibration point and press [ENT]
to enter the calibration point selection interface. You can choose from 6
types of calibration point combinations: 4.00 / 6.86, 6.86 / 9.18, 4.00 / 9.18,
4.01 / 7.00, 7.00 / 10.01, 4.01 / 10.01. Press [ENT] to confirm the selected
calibration point and enter the first point interface of pH 2-point calibration.
Put the pH electrode into the first pH standard buffer solution. After the
actual measurement value is stable, press [ENT] to confirm the calibration
and enter the second point interface of pH 2-point calibration. Put the pH
electrode into the second pH standard buffer solution. After the actual
measurement value is stable, press [ENT] to confirm the calibration and
return to the menu interface.
pH 3-point calibration: Select 3 points for calibration point and press [ENT]
to enter the calibration point selection interface. You can choose from two
types of calibration point combinations: 4.00 / 6.86 / 9.18, 4.01 / 7.00 /
10.01. Press [ENT] to confirm the selected calibration point and enter the
first point interface of pH 3-point calibration. Put the pH electrode into the
first pH standard buffer solution. After the actual measurement value is
stable, press the [ENT] to confirm the calibration and enter the second
point interface of pH 3-point calibration. Put the pH electrode into the
second pH standard buffer solution. After the actual measurement value is
stable, press the [ENT] to confirm the calibration and enter the third point
interface of pH 3-point calibration. After the actual measurement value is
stable, press [ENT] to confirm the calibration and return to the menu
interface.

ORP calibration
When it is ORP mode, the ORP calibration function can be used. The calibration
points can be selected from 1 to 2 points. The specific calibration steps are as
follows:
ORP 1-point calibration: Select 1 point for calibration point, press [ENT] to
enter the ORP 1-point calibration interface, change the standard value on
the interface to the theoretical value of the current ORP standard buffer
solution, and then put the ORP electrode into the ORP standard buffer
solution. After the actual measurement value is stable, press [ENT] to
confirm the calibration and return to the menu interface.
ORP 2 point calibration: Select 2 points for calibration point, press [ENT]
to enter the first point interface of the ORP 2 point calibration, change the
standard value on the interface to the current theoretical value of the first
ORP standard buffer solution, and then put the ORP electrode into the first
ORP standard buffer solution. After the actual measurement value is stable,
press [ENT] to confirm the calibration and enter the second point interface
of ORP 2-point calibration. Change the standard value on the interface to
the current theoretical value of the second ORP standard buffer solution,
and then put the ORP electrode into the second ORP standard buffer
solution. After the actual measurement value is stable, press the [ENT] key
to confirm the calibration and return to the menu interface.
Antimony calibration
When it is antimony mode, antimony calibration function can be used. The
calibration point can be selected from 1 to 3 points. The specific calibration steps
are the same as those of pH calibration. An antimony electrode is required for
measurement.
