Calibration point 1: After entering the calibration mode, the current measurement value will be displayed. This is known as the standard
solution value.
Place the electrode into the standard solution of the corresponding value, and the corresponding voltage mV value and calibration state
will be displayed on the screen.
After completion of calibration,
Done
will be displayed on the right side of the screen.
If you want to calibrate the next point, press the
key to switch the calibration point.
If only one point calibration is required, press the
[MENU] key to return to the superior menu after calibration.
During the calibration process, the calibration status will be displayed on the right side of the screen.
Done
indicates successful calibration,
Calibrating
indicates in calibration, and
Error
indicates a sensor or a calibration issue.

Offset adjustment
Compare the data of laboratory or portable instrument with the data of instrument measurement,if there are errors, the error data can be
modified by this function.
Linear adjustment
Linear values after “field calibration” are stored in this item, with factory data of 1.00. The main value of the instrument displays the known
standard liquid value point.
Place the electrode into the standard solution of the corresponding value, and the corresponding voltage mV value and calibration state
will be displayed on the left side of the screen.
After completion of calibration,
Done
will be displayed on the right side of the screen. If the next point is calibrated, press
to switch
the calibration point.
If only one point calibration is needed, after the calibration is completed, press
[MENU] to exit. During the calibration process, when the
standard solution is wrong, the screen will show an
