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,

Field Calibration
When the data from laboratory or portable instrument are input
into this item, the instrument will automatically correct the data.
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.
