Calibration of Standard Solution
The sensor has been factory calibrated before delivery and users can use it directly.
Note: Calibration if required can be made using at least one of the five calibration points. Not all points are
required for sensor calibration
If calibration is required, prepare a suitable standard reference liquid with known range value. Press the
[MENU] button to enter the
Setting Mode — select the calibration point.
Enter the corresponding reference calibration value, then press
[ENT] key to confirm and enter the calibration screen.
(If the instrument has been calibrated, the screen shows the calibration status. press the
key to switch the calibration state of the
calibration point. If re-calibration is required in this mode, press the
[ENT] key again to enter the re-calibration.)
In the standard solution calibration mode, press the
key to switch the calibration points, press the
[ENT] key to start calibrating.
If prompted to enter the calibration security password, press the
key or
key to set the calibration security password, and
then press the
[ENT] key to confirm the calibration security password.
