Standard Solution Calibration
This function is used to calibrate the five calibration points of the sensor. It has been calibrated
before delivery and users can use it directly.
If calibration is required, prepare 5 suitable standard liquids with known range, press the
【
MENU
】
key to enter the setting mode and select the calibration point.
Modify or enter the corresponding calibration value. After setting the calibration value, press
【
ENT
】
key to confirm and enter the calibration screen.
(If the instrument has been calibrated, the screen shows the calibration status. press the
【
Ӝ
】
key to switch the calibration state of the calibration point. If you need re-calibration, in this
state,press the
【
ENT
】
key again to enter the re-calibration.)
Standard solution calibration total has five calibration points,you can choose any one point to
calibration
（
At least,choose one point to calibration).
In the standard solution calibration mode,press the
【
Ӝ
】
key to switch the calibration
points,press the
【
ENT
】
key to start calibrating.
If the monitor prompts you to enter the calibration security password, press the
【▼】
key or
【
Ӝ
】
key to set the calibration security password, and then press the
【
ENT
】
key to confirm the
calibration security password.
Calibration point 1:
Calibration point 1:After entering the calibration mode, the instrument
displays as shown above.
The instrument main measurement value displays the point 1 known 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 left side of 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
【
Ӝ
】
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 failure.
