D. Setup and Calibrate the Electrode and Meter
VisionPlus EC 330 must be setup and calibrated before your
first use. Please follow the instructions detailed in section
USING VISIONPLUS EC 330 6
.
USING VISIONPLUS EC 330
A. Power On/Off
Press the “On/Off ” key to turn the unit on. If the unit is running
then you can press the ”On/Off “ key to turn the unit off. The unit
will automatically turn off after 10 minutes of no key activity.
[
Note:
The unit will not automatically shut off if it is still immersed
in solution even after 10 minute of no key activity.]
B. Calibrate Conductivity
The user can select one or two point conductivity calibration.
1. Rinse the electrode & ATC assembly in distilled water and
immerse them in the standard solution of 1413uS. The
temperature displayed is the solution temperature.
2. Press “Cal” key to initiate calibration. The “CAL” icon will
appear when the main display shows “1415”.
Single
Point
calibration is now complete. The “MEAS” icon will
appear. The unit is now ready to measure.
[
Note:
At this moment, the unit can measure 0~2000uS
range of conductivity.]
3. Remove the electrode & ATC assembly from the standard
solution of 1413uS. Rinse them in distilled water and
immerse them in the standard solution of 12.90mS. The
unit will display the temperature of the standard solution
of 12.90mS.
4. Press “Cal” key to initiate calibration. The “CAL” icon will
appear when the main display shows “12.90”.
Dual
Points
calibration is now complete. The “MEAS” icon will
appear. The unit is now ready to measure.
[
Note:
At this moment, the unit can measure
0.0~20.00mS range of conductivity. ]
