Choose the key of “data output” and press the key of “Enter”. After about one minute, connect the
computer when you get the information of “OK”, and make the hand manipulator connect with computer
by USB data wire. Then, a file of 500M will come out in the computer, and save the documents in the file
to the specific location of the computer.
Chapter 6 Calibration of Sensors
The probe is calibrated at the factory and is selectively calibrated depending on the situation on the site.
There is a need to calibrate the sensor when the following situation occurs:
1.
When the measured value of the parameter is inconsistent with the known calibration standard value.
2.
When dirt appears or could be seen obviously.
3.
When the components are replaced.
Some system components are susceptible to time, use, and environment. To ensure the accuracy of the
instrument, it is recommended to perform routine testing under the standard conditions for the system.
Note: If there is only one parameter to be measured, you need not take down other sensors.
6.1 Calibrate the sensor with software
6.1.1 Basic calibration process
1.
Rinse the used probe with clean tap water.
2.
Rinse the calibration container thoroughly with water first and then rinse with a small amount of
standard solution for calibration.
3.
Pour off the rinsed standard solution and refill the calibration container with the unused standard
solution to ensure the sensor is submerged.
Important Tip:
When changing the calibration solution, rinse the calibration container with distilled
water. Please avoid cross-contamination between different standard solutions.
4.
Place the clean and dry probe in the calibration container. It is recommended to use one calibration
container for calibration only and the other hollow calibration container for on-site measurement. By this
