Interface Description

After the instrument is powered on, the system will start automatically. You can view

the detection data of the sensor through the interface and use other functions through

the touch screen.

⚠When the system starts, the interface will prompt "Press and hold the screen to enter

system configuration". Do not operate. The configuration has been completed at the

factory.

SET

Click "SET" to enter the following page for parameter calibration.

CAL parameter: used to calibrate the sensor.

Cal parameters

Click “CAL parameter” to enter the following page:

Take the "pH" sensor as an example：Click “pH”to enter the following page.

⚠The "Up range", "Down range", "coefficient", "OFFSET" and "Factory geometry values"

have been set at the factory, so please do not modify them.

Curve

Records

Click “Records”to enter to the following page:

Click " Export data" to enter the following page, set the time range for data export, and

click "Export data" to export the data to USB（Excel format）.

The system can save 30000 pieces of historical data. If there are more than 30000

pieces of data, the system will automatically overwrite the earliest data.

Warning

Click “Warning ”to enter the following page:

Insrtuction

Calibration

The sensor has been calibrated before delivery and can be used directly.

⚠It is recommended to calibrate the sensor on or before the day of use.

⚠Calibrate sensor every 30days.

⚠It is recommended to purchase the third party's standard solution for calibration.

pH Sensor

Preparation：deionized water, pH6.86 and pH4.01standard solution.

1. Connect the instrument and PH sensor, and then power on the instrument. Click "SET"

- "Cal Parameters" - "pH" to enter pH sensor calibration page. As shown below:

2. Put the connected and energized pH sensor in pH6.86 standard solution for about 2

minutes, observe the value in the "real-time signal" on the page, and click the "Point1"

button to confirm after the value is stable (value range change is less than ±0.02). As

shown below:

3. Put the pH sensor into deionized water for cleaning, and dry it with clean tissue. Then

put the pH sensor into pH4.01 standard solution for about 2 minutes. Observe the value

in the "Real time signal" on the display page, and click the "Point2" button to complete

the calibration after the value is stable (value range change is less than ±0.02). As

shown below:

4. Put the pH sensor into deionized water for cleaning, and then dry it with tissue , and

then put it into 3 mmol/l potassium chloride solution for storage.

Turbidity Sensor

Preparation：deionized water, 0NTU and 10NTU standard solution.

⚠Turbidity sensor is an optical sensor. Please use a light proof container during

calibration.

1. Connect the instrument and turbidity sensor, and then power on the instrument. Click

"SET" - "Cal Parameters" - "TUR" to enter turbidity sensor calibration page. As shown

below:

2. Put the connected and energized turbidity sensor in 0NTU standard solution for about

5 minutes, observe the value in the "real-time signal" on the page, and click the "Piont1"

button to confirm after the value is stable (value range change is within ± 5%). As shown

below:

3. Put the turbidity sensor into deionized water for cleaning, and dry it with clean tissue.

Then put the turbidity sensor into 10NTU standard solution for about 5 minutes.

Observe the value in the "Real time signal" on the display page, and click the "Piont2"

button to complete the calibration after the value is stable (value range change is within

± 5%). As shown below:

4. Put the turbidity sensor into deionized water for cleaning, and then dry it with tissue ,

and then store it.

Ammonia Nitrogen Sensor

Preparation：deionized water, 1.000ppm and 10.000ppm standard solution.

1. Connect the instrument and ammonia nitrogen sensor, and then power on the

instrument. Click"SET" - "Cal Parameters"- " NH3-N " to enter ammonia nitrogen sensor

calibration page. As shown below:

2. Put the connected and energized ammonia nitrogen sensor in 1.000ppm standard

solution for about 3 minutes, observe the value in the "real-time signal" on the page, and

click the "Point1" button to confirm after the value is stable (value range change is less

than ±0.03). As shown below:
