Conductivity meter operation steps

Posted on


When the conductivity meter does not turn on the power switch, observe whether the hands indicate zero. If the screws on the meter can be adjusted, make the hands indicate zero.

 

Set the correction measurement switch to the "Calibration" position.

 

 

Turn on the conductivity meter power switch and let it warm up for a few minutes until the pointer is fully stabilized. Adjust the “adjustment” regulator so that the meter indicates fullness.

 

When using the (1)-(8) range to measure liquids with conductivity below 300, select “Low Week”, then turn the high/low switch to low. When using the (9)-(10) range to measure a liquid with a conductivity in the range of 300 to 1051, it will be pulled to the "high cycle."

 

Switch the conductivity meter range selection switch to the desired measurement range. If you do not know the conductivity of the measured solution in advance, you should first push it to the maximum measurement file, and then gradually decrease to prevent the hands from bending.

 

Use of the electrode: When the conductivity meter is used, clamp the electrode bakelite cap with the electrode clamp and fix the electrode clamp on the electrode rod.

(1) When the conductivity of the test solution is lower than 0.3 using a DJS-0.1 electrode, then the "electrode constant compensation regulator" should be adjusted to 10 times the supporting electrode constant: For example, the matching electrode constant is 0.090 , it should be adjusted to 0.90 position.

(2) When the conductivity of the tested solution is lower than 10, use the DJS-0.1 type electrode. At this time, the “electrode constant compensation adjuster” should be adjusted to the corresponding position of the electrode constant: for example, the matching electrode constant is 0.95. , it should be adjusted to 0.95 position, and if the matching electrode constant is 1.1, it should be adjusted in the 1.1 position.

 

Insert the electrode plug into the electrode socket, tighten the fastening screw on the socket, and plunge the electrode into the solution to be tested.
