Measurement Methods

1,Connect SF6 devices

Connect the threaded end of the measuring pipe to the switch joint, tighten it with a wrench, and close the needle valve at the other end of the measuring pipe; insert one end of the quick connector on the measuring pipe into the air inlet of the instrument; insert one end of the exhaust pipe The exhaust port on the back of the instrument, and put the other end into a trench or window. Finally, connect the switch connector to the SF6 electrical equipment measurement interface and tighten with a wrench;

2,initialization

Turn on the power switch of the instrument, and the instrument will enter the initialization self-calibration process. After the calibration, it will automatically enter the measurement page.

3,Check battery

It is recommended to use DC power first for this instrument. When using DC power, please check the battery power displayed in the upper right corner. If the power indicator turns red, please turn off the phone and charge before continuing to use it.

4,Start measuring

Fully open the flow valve on the front panel of the dew point meter, and then slowly adjust the flow to about 0.5L/M by adjusting the needle valve on the measurement pipe to start measuring the SF6 dew point. The first device takes 5 to 10 minutes to measure, and each subsequent device takes 3 to 5 minutes.

5,Storing data

After the measurement is completed, the data can be saved in the instrument and press the "OK" key to bring up the operation menu. See the next section for specific operation methods.

6,Measure other equipment

After the measurement of a piece of equipment is completed, close the needle valve on the measuring pipe. Remove the switch connector together with the measuring pipe from the SF6 electrical device. If you need to continue measuring other devices, please do not turn off the instrument power and follow the steps above to continue measuring the next device.

7,Measurement ended

After all equipment measurements are completed, turn off the instrument power.
