Operation steps

1. Start up and warm up for ten minutes. This process can eliminate the influence of ambient temperature on the test results.

2. Connecting SF6 equipment

a) Connect the threaded end of the measuring pipe with the switch connector and tighten it with a wrench;

b) Then insert one end of the quick connector on the test pipe into the sampling port on the purity instrument - < gas="" inlet="">;

c) Connect the exhaust pipe to the air outlet - < gas="" outlet="">.

3. Check the power

When using DC power, please check the battery power displayed in the upper right corner. If the power is less than about 20%, please turn off and continue to use after charging.

4. Start measurement

First, open the meter to measure the needle valve on the pipe, then adjust the flow valve on the panel of the purity tester, adjust the flow to about 0.5L/M, and start measuring the purity value of the SF6 gas.

5. Store data

After the equipment measurement is completed, the data can be saved in the instrument, and press the "data query" key to call out the operation menu.

6. Measuring other equipment

After one equipment is measured, close the needle valve on the measuring pipeline and the regulating valve on the purity instrument. Remove the adapter from the SF6 Electrical equipment. If it is necessary to continue to measure other equipment, continue to measure the next equipment according to the above steps.

7. End of measurement

After the measurement of all equipment, turn off the power supply of the purity instrument.
