1. Connect the SF6 equipment
Connect the thread end of the measuring line with the switch joint, tighten the screw with the wrench, and close the needle valve on the other end of the measuring line.
Insert the quick joint end of the test line into the sampling port on the micro water meter。
Connect the exhaust pipe to the air outlet.
Finally, connect the switch joint to the SF6 electrical equipment measurement interface, and tighten with the wrench;
2. Check the battery
This instrument is recommended to use alternating current。
When using direct current, please check the battery power shown in the upper right corner. If the battery is lower than about 20%, please switch off and use after charging.
3. Start measuring
First all open the instrument to measure the needle valve on the pipe, then use the flow valve on the panel to adjust the flow, adjust the flow rate to about 0。5 L/M, start to measure SF6 dew point。
The first device takes 5 to 10 minutes, and each device takes 3 to 5 minutes。
4. Stored data
After the equipment measurement is completed, the data can be saved in the instrument, and the operation menu can be adjusted by "ok", and the specific operation mode can be seen in the next section.
5. Measure other equipment
After measuring a device, close the needle valve on the gauge line and the regulator on the microwater meter. Remove the adapter from the SF6 electrical equipment. If you need to continue to measure other devices, follow the above steps to continue to measure the next device.
6. End of measurement
After all equipment measurements are completed, close the micro-water instrument source.
