Operation
1. Connect To SF6 Electrical Equipment
Connect the screw thread port to the switch joint, screw up it, then close the needle valve on the other head of the tube.
Connect the quick coupling of the test tube to the inlet of the meter.
Connect the vent tube to the outlet.
At last, screw up the switch joint to the SF6 electrical equipment.
2. Initialization
Power on the meter, it will take 5 seconds to initialize.
3. Check The Battery
The meter takes precedence for use alternating current.
when use DC power, view the battery on top right corner. when the battery indicates the electricity less than 20%, please recharge the equipment and then begin to use.
4. Start
Open all needle valves of stream tube, use flow valve adjust flow to about 0.5L/M, then begin to measure the dew point of SF6.
It takes 5-10 minutes for the first measurement, followed test will only need take 3-5 minutes for each device.
5. Save Data
After test,save the data and print it.
6. Test Other Equipment
When complete one set of equipment, close the needle valve of the stream tube and turn off flow valve. Take the adapter off from SF6 electrical equipment. If any equipment needs to be tested repeat steps above.
7. Test Complete
After all tests, Please turn off the equipment.
