About SF6 trace moisture tester operation method and attention

SF6 trace moisture tester operation method
1. First, turn on the power supply and allow the instrument to perform self-calibration (5 minutes before ventilation test).
2. Close the flow regulating valve, connect the intake pipe to the instrument, and connect the other end of the intake pipe to the device.
3. Open the flow control valve and adjust the flow to 0.4 to 0.6L/min.
4. Automatically complete the measurement within a few minutes (for conversion please refer to the data conversion), press the memory key to save the data, press the query key repeatedly to view the historical data.
5. Do not turn off the power of the instrument when it is continuously measured. Repeat the above steps to save the measurement time.
6, the instrument must be used after the closure of the flow control valve, and then turn off the power switch.
Note: If the instrument reacts slowly during the test, close the inlet valve, turn off the instrument and turn it on again to allow the instrument to self-recalibrate, and then open the valve ventilation test after 5 minutes; the data will not change or change within 2 to 3 minutes during the test. Very small, can be considered the end of the test.
The instrument pays attention to the measurement process
1. During the measurement process, when the needle valve is adjusted, it should be opened slowly to prevent abrupt changes in pressure so as to avoid damage to the pressure and flow sensor. The measured gas flow rate should be adjusted to 0.5L/min, which can not only quickly measure, but also save gas;
2. When the instrument is in use, when the battery indicator is not enough, it should be charged in time. When charging, it only needs to connect the power cord to 220V power. It does not need to open the instrument power switch, the instrument is automatically charged, the charging indicator light is on, and the charging indicator is on when charging is completed. Light extinguished
3, the instrument is a precision high-end measuring instrument, should avoid severe vibration;
4, the instrument must be fully charged, do not use for a long time, we must always check whether the power is sufficient;
5, the instrument can not be used to detect corrosive gases, pipelines should be kept dry, can not enter the liquid; when measuring flammable, easy bao gas, you must use direct current! And first boot and then go to the field test; test is completed, leave the scene and then shut down.

Hemp Flour

Hemp flour is a gluten-free flour that does not rise. It is dense and produces a granular texture when used for cooking and baking, much like corn flour. A protein content of approximately 33% makes it very hearty.
High in fibre, fatty acids, vitamins and minerals, hemp flour adds a creative, nutritional twist to home-made bread, muffins, cookies and crepes. With a delicious nutty taste and dark colour, friends and family will be asking you what your secret is!
