Remote Monitoring Terminal is a compact device with battery supply, ultra-low power consumption, IP68 protection,
wireless communication and various sensor data collection function,in specific circumstance, multiple power supply options are
available. It is suitable for the monitoring fields without power supply condition and the harsh environment. It could realize the multifunction including data collection, storage, alarming and transmission for underground water, firefighting water, dam water, water
supply and drainage pipeline. Wireless Remote Terminal,Remote Monitoring Terminal,Piping Monitoring Terminal,Remote Telemetry Monitoring Xi'an Gavin Electronic Technology Co., Ltd , https://www.gamicos-meas.com
Second, the characteristics of the instrument fabric friction electric charge tester by Faraday tube, rotary roller friction machine and charge measuring device.
The sample that had been rubbed by the roller friction machine was placed in a Faraday cage to measure the charge of the sample.
Third, the main technical indicators 1, the measurement range: 2nC ~ 2μC, accuracy ± 1%
2. Faraday's canisters all meet the requirements of the 12014-2009 standard. 3. Power supply: AC220V, 50HZ, 50W
Fourth, in line with national standards: GB12014-2009 "anti-static clothing"
V. Operation Step 1 Referring to FIG. 1 , connect the Faraday cup and the charge amount measuring device: connect one end of the dedicated connection line with the input port of the charge amount tester, and connect the other end with the outlet on the outer cylinder of the Faraday cup.
2. Turn on the power of the charge meter - turn the power switch up to the "1" position.
3. Press the "Clear" button to make the charge meter display zero.
4. Use a roller friction machine to rub the sample. Immediately after the friction is completed, use an insulating rod to place the sample in the inner tube of the Faraday cylinder. In this process, the sample and other objects should be maintained more than 300mm.
5. Read the reading on the charge measuring device.
Sixth, pay attention to matters 1, the system's Faraday cylinder tube should be reliably grounded.
2. Please reset the charge measuring device before each measurement.
3, measured objects must be out of power.
4. Before the test, please turn on the power switch to warm up the machine for 15 minutes.
