Q: DC screen operation of the display voltage imbalance, what reason, divided into operation, reported: There is a ground fault in the switch or cable or switch. Check the ground.

Q: Why is the air compressor leakage gap will open?: Your fault may be indoor and outdoor connection line problems, the best method of inspection is to check the section to determine, otherwise you can check out the problem!

Q: A selection table clamp type table: Because the clamp table itself is of low precision, small current measurement, can adopt the following methods: first, the measured circuit of the wire around a few times, were measured and then put into the jaw in clamp meter. The current clamp meter indicating the value of the actual value is not measured, the actual current should be divided by the wire clamp meter readings for winding the coil number.

Q: How to use the correct measuring clamp current meter: 1, in the high pressure loop measurement, prohibit the use of lead from the clamp ammeters another meter measurement. When measuring the phase current of high voltage cable, the distance between the cable head and line should be above 300mm, and the insulation is good, which can be carried out when the measurement is convenient. 2, the observation time, we must pay special attention to keep a safe distance from the head and charged part of the human body and any part of the charged body distance shall not be less than the entire length of the clamp meter. 3. When measuring low voltage fusible fuse or horizontally arranged low voltage bus current, each phase shall be protected or insulated by insulation materials, so as to avoid interphase short circuit4, the use of high voltage clamp current meter should be paid attention to when the voltage clamp current meter, prohibit the use of low voltage electric current clamp meter high voltage measurement circuit. With high voltage clamp meter measurement, by the two person operation, non duty measurement should fill in second working ticket, should wear gloves when measuring stand on the insulating mat, must not touch the other equipment, to prevent a short circuit or grounding.5, after the end of the clamp current meter to measure the switch to the maximum file, so that next time use careless flow; and should be kept in a dry room6, when the cable has a ground, it is strictly prohibited to measure. To prevent the breakdown of the ground due to the low insulation level of the cable head, and endanger personal safety.7, clamp meter measurement, near the wire current, also have influence on it, so must pay attention to the position of the wire to the equal phase.8, maintenance should not live operation, in case of electric shock.

Q: How to maintain and maintain the communication and power room?: AC / DC clamp type meter. AC / DC clamp meter as the daily maintenance work is one of the essential test tool, mainly used to test the voltage, current, frequency and other related parameters, it has high resolution and precision testing and more testing function. At present, the maintenance personnel usually use the FLUKE of the United States F337 AC / DC Clamp Meter (RMS), and Silicon Valley communication production of SGT-11A and SGT-12B single and double jaw clamp type table, this kind of instrument with large diameter and small jaw electrical test resolution and high precision, accurate measurement, current flow the characteristics of. At the same time, the manual design of this kind of pliers is very suitable for the occasions with small space. Noise meter. The noise meter is mainly used to test the pulse component of rectifier equipment and DC converter output voltage, that is, noise voltage. At present, the noise meter in the market is mainly analog and digital. The analog noise meter is mainly JH5151 of state owned Jianhua instrument factory. Although it is larger and heavier, it has many testing indexes and high accuracy. Digital noise meter mainly has FZY-120 and FZY-120A, it has light and easy, portable, simple test, visual display and so on. At present, maintenance personnel can choose to use according to their favorite.

Q: What is the current clamp? What are the main points on ammeter selection?: Simple operation, do not need to test large current circuit can be directly connected. Safety clamp meter, multimeter and insulation resistance meter are analogue and digital two. The detection range of the standard type: AC, DC from 2A to 200A or 400A, also can be detected by 2000A high current products leakage detection; micro current detection and product number mA and the detection of transformer power supply

Q: How to test the current on a motor?: Oscilloscope sensitivity is very high, there are tens of MV signal can be stable observation, if elected 5A out of 100mVThere are: 0.1V/5A=0.02 europe.For such a small resistance, the motor running state has little influence, if there is no instrument to do the measurement, you can take the current voltage method,Is to use a section of wire, through the 5A, and then measured the voltage =100mV at both ends of the wire, do not meet the change of wire length.

Q: But after 3 minutes on the machine, there is no electricity, what's the matter?: If you can't open the circuit check all the best hit the table of capacitance, resistance to clamp type table file, two probe and two terminal capacitor contact, began to pass, slowly not normal. The frequent capacitance of the switch is easily damaged by current. If there is no problem, it may be where the leakage of fluoride, or Freon is not enough. If the system does not leak, the difference is only fluoride, that is, fluoride will be OK, if the leak, then a little trouble

Q: What is the connection between the distribution box and the bridge?: The ground wire is at least 4 square cord, 4 square wire rated operating current of about 30A, since it has been burned, indicating that the current has doubled, and the current duration is longer.

Q: How to use the caliper and its working principle?: A multimeter is a very common electrical appliance, the clamp clamp, only for the exchange of test.
