Q: What kind of appliances are these? What role does it play? Not how the measured current clamp meter?: 1: monolithic leakage protection, K pass, 2: monolithic current protection, K shutdown, 3: three piece, three-phase current protection, K switch1_ automatic unloading gate leakage phenomenon2_ working current exceeds the rated current automatic unloading gate3_ 1: three-phase current balance automatic discharge gate 2: three-phase current exceeds the rated current automatic unloading gateThe clamp type table. Q: according to your figure _ device must AC clamp meter a! [safety test: three-phase A, B, C working current]Recommendations: 1 and 2 switch _ replaced two into two: Ayumi with good performance 'protector'!!

Q: Air conditioning suddenly does not cool down, what's the matter?: Air conditioning is not one of the reasons for refrigeration: Freon is not enough (commonly known as lack of snow) solution: add freon, that can solve the problem of air conditioning is not refrigeration.

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 measure the current limiting resistor of electrostatic ring?: Measurement of grounding resistance can not use a multimeter, because the meter does not have the accuracy of this requirement, grounding resistance instrument at least 0.01 euro readings,

Q: Why is double speed motor low speed r current and high speed current?: 1) the supply voltage is the same, when the output power is certain, the current of the low speed motor must be large;2) the supply voltage is the same, the output torque must be certain, the high speed of the motor is certainly high;

Q: Measurement of AC and DC dual-use electrical instruments, overload ability of the instrument for?: This is the moving coil instrument, which means the electronic device, do not make a mistake.

Q: The reason that the phase current meter of the three-phase asynchronous motor is too low and the other two phases is normal is that it is too normal: If it is a new repair motor, and the three-phase voltage balance is the current is too low, there is a problem with the phase turns and wire diameter, two is the current meter and transformer problems.

Q: How to use the multimeter to check the grounding wire is normal?: It is easy to detect by the clamp type meter, without the ground wire being disengaged, but the actual test is impedance. If the earth wire has current, the error of detection will be greater.

Q: The power consumption of the same load, different power motors?: The current may be a little smaller, because the power consumption of the motor will be smaller in every respect. Both active and reactive power will be smaller.

Q: Use clamp ammeters, wire requirements will be placed in the window center. Why is this?: The measured voltage clamp meter shall not exceed the values marked on the ground, otherwise easy to cause the accident, or cause the risk of electric shock.
