Q: Why do you use a multimeter to measure the zero line and ground wire?: The normal zero line with ground wire is not the zero line is tapped from the neutral point of transformer, wire from ground tap buried underground, but in actual use, line five wire three-phase voltage is 380 volts, the zero line and ground wire is not feasible, because there is a 220 volt single-phase equipment on the trip, will, 220 volts three-phase five wire circuit, because the zero line is rarely used, so the wiring, the zero line and ground line together.

Q: The difference between digital multimeter and caliper type multimeter: The principle of clamp meter is the use of electromagnetic induction principle, core wire clamp measurement will require the clamp meter of silicon steel lamination edges, then the wire clamp is equivalent to a coil current transformer, belonging to a current through the coil, when will dinner two coil clamp type ammeter inside induction two current, current in the wire clamp type ammeter dial can read the measurements.

Q: According to the three-phase current and voltage, the reactive power and power factor are calculated: The measurement of reactive power requires the difference between the phase of the voltage and the phase of the current. If you measure only the current, or the voltage, it is impossible to come out. While measuring the current, the voltage is measured, the phase of both is sampled, and the phase difference is analyzed by the circuit, then the reactive power or the power factor are calculated. Clamp ammeters a function of such I had not seen.

Q: How to measure current clamp meter: A table is actually a current transformer, the jammed wire is the equivalent of a transformer coil

Q: How to use vc3266l type electric pliers: AC voltage measurement(1 function switch is placed in 600y - file).(2) the black pens are respectively inserted ACOM.V/ jack.(3) with one connected with the detected power or load, when the LCD is reading effective value of AC voltage measurement.

Q: With the operation of the motor current clamp meter measuring three-phase, single-phase current is very low, what is the reason?: Is there a problem with the removal of the caliper?. If you have checked, no problem, you can determine the correct data, low current, or motor without load or light load, or the power of the motor itself is small.

Q: Clamp ammeters on what hold is: The measured current is dynamic, so the digital clamp meter has been beating, press hold, can make the digital positioning in the moment of the current value of the press.

Q: If there is no measurement capacitor on the table, then how to measure the quality of the capacitor?: If the current has been maintaining a value, then the capacitor is breakdown. But if there has been no current, there are two cases, one is the capacitance is too low (PF skin level), another current clamp meter resolution is not enough, in this case, capacitor is unable through current clamp type table to judge.

Q: What's the reason for the leak on the air conditioner? The pipes outside are changed, but the air conditioner is nearby: Central air-conditioning settings are also very important. Hot customers home after open air conditioning, often want to step to set the temperature at 25 DEG C, if the air conditioning installation company to set reasonable, so even if the air conditioning on a set at 25 DEG C, but after the start but will be out of the wind, a little chilly, and then to gradually cooling the air outlet. The panel temperature decreases gradually, in order to adapt to the indoor temperature is higher, and will not be a step in the air outlet panel temperature drop caused by condensation.

Q: Generator carbon brush fire how to deal with?: Carbon brush and slip ring should be inspected every day. Main inspection items are:(1) the wear length of carbon brush should not exceed 2/3. When the wear length of the carbon brush exceeds the 2/3 (i.e. the top of the carbon brush is at the same level as the top of the brush holder), it must be replaced.(2) carbon brush without sparking. When the carbon brush starts to spark, you must find out the reason and remove it in time.(3) there is no offset slip ring outside the carbon brush, and the edge of the carbon brush is not cracked.(4) the brush brush is connected with brush holder and carbon brush, without heating and touching brush holder.(5) the carbon brush has no pulsation, shaking or sticking in the brush holder.(6) regularly measure the current of each carbon brush evenly with the DC clamp type meter, and measure the carbon brush with the infrared thermometer. If abnormal, it should be replaced in time.(7) the spring pressure is normal, without deformation and fracture. Normal, the pressure on each carbon brush should be uniform and stable, the unit pressure is usually between 1.1kg ~ 2.5kg, the uneven pressure difference between the carbon brush should be less than 5%.(8) the distance between the brush holder and the slip ring conforms to the specified value. Distance between brush holder and slip ring of generator: 2.5 ~ 3 mm, distance between main brush holder and slip ring: 2~4 mm.
