Q: Clamp ammeters how to measure resistance, current, voltage: Not all the same with the clamp meter multimeter can measure resistance, voltage and current.Clamp meter is mainly to test current (especially large current) and design, so some clamp meter to measure the current only.

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: Emerson DC panel: Battery current display -0.5A, processing method, the first step, Holzer 0 points fine tune, just let the battery current display 0~0.5A just fine.Display 50AH, because the battery current -0.5A, has been discharged, so the capacity is low, with user level password into the monitoring, restoration of the nominal capacity of the battery just fine.

Q: But after 3 minutes on the machine, there is no electricity, what's the matter?: At first glance, under cooling state, adjust the temperature controller to the user, set the temperature 6 degrees lower than room temperature time temperature to 8 DEG C in 15 minutes after running, the normal air conditioning in the indoor machine hydraulic pipe should be no frosting phenomenon, if this phenomenon if there is leakage of fluorine failure. If there is a hydraulic pipe connector of indoor machine oil, which also shows that air conditioning has produced fluorine leakage phenomenon.Followed by touch, touch the air conditioning after the condenser shutter fan, if the hand temperature is not changed, and the compressor at work, which means that the fluorine has been run. Because the compressor is working, there is no heating or cooling.If you find that the compressor has been working since it started, there is no vibration of the compressor, and the sound of the compressor self shock is larger than that of the newly purchased air conditioner. This may be the abnormal sound caused by leakage of fluorine.Finally, temperature measurement. Find a thermometer, close to the air outlet, look at the thermometer indicates whether 6 to 8 DEG C lower than room temperature, as shown in the temperature lower than the indoor temperature less than 5 degrees even at room temperature and not much difference between, continues and the compressor work, it shows that air conditioning fluoride may have leaked.

Q: Taiyuan Wittel QJR soft start switch current unbalance fault is what reason?: In operation, measure whether the three-phase current of the load end is equal with a caliper table, or whether the three-phase current is measured together to see whether the current is zero!

Q: 20kW motor running for some time will trip what is the reason?: Air capacity is small, the fever will trip

Q: Who can specifically describe the automatic conversion range function, and some automatic?: Diode test: shows the forward conduction voltage of an approximate diode. Used to measure the transistor characteristics of diodes and transistors. Diode measurements: test current digital multimeter resistance profile provided is very small, in the positive resistance measuring diode, transistors and other nonlinear components, several times higher than even a few times measuring pointer multimeter resistance profile values, this is a normal phenomenon. It is recommended to use the digital diode meter of diode meter to measure the positive and reverse voltage drop of diode PN junction to judge the unidirectional conductivity of diode.

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: Electric drills, electric saws and so on. Under what circumstances should carbon brushes be used?: Brush (Carbon brush) also known as brush, a sliding contact, is widely used in many electrical equipment. Carbon brushes are mainly used in products such as graphite, impregnated graphite, and metal (including copper, silver) graphite. The carbon brush is the energy transfer device or signal between motor or generator or other rotating machinery of the fixed part and the rotating part, it is generally made of pure carbon coagulant, the general shape is square, stuck in the metal bracket, which has spring pressed it on the shaft, when the rotation of the motor, the power through the change which is delivered to the coil, as its main components are carbon, known as carbon brush, it is easy to wear. Regular replacement, cleaning and carbon deposition shall be maintained.
