Q: Can the 5 (20) A meter withstand the current of 30A?: 5 (20) A stands for this meter, allowing long running currents not exceeding 20A, instead of representing 20A for a short period of time. As for the meaning of that 5, nor is it representative of the rated current, but should be called the reference current. It is a benchmark used in the inspection and test of electric meters, such as detecting the light load of electric meters. The full load。 Starting current. And so on, that's the percentage of this 5A. For example, when the current reaches 1% of 5A, it can measure accurately, and achieve the standard of accuracy, such as measuring the accuracy of the meter under the ratio of 1%, 10%, 50%, 70%, 100%, etc. of 5A. As a reference, this parameter is meaningless to the user.

Q: How to accurately measure the Ma level current: Try a Fluke 77X Ma level process caliper table. Simple and clear.If you are going to elaborate on the principles and processes, that's a thesis.

Q: Methods use a table clamp type table and the matters needing attention: The measurement in high voltage loop, 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.

Q: A selection table clamp type table: When the jaw is closed in the measurement, if the noise is closed, the jaw can be closed again. If the noise can not be eliminated, the joint surface of the magnetic circuit should be checked whether it is bright and clean and clean when there is dirt.

Q: A fire was found with a ground electricity? Stealing electricity.: To do so is very dangerous, prone to accidents, in case the public grounding wire grounding resistance is large, it will cause the water running electricity, indirectly causing electrocution, death accident, that would be troublesome

Q: Clamp meter cable direction? Why do I change the direction of measurement with a cable, the current is not the same: There is no direction in the clamp table and the card line. This is what you said

Q: How to measure the static grounding resistance: The grounding resistance tester model is ZC29B. There are three lines: 20 meters of ground pile and 40 meter stake respectively

Q: How does the multimeter measure Ann?: General multimeter can only measure 500 mA, type 500 multimeter, maximum measurement of 5 ann.

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.

Q: Use clamp ammeters, wire requirements will be placed in the window center. Why is this?: In the use of clamp ammeters before should carefully read the manual to find out AC or AC / DC clamp meter.
