FAQ

How much can the current clamp measure up to? How much accuracy can be achieved?

The measuring range of this caliper meter can be great, but the accuracy depends on the manufacturing process.I am in charge of the Japanese HIOKI, the largest range of 1000A, accuracy of 1.5%; this is already quite sophisticated in the industry.

How can I measure the voltage and current with a clamp?

Using the method of measuring current clamp meter 1, before measuring clamp meter mechanical zero; 2, select the appropriate clamp meter range: from large to small range or see rating estimation; 3, when using the clamp meter minimum range measurement, the reading is not obvious, can be measured wire around a few turns the number of turns, turns to the jaw central subject is reading indication / full range X = partial x turns; 4, when measured, should make the measured conductor in the central and the jaw, jaw tight closing, in order to reduce the error; 5, after the measurement, to convert the clamp meter switch in the most in the range.

Clamp ammeters how to measure resistance, current, voltage

Usage:Although the clamp meter is similar, but each kind of table usage due to the design of the use of different methods are also different, so the user must read the instructions carefully before use.To be on the safe side, here are the main methods, but still want to read the manual. To measure the voltage and the resistance and the basic multimeter, using the pen pen insertion holes

Measurement of AC and DC dual-use electrical instruments, overload ability of the instrument for?

Electromagnetic type can.

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

Excuse me, great God. What is a DC clamp type?

Clamp type table (sometimes called the table clamp, clamp 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. It works the same way:

(1) mechanical zeroing is necessary before measurement(2), read the instructions carefully before use in the clamp meter, it is AC or DC, AC and DC.(3) 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.(4), current clamp meter only measuring one conductor, the measured wire clamp should be placed in the center of the window, can not be multiphase wires into the measurement window.(5), clamp meter before measurement was estimated the size of the current, and then decide which one range. If unable to estimate, can be the first to use the maximum range and appropriate for small files, with accurate readings. Cannot be used to measure small current file current. In order to prevent damage to the clamp type table.(6) pliers type table jaws should be closed in measurement. If there is noise after closing, the jaw can be opened once again. If the noise still can not be eliminated, it should check whether the joint surfaces of the magnetic circuit are bright and clean, and wipe clean when there is dirt

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.
