FAQ

Can the fluke317 clamp meter test DC current?

But the switch is not allowed to operate when charged. Clamp meter general accuracy is not high, usually 2.5 ~ 5. In order to facilitate the use of the table there are different ranges of switching switches for measuring different levels of current and voltage measurement function. Clamp meter is composed of a current transformer and current meter assembly. The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can be cut through the opening of the iron core without cutting off, and when the wrench is released, the iron core is closed. Through the test circuit of the core, the wire becomes the primary coil of the current transformer, in which the current is induced in the two coil through the current. A current meter connected with the two coil is then instructed to measure the current of the line being measured. A table can shift through the switch, the scale change. But the switch is not allowed to operate when charged. Clamp meter general accuracy is not high, usually 2.5 ~ 5. In order to facilitate the use of the table there are different ranges of switching switches for measuring different levels of current and voltage measurement function.

How to find out the broken capacitor in the three-phase capacitor of the reactive compensation cabinet with the clamp table?

Use clamp meter measuring each capacitance of each phase current, no current is failure, current ratings than too much capacity loss.In fact, do not need to use a clamp meter measurement, the reactive power compensation cabinet in manual operation, and observe the 3 input capacitance by monitoring the current cabinet said the number and capacitance rating (each) to determine whether the sum of.

How to auto discharge clamp current meter

Clamp ammeters referred to as clamp meter.The work is mainly composed of an electromagnetic current meter and bushing type current mutual inductor. Straight through current transformer core made of movable opening, and a clamp on ammeter, named. The utility model is a portable instrument which can directly measure the alternating current of the circuit without disconnecting the circuit, and is very convenient for use in the electrical overhaul, and is widely used.

Use clamp ammeters, wire requirements will be placed in the window center. Why is this?

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.

BM822A type digital clamp meter is how to measure current?

Each phase current is measured separately, and the current in the rated range is its load current, exceeding the rated value, and the current is its overload current. A table definition: clamp type table (sometimes called 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 test precision, resolution and more test function.

How to test the current on a motor?

String into the known small resistance, take the resistance on the pressure drop, memory oscillograph to record the waveform, and then converted to the current value.If an electric current clamp is used, the current clamp is certainly possible, but it is necessary to understand the proportional relationship between the current clamp and the transmitted signal.Resistance sampling is simple and practical.

How can the air outlet of the air conditioner in the air conditioner flow out?

In the refrigeration operation, look at the dripping pipe, dripping speed is very slow, or no water drop. (for more than an hour after the boot does not drop or drop slow, mostly refrigerant leakage), the horizontal position of indoor machine improper installation: indoor machine installed in a horizontal position inclined pipe intersection direction caused by excessive condensation water efflux blocked.

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.
