FAQ

How to measure the motor current with a multimeter?

Measurement of direct current. The first black probe into "COM" hole. If the measured current is more than 200mA, will be the red pen into the "10A" Jack and the knob to direct "10A"; if the current measurement is less than 200mA, the red pen into the "200mA" Jack will knob to the appropriate range of DC within 200mA. When adjusted, it can be measured. String the multimeter into the circuit and keep it steady until you read it. If the display is "1.", then to increase the range; if the numerical left "-" appears, indicates that the current from flowing into the black pen multimeter.

How to measure low voltage line grounding with pliers

Two lines, three lines or four lines at the same time through the current clamp meter is 0 normal without grounding. If there is an electric current indicating leakage, it is possible to ground.

30mA leakage breaker trip home is always with what method to find the leakage point, with clamp ammeters how?

If it is tripped when using an electric appliance, it is suspected that there is a problem with the appliance.Check the short circuit with a multimeter of the resistance can be, in the case of power failure to detect each branch of the line of fire on the zero line resistance, the resistance is too small (a few ou, even as 0), indicating that there may be a short circuit.

How to use the clamp ammeters

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.

20kW motor running for some time will trip what is the reason?

Is likely to open itself, if it is used for a long time in the air this phenomenon occurs, especially the switch lockage under heavy load especially, and tripping times more frequent. I suggest you change a new open space

How to use the caliper and its working principle?

A multimeter is made according to the principle of the current transformer, specially used for measuring alternating current.

What do you mean by measuring current 2/20 and 200/600 stalls by clamp type?

It's the measuring range [you said range value]. Not proportion!2, there is no special 100A file in this table.If you measure 100A, you'll have to put it in the 200/600 file. The accuracy of measurement readings is affected.3, such as the single insulated wire energized in a clamp meter on a circle around, and then put the readings divided by 2, can improve the measurement accuracy of 100A said.

Electric drills, electric saws and so on. Under what circumstances should carbon brushes be used?

If the power tools are stationary or not turned, they should be changed basically, unless the motor is burned;
