FAQ

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

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.

Generator carbon brush sparks, how to deal with?

From the following points: 1. check out whether the brush length is too short to cause the lifeline, the pressure is too small not brush contact ring; 2. check the spring pressure pressure is appropriate, if too small will lead to jump 3. check slip ring brush discharge; surface finish, if too much hair will increase the brush contact resistance of spark; 4. check the rotor electrical resistance, ensure the normal, no inter turn short; 5. check whether the oil bearing gap is too large, resulting in rotor slip ring brush runout, radial runout check slip surface is too large. The brush spark causes sparks; 6., whether the brush is the same as before, the brush has a requirement for the conductive current and the friction speed.

Current detection small current

Clamp type table is a common AC current (AC) measurement tool, but the current small bad measurement time can be measured in the wire clamp meter on laps around the table, the current display number / number of turns = actual.

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 select the clamp meter?

According to your needs test range, select the range of the current, generally the largest 600A, according to your habits, choose digital or pointer type.

How does the 36V transformer change the starting power of the car?

Then the electricity for clamp meter to measure the current, if the battery is charged with a current of 100 ampere 10 or so, if the current is large the 220 volt power supply terminal receives 380 volts, then 220 volt power supply, current will drop, anyway, this transformer can meet your needs. Adjust the voltage until satisfied.

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:

The difference between digital multimeter and caliper type multimeter

Clamp type ammeter and multimeter principle using different methods are not the same. As long as the table clamp clamp a wire can measure the current, suitable for high current measurement, the multimeter measuring current but is connected to the circuit, otherwise can not be measured. The multimeter measured current to the circuit are connected in series go
