How to measure the current of a sensor with a multimeter

How to measure current with a multimeter.

Electrician friends often use a multimeter, and some people call it a multi-meter, a three-purpose meter, a traditional standard, etc., mainly to measure voltage, current and resistance, etc. Many friends often buy multimeters in the family, but they don't know how to use them. The following will introduce the relevant knowledge to you.

1. How to measure the current with a multimeter.

First, insert the black watch pen into the hole of the "COM" mark of the multimeter, if the current of the electrical appliance to be measured is large, generally A level, then insert the red watch pen into the "10A" jack, and rotate the knob to the DC "10A" gear; If the electrical current to be measured is small to the MA level, insert the red watch pen into the jack of "MA", and then turn the knob to the position of DC MA gear. Once adjusted, start measuring. Insert the multimeter into the circuit, maintain stable contact, read the measurement data from the display, and record it.

2. Precautions for using a multimeter.

1. Before measuring, check whether the measured gear is selected accurately. After use, select the position of AC 750V or DC 1000V for the measurement product in the future, so that the internal components of the multimeter will not be damaged.

2. If the measured voltage or current is too large, the multimeter will be damaged and the measurement will not be possible. If you do not know the approximate range of the voltage to be measured, it is recommended to set the measurement gear to the highest setting, then measure its value and then shift the measurement to make the value more accurate.

3. Be careful not to measure the voltage directly at the current level, resistance level, etc. When the meter is being tested, remember not to rotate, especially at high voltages and currents.

4. When the battery symbol appears on the multimeter screen, it proves that the power is insufficient, and the multimeter battery should be replaced in time. After daily use, turn off the meter in time.

Conclusion of the article: The relevant knowledge of multimeter current measurement will be introduced to you here, I hope it will be helpful to you. If you want to know more about it, please continue to pay attention to Qeeka Home information platform.

Summary. Hello, the measurement of DC current should first insert the black watch pen into the com hole of the multimeter, if the measurement current is relatively large, for the A level, the red watch pen should be inserted in the 10A jack, and then adjust it to the 10A gear, if the measurement current is relatively small and belongs to the MA level, just insert the watch pen into the MA jack, and then adjust it to the MA gear, and then just adjust the gear to the appropriate position, after adjustment, you can start to measure.

Hello, the measurement of DC current should first insert the black watch pen into the com hole of the multimeter, if the measurement current is relatively large, for the A level, the red watch pen should be inserted in the debate to destroy the 10A jack, and then adjust it to the 10A gear, if the measurement current is relatively small and belongs to the MA level, just insert the watch pen into the MA jack, and then adjust it to the MA gear, and then just adjust the gear to the appropriate position, after adjustment, you can start to measure the ecstasy.

It is equivalent to training the ammeter to both ends of a circuit.

Yes. Hello, that's it.

No, no. Hello, that's right.
