Pengukuran arus DC multimter pintar
①Insert the black test lead into the COM jack, when measuring the current with the maximum value of 200mA, insert the red test lead into the mA jack, and when measuring the current with the maximum value of 20A, insert the red test lead into the 20A jack.
②Set the function switch to the DC current range A-range, and connect the test leads to the load to be tested in series. When the current value is displayed, the polarity of the red test leads will be displayed.
Notis:
1. Jika anda tidak mengetahui julat semasa yang sedang diuji sebelum digunakan, tetapkan suis fungsi kepada julat maksimum dan turunkannya secara beransur-ansur.
2. Menunjukkan bahawa arus masukan maksimum ialah 200mA. Arus yang berlebihan akan membakar fius dan harus diganti. Julat 20A tidak mempunyai perlindungan fius, dan ukuran tidak boleh melebihi 15 saat.
Pengukuran arus AC
The measurement method is the same as 1, but the gear should be switched to the AC gear. After the current measurement, the red pen should be inserted back into the "VΩ" hole. If you forget this step and directly measure the voltage, the meter or power supply will be scrapped!
