DC strømmåling af smart multimeter
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.
Varsel:
1. Hvis du ikke kender det aktuelle område, der testes før brug, skal du indstille funktionskontakten til det maksimale område og gradvist reducere det.
2. Angiver, at den maksimale indgangsstrøm er 200mA. For høj strøm vil brænde sikringen ud og bør udskiftes. 20A-serien har ingen sikringsbeskyttelse, og målingen må ikke overstige 15 sekunder.
AC strømmåling
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!
