Merjenje enosmernega toka pametnega multimetra

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.

Opaziti:

1. Če pred uporabo ne poznate preizkušenega tokovnega obsega, nastavite funkcijsko stikalo na največji razpon in ga postopoma zmanjševanje.

2. Označuje, da je največji vhodni tok 200 mA. Prevelik tok bo pregorel varovalko in jo je treba zamenjati. Območje 20A nima zaščite z varovalkami in meritev ne sme presegati 15 sekund.

Merjenje izmeničnega toka

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!
