Tomhas reatha DC ar multimeter cliste
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.
Fógra:
1. Mura bhfuil a fhios agat an raon reatha faoi thástáil roimh úsáid, socraigh an fheidhm lasc go dtí an raon uasta agus é a laghdú de réir a chéile.
2. Léiríonn sé gurb é 200mA an sruth ionchuir uasta. Beidh an iomarca sruth sruthán amach an fiús agus ba chóir a chur in ionad. Níl aon chosaint vacuum ag an raon 20A, agus ní féidir leis an tomhas a bheith níos faide ná 15 soicind.
Tomhas AC reatha
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!
