Digital Multimeter Resistance Measurement Considerations
Thaum ntsuas kev tiv thaiv online, cov kab hluav taws xob yuav tsum raug muab tua thiab tag nrho cov capacitors yuav tsum raug tso tawm tag nrho.
· Yog hais tias qhov ntsuas tsis kam yog qhib Circuit Court lossis tus nqi tsis kam tshaj qhov siab tshaj plaws ntawm lub ntsuas, lub ntsuas yuav tso saib "OL".
· Thaum ntsuas qhov tsis kam siab tshaj 1MΩ, nws yuav siv sij hawm ob peb lub vib nas this rau lub 'meter' kom ruaj khov rau kev nyeem ntawv, uas yog ib txwm muaj rau kev ntsuas siab.
· Thaum ntsuas qhov tsis kam, thov tsis txhob muab tus nqi hluav taws xob, txwv tsis pub kev nyeem ntawv yuav tsis raug. Yog tias nws tshaj qhov hluav taws xob tiv thaiv overload ntawm 250V, nws yuav ua rau cov cuab yeej puas thiab ua rau muaj kev nyab xeeb ntawm cov neeg siv.
· Tom qab qhov kev ntsuas tiav lawm, tam sim ntawd tshem tawm cov kev xeem coj los ntawm lub voj voog nyob rau hauv kev sim.
