Multifunctional power meter yog lub siab -precision, ntse vaj huam sib luag-mounted xyuas cov cuab yeej tshwj xeeb tsim los rau qis thiab nruab nrab-voltage fais fab faib tshuab hauv kev lag luam thiab pej xeem. Tsis zoo li cov khoom siv hluav taws xob ib txwm siv uas tsuas yog txhawb nqa kev ntsuas hluav taws xob nkaus xwb, cov khoom siv sib xyaw ua ke zoo sib xyaw ua ke tiag tiag- lub sijhawm saib xyuas cov ntaub ntawv, ntau- qhov ntsuas hluav taws xob, ntsuas hluav taws xob meej thiab cov teeb liab tawm hauv ib chav tsev.
Nws tuaj yeem ua tiav qhov siab -kev ntsuas qhov tseeb, suav thiab tso saib ntawm yuav luag txhua qhov qauv AC hluav taws xob tsis zoo, npog tag nrho cov ntsuas ntsuas hluav taws xob thiab qib siab uas xav tau rau kev lag luam hluav taws xob niaj hnub. Raws li lub ntsiab lus tseem ceeb ntawm cov khoom siv hluav taws xob ntse, nws tau siv dav hauv cov chaw tsim khoom lag luam, cov chaw lag luam, cov tsev ua haujlwm, cov tsev nyob thiab ntau yam kev faib hluav taws xob rau pej xeem, muab kev ntseeg siab, tiag tiag - lub sijhawm thiab cov ntaub ntawv raug txhawb rau kev tswj hwm kev lag luam, kev siv hluav taws xob thiab kev saib xyuas hluav taws xob.
