VFD Voltage Measurement Ntawm GVDA Tshiab Tuaj Txog GD169A Digital Clamp Meter Tseeb RMS

VFD Voltage ntsuas ntawm GVDA Tshiab tuaj txog GD169A Digital Clamp Meter Tseeb RMS:

1) Tig lub pob qhov rooj raulos yog, Xovxwmtseem ceeb kom txog thaum lub cim "VFD" tshwm

2) Ntxig liab sojntsuam rau "INPUT" jack, ntxig dub sojntsuam rau "COM" jack.

3) Txuas qhov kev sojntsuam nrog qhov hluav taws xob lossis ob qhov kawg ntawm cov khoom thauj khoom sib npaug rau kev ntsuas

4) Nyeem qhov ntsuas ntsuas ntawm cov zaub

CEEB TOOM

l Ua ntej siv, siv lubmetertxhawm rau kuaj qhov paub qhov voltage lossis tam sim no, thiab paub meej tias qhovmeternyob zoo

l Ua tib zoo saib xyuas kev nyab xeeb thaum ntsuas qhov hluav taws xob siab kom tsis txhob muaj hluav taws xob poob lossis raug mob ntawm tus kheej

l Thov tsis txhob siv VFD muaj nuj nqi los xyuas qhov muaj qhov txaus ntshai voltage lossis tam sim no, uas tej zaum yuav tshaj tus nqi qhia kom tsis txhob muaj hluav taws xob poob lossis raug mob ntawm tus kheej.

CEEB TOOM

l Thaum siv(tsawg input impedance) kev ntsuas, lub sij hawm ntsuas tas li tsis tuaj yeem tshaj 1 feeb.

l Tsis txhob siv LoZ hom los ntsuas qhov hluav taws xob hauv circuits uas yuav raug puas tsuaj los ntawm qhov qis impedance ntawm hom no.
