AC voltage test preferred
Usage examples
  • Test of dielectric strength (test No 1) The a.c. voltage test shall consist of applying an alternating voltage at a frequency of 50 Hz and an effective value of 2 kV for one minute between all the inter-connected terminals and the flat metal surface on which the meter is placed.

  • testimine numbrilise multifunktsionaalne mõõtevahendiga, mille puhul on nupp seatud vahelduvpingele, must sond sisestatud COM-porti ja punane sond sisse ning sondide otsad pingestatud vooluringiga, nt 120 V/240 V pistikupesa, ühendatud.
  • pingeteim, mis 1 minuti jooksul peab olema rakendatav sagedusvahemikus 45 Hz kuni 65 Hz ning reaalselt siinuseline, ning pingeallikas peab kindlustama 500 VA toitevõimsuse
  • test voltage that is substantially sinusoidal, of rated freuency, and be applied for 1 min
  • testing with a digital multimeter, that set the dial to AC voltage, insert the black probe into COM and red into, and connect the probes to the live circuit (e.g., a 120 V/240 V outlet)
vahelduvvoolu pingeteim
Usage examples
  • Vahelduvvoolu pingeteimi korral puudub polaarsus, kuid ohutus on oluline: ärge puudutage sondi otsi ja veenduge, et mõõtepiirkond oleks eeldatavast pingest kõrgem.
vahelduvvoolu pingekatse
vahelduvpingekatse
Usage examples
  • Vahelduvpingekatse ajal tuleks madala nimiväärtusega alalisvoolulülitite klemmid maandusega ühendada.
AC voltage test
Usage examples
  • AC voltage test has no polarity, but safety is key: do not touch the probe tips, and ensure the range is higher than the expected voltage.
  • During the AC voltage test, the terminals of the low rating DC switches should be connected to the earth.
