The QA-ST is esigne to quickly check electrical safety on me ical
an in ustrial evices. It is palm-size an very portable. The tests
can be performe manually or in step-by-step mo e. The results are
isplaye in a bright 4- igit LCD isplay.
The QA-ST performs all electrical safety tests necessary to satisfy
AAMI ESI, NFPA-99, VDE 701, VDE 751 an HEI 95. It also features
ifferential current measurements obtaine by an internal current
clamp. This presents a new leakage current measurement technique
for convenient testing of me ical equipment with a fixe power cor
(har wire to wall, not etachable).
