The QA-ST is designed to quickly check electrical safety on medical
and industrial devices. It is palm-sized and very portable. The tests
can be performed manually or in step-by-step mode. The results are
displayed in a bright 4-digit LCD display.
The QA-ST performs all electrical safety tests necessary to satisfy
AAMI ESI, NFPA-99, VDE 701, VDE 751 and HEI 95. It also features
differential current measurements obtained by an internal current
clamp. This presents a new leakage current measurement technique
for convenient testing of medical equipment with a fixed power cord
(hardwired to wall, not detachable).
