1 Introduction

This chapter escribes the METRON QA-ST Safety Tester’s features

an specifications.

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).
