1. Introduction
This chapter describes the QA-90 Electrical Safety Tester’s features
and specifications.
1.1 QA-90 Features
The QA-90 represents a new generation of safety testing equipment. It
is the only automatic safety analyzer that can test units with different
classes of protection in one test run (e.g., cardiac float and body float
defibrillators). It is simple to use. All you need do is select the type
and class of equipment to test. When you press START, QA-90 ex-
ecutes the tests prescribed to the selected standard.
Test results may be printed out immediately, or stored internally in the
unit for later use. QA-90 has full remote control, and may be operated
from PRO-Soft QA-90 software. PRO-Soft QA-90 enables you to
make your own test protocols, store the information on disk, and ex-
port formatted data to any other database or equipment management
program. Individual test sequences may be compiled to satisfy na-
tional and international standards.
The following standards may be compiled either fully or in part:
IEC 60601.1, UL 2601.1, IEC 60601.1.1, UL 2601.1.1, IEC
60601.2.4, IEC 61010-1, EN 60601-1, VDE 0750 Tl/12-91, BS 5724,
CAN/CSA-C22.2 No 601.1-M90, AS 3200.1, NZS 6150:1990, VDE
0751 T1/12-90, ÖVE 0751, UL 544, HEI 95, HEI 158 among others.
