Page 6: Introduction
2 INTRODUCTION Introduction The SVERKER 650 is a rugged instrument but it still should be handled with care. The relay testing unit is electrically fully isolated in all measuring ranges, except for the mains output. The set of resistors is not connected with the rest of the relay testing unit set. - Page 7 3 CONTROl PANEl BA0143KE ZP-BA01E SVERKER 650...
