1. INTRODUCTION

This tester has been designed and tested according to

EN 61010-1, EN 61326-1, EN 61557-1, EN 61557-5 and

other safety standards. Follow all warnings to ensure safe 

operation.

The tester meets EN 61010-1 CAT IV 300V Electrical

test & measurement tools are assigned to 4 different 

designations from CAT I-IV (category) rating. The higher 

the category, the more risk there is that a high voltage 

can overload a circuit and cause electrical and physical 

damage. Usually, the higher the CAT rating, the safer the 

rating.
