Introduction; Dual Input Oscilloscope; Vertical - Fluke ScopeMeter 123 Service Manual

2.1 Introduction

Performance Characteristics
FLUKE guarantees the properties expressed in numerical values with the stated
tolerance. Specified non-tolerance numerical values indicate those that could be
nominally expected from the mean of a range of identical ScopeMeter test tools.
Environmental Data
The environmental data mentioned in this manual are based on the results of the
manufacturer's verification procedures.
Safety Characteristics
The test tool has been designed and tested in accordance with Standards ANSI/ISA
S82.01-1994, EN 61010-1 (1993) (IEC 1010-1), CAN/CSA-C22.2 No.1010.1-92
(including approval), UL3111-1 (including approval) Safety Requirements for Electrical
Equipment for Measurement, Control, and Laboratory Use. Use of this equipment in a
manner not specified by the manufacturer may impair protection provided by the
equipment.
