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.
Specifications are based on a one year calibration cycle.
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
S82.02.01, EN 61010-1: 2001, CAN/CSA-C22.2 No.61010-1-04 (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.
