Technical Data

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 technical data
are based on the results of the
manufacturer’s verification
procedures.

Safety characteristics

The ScopeMeter 123 test tool
has been designed and tested
in accordance with ANSI/ISA
S82.01-1994, EN 61010.1 (1993)
(IEC 1010-1), CAN/CSA-C22.2
