Introduction
The DALE601/601E Electrical Safety Analyzer, hereafter referred to singly as
the Analyzer, is a simple, highly versatile, and portable instrument. The
Analyzer is used to evaluate the basic electrical safety of electrical systems,
medical devices, and physiological instrumentation, and a broad range of
external measurements, as listed under Key Features.
Its compact handheld size makes it an ideal addition to a toolbox, as well as
serving as a bench top instrument for the laboratory. The Analyzer does not
sacrifice functions or accuracy, and its low cost permits putting one on each
bench.
Simplicity
The Analyzer is simple to use, incorporating the following:
• A single, labeled master function switch that leads the user through a
complete specific measurement procedure
• A single range meter for each measurement that minimizes the chance of
erroneous readings
• Heavy-duty switches that change polarity, open and close the neutral, and
select chassis or earth leakage current measurements
• A single slide switch that gives the user a choice of AAMI or IEC test
load
• Five universal EKG lead connectors that allow for any type of lead
connection
• Green and amber lights that indicate five power line conditions
The Analyzer uses sophisticated electronics for true rms measurement of
current and voltage. Input impedance uses the manually selectable AAMI ES1-
1993 or IEC601-1 test load to compensate for high frequency components in
the measurement. Resistance measurements are made with a four-wire Kelvin
bridge to eliminate errors resulting from cable length and connector resistance.
