Introduction
The Fluke Biomedical 180 Electrical Safety Analyzer, hereafter referred to as
the “Analyzer”, is a highly versatile and portable instrument. It is used for the
basic electrical safety evaluation of electrical systems, medical devices and
physiological instrumentation. Its compact handheld size makes it an ideal
addition to a service technician or engineer's toolbox for that "after service
test" as well as serving as a bench top instrument for the laboratory. It does not
sacrifice functions or accuracy, and its low cost permits putting one on each
bench.
Simplicity
The Analyzer is simple to use. A single master function switch, directly
labeled with the test to be performed, leads the user through a complete
measurement procedure. A single range meter for each measurement avoids
potential erroneous readings.
The Analyzer utilizes simple, yet sophisticated, electronics for true-rms
measurement of current and voltage. Input impedance uses the AAMI ES1-
1993 test load to compensate for high frequency components in the
measurement. Resistance measurements are made with a four-wire Kelvin
bridge to eliminate errors due to cable length and connector resistance.
Versatility
Unique to the Analyzer is its capability to make a broad range of point-to-point
measurements. These include leakage current and/or voltage gradients and
resistance between two points. Also, the Analyzer provides the voltage and
measuring provision for the independent measurement of the isolation current
of a device. Thus the Analyzer provides the additional versatility for
evaluation of electrical systems, system installation, separate components,
isolation of probes, transducers, and conventional leakage current
measurements.
