The LT544D-20 and LT544D-20E Digital Safety Analyzers are portable instruments for the basic electrical safety evaluation of electrical medical devices. Their compact hand held size makes them an ideal addition to a service technician or engineer's tool box for that "after service test" as well as serving as a bench top instrument for the laboratory. They do not sacrifice functions or accuracy and their low cost permits putting one on each bench.
The analyzers are 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 analyzers utilize simple, yet sophisticated electronics for true RMS measurement of current and voltage. Input impedance uses the AAMI ESI-1985 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 input connector resistance
