Information
ESI's Model 2100/2110 Auto LRC Meters are two extremely
versatile impedance measuring instruments. They feature
variable test frequencies (~3000), programmable test-signal
levels, component sorting, and CRT displays. They measure
inductors (L), resistors (R), capacitors (C) , and display
up to 10 impedance characteristics in 26 different
combinations. Basic accuracy of 0.05% added to the widest
ranges available for passive component measurements make the
2100/2110 the most informative impedance measuring
instruments available today.
Mass storage for test parameter setups and measurement
results is the feature that set the Model 2110 apart from
the Model 2100. The 2110 has a cassette tape loader that
uses mini-cassette tapes for storing and reloading test
parameter programs.
The 2100/2110 measurement system is basically composed of a
frequency selectable, digital sinewave generator, a
test-level regulator, precision range resistors, a
phase-sensitive voltmeter, and a charge balancing
analog-to-digital Converter. All measurements, calculations,
and displays take place under the watchful eye of the 2100/
2110's Z80 microcomputer.
