The QuadTech LR2000 Milliohmmeter with its LCD display and menu type front
panel programming assures that low resistance measurements on switches, relays,
connectors, cables, and other devices can be made quick and easy.
With a basic accuracy of 0.05% the instrument offers a wide measurement range
from 1 mΩ to 2 MΩ. For remote operation and production applications
the unit comes standard with an RS-232 interface, plus IEEE-488 and handler
interfaces are available as options. For measurement integrity, contact to the
test device is made via a 4-terminal Kelvin connection that incorporates an
automatic zeroing function to compensate for lead errors.
Wide Measurement Range: Eight measurement ranges from 20 µΩ
to 2 MΩ full scale with constant current between 1 µA and 1 A. For
"dry" contact measurements (those contacts whose resistance can be
altered by excessive voltage potential) the LR2000 can be limited to 20 mV on
selected measurement ranges.
Test Signal: Besides the standard DC test signal, the LR2000 provides
a signal reversal mode for eliminating thermal EMF's, and pulsed current mode
for minimizing errors caused by device heating.
Precision Measurements: With a basic measurement accuracy of 0.05% the
instrument makes for consistent, reliable test results.
Graphical Display: 240 x 64 dot matrix graphical LCD display for user
friendly menu programming and display of measured results.
Measurement Rate: Three measure modes of 15, 6 and 1.5 measurements
per second with varying degrees of accuracy.
Pass/Fail Testing: Provides a programmable Hi/Lo comparator function
in absolute value or %, as well as 8 sorting bins for categorization of components.
Zeroing: An automatic zeroing functions reduces the effects of lead
resistance through the front panel 4-terminal Kelvin connection.
Interfaces: For remote control, or adaptation to a production type environment,
the LR2000 includes an RS-232 interface standard. A GPIB and Handler interface
is available as an option.
Includes: Kelvin Clip Leads, AC Power Cord, User Manual, Power Line
Fuses, NIST Traceable Calibration Certificate. |
