The 10A Micro-Ohmmeter Model 6240 is a rugged, low resistance tester designed for both
plant and field use. It is a cost effective, feature rich instrument designed for measuring
contact resistance, bond resistance and other low resistance connections. The Micro-
Ohmmeter Model 6240 accurately measures very low resistance with 0.25% accuracy
utilizing a four-lead Kelvin method of testing.
An internal NiMH battery pack is rechargeable from 110/230V, 50/60Hz. A fully charged
battery can perform up to 850, 10A tests.
Resistance measurements are automatically calculated from 1μΩ to 400Ω with resolutions
down to 1μΩ.
The Model 6240 has selectable test currents of 10A, 1A, 100mA and 10mA and includes a
polarity reversal function. The Model 6240 is designed to conduct tests on both resistive
and inductive material. Polarity reversal is easily accomplished with a push of a button. The
resistance measurements of both positive and negative test results, as well as the average,
are displayed.
A large easy-to-read multi-line backlit display indicates all test result information including
the resistance measurement, test current and test voltage.
An automatic test mode feature provides for repetitive tests by simply moving the test
probes from point to point, displaying the test results and automatically storing the reading
in the instrument’s internal memory for later recall and report generation.
Up to 99 measurements can be stored and printed directly to a printer or downloaded
to a PC for analysis and report generation.
An optically isolated USB port provides quick and easy downloads while protecting the PC
from any electrical interference.
The DataView ® software included allows you to: download data, temperature compensate
the test results, store data and print reports using predefined templates or custom
templates you create.
