The 10A Micro-Ohmmeter Model 6250 is a rugged, low resistance tester designed for plant maintenance, quality control in manufacturing and field use. Utilizing a four-lead Kelvin method of testing, the Model 6250 is one of the more accurate Micro-Ohmmeters available, with results within 0.05% accuracy.

Resistance measurements are automatically calculated and displayed, taking into account the measurement value, ambient temperature, reference temperature and metal temperature coefficient. Sample temperature can be manually entered by the operator or directly measured by the Model 6250 with an external RTD temperature probe.

The Model 6250 is uniquely designed to conduct tests on both resistive and inductive material, with operator selection directly from the front panel.

Three test modes are available and automatically employed based on this selection:

  • Resistive materials (i.e. ground bonding, coatings, contact resistances) are tested with an instantaneous test. Simply press the test button – the reading is taken and the test is concluded.
  • Inductive materials (i.e. coils, transformers, motor windings) are tested with a continuous test. The test is started and stopped by the operator at the push of a button.
  • Auto test mode is designed for multiple test points on resistive and/or low inductance material. The test is started at the press of a button. As the operator moves the probe from one point to another, the test is stopped, the results are displayed and a new test is started when the test probes again make contact – no need to press the test button! Residual voltage is measured between tests to ensure proper results. This test mode continues until the operator presses the button to conclude the testing.

The large, easy-to-read display shows the resistance measurement, ambient and reference temperatures, metal type and test method, as well as alarm conditions and memory utilization, all in real time. Previously stored test results can easily be called up for review on the display or sent directly to a printer or remote terminal.

External trigger operation is available through the communication port allowing the test to be conducted from a remote location.

The list of features and functions goes on and on. The Model 6250 will be a valuable asset for your bond testing, coil and contact testing as well as coatings and connector or any other low resistance testing application.
