Description
The AEMC 6255 10 A micro-ohmmeter 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 6250 is one of the most accurate micro-ohmmmeters available with results up to 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 AEMC 6255 with an external RDT temperature probe.
The AEMC 6255 micro-ohmmeter 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 ther 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.
