Digital Low Resistance Micro Ohmmeter; 115 V

Measure contact resistance in high-voltage circuit breakers|Easy to ready backlit liquid crystal display|Test currents from 10 to 200 A DC|Filtered direct current output eliminates magnetic transients|On-board memory for up to 300 test results and notes|RS232 port for downloading stored results or realtime data|1 year warranty|The Megger DLRO200 test set accurately measure resistances ranging from 0.1Ω to 1Ω, at high currents. It will check the continuity of the test circuit and will quickly ramp the test current up to the desired level. The alphanumeric keyboard is used to set upper and lower limits for the test to pevent the use of excessive currents, as well as documenting / adding notes to the stored data results. The DLRO200 uses a four terminal measurement technique to cancel the resistance of the test leads from the measurement.
