The manual test mode allows the user to initiate the test procedure once the probes are in contact with the object under test. Once the TEST button is depressed the TEST lamp will illuminate and the instrument will undertake a single test to verify the resistance of the test object.
In auto mode the user selects the desired current, connects the current test leads and as soon as the potential leads are connected a test will start automatically. To repeat a test, simply break contact with the potential probes and remake contact.
In continuous mode the user connects the test leads and presses the TEST button, initiating the test procedure. The instrument will continue to test, updating the display after each new test cycle, until the TEST button is pressed or the test procedure times out.
The new Megger DLRO100 series offers a unique range of 100 A digital low resistance testers. Never before has CATIV 600 V safety, operational IP54 ingress protection for dust and water, and lightweight, fast charge, Li-ion battery technology been available on a continuous 100 A low resistance tester.
Providing low resistance measurements across a multitude of applications, including areas without access to line power, the DLRO100 is extremely flexible. Applications include switchgear, circuit breaker contact resistance, bus bar and cable joints, wire and cable resistance, lightning conductor bonding, welded joints, ground connections and joints.
DLRO100X & DLRO100H include DualGround feature, which adds to the operator’s safety by grounding both sides of the breaker being tested. These models also including the ability to save, download and delete results.
Megger has taken a no compromise approach when designing the new DLRO100 series. The range offers a unique combination of features with everything including DualGround™ testing, adjustable current ramping, high noise immunity, high power 100 A continuous testing and even remote control, yet still manages to be small and lightweight.
There are three models in the series, all three models can be line powered, are rated CAT IV 600 V and can test currents from 10 to 110 A. B in the model name indicates the battery powered option (in addition to AC power).
