DLRO100XB LG2-P3 Digital Low Resistance Ohmmeter, 100A, Battery And Mains Powered with Dual Ground, Memory Storage and USB Download + US (NEMA) Mains Plug with English, Spanish, Portuguese and Italian. (Test Leads not included)
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.
Standard test leads, with separate Current & Potential, or Kelvin, combining both Current & Potential in one clamp, are available as optional accessories in 5 m, 10 m & 15 m lengths. All test leads are CAT IV 600 VAC / 500 VDC safety rated.
For over 100 years the 'Ducter test' has been used to describe a simple test for measuring very low contact resistances and "Ducter", which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and 'Ducter' has since become the industry standard.
The needs for accurate low resistance measurement are well known and very diverse and applications differ between the electricity utilities, electrical service contractors, Original Equipment Manufacturers (OEM) and transport. Typical applications include...
Utilities & Service Contractors - commissioning new installations & regular maintenance testing of Switchgear and circuit breaker contact resistance
Original Equipment Manufacturer - detecting manufacturing defects
Transport - manufacturing & maintenance
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).
