The Megger Ducter DLRO 10X is a fully automatic micro-ohmmeter, used for performing low resistance measurements. A low resistance reading, also known as a ducter test is a simple four wire test with the objective of measuring very low contact resistance.
Automatically selecting the most suitable test current, up to 10A, the DLRO 10X can measure resistance from 0.1µ? to 2,000?, across seven ranges.
Built around the same framework as the DLRO 10, the DLRO 10X is designed for those users who require a greater degree of control over the test process as it uses a menu system controlled by a paddle which allows the user to select the maximum test current to be applied. Additionally, the DLRO 10X has a number of other upgraded features over the entry level DLRO 10, such as the ability to download results in real time and on board storage for downloading test results to a PC, and the ability to set high and low pass limits, making the test process as easy as a pass or fail.
Built into a robust, lightweight case, the Megger DLRO 10X is light enough to be worn around the user's neck but also suitable for field, production or test laboratory use, and due to it's reduced size, the DLRO 10X can be taken into areas that were previously too small to access.
In order to cancel out the effects of any standing voltages across the test sample, the Megger DLRO 10X utilises forward and reverse currents and displays the average value to a basic accuracy of 0.2% within 3 seconds on the large, backlit LCD screen.
The DLRO 10X is supplied as standard with a rechargeable Nickel Metal Hydride (NiMH) battery pack, which is interchangeable meaning that a flat battery can be recharged with the external charger, while testing continues with a spare pack. Full charging is generally accomplished in approximately 4 hours, but a fast charge mode will charge a battery to 90% of it's capacity in around 2 1/2 hours from the supplied mains charger, or from a 12V battery. The battery pack also contains it's own internal battery state indicator, allowing the state of charge to be monitored, even without being connected to the instrument.
