DLRO 10 and DLRO 10X Digital Microhmmeter DLRO 10 and DLRO 10X Digital Microhmmeter ■■ NEW interchangeable test lead terminations ■■ Auto current reversal cancels standing emfs ■■ Protected to 600 V ■■ Automatically detects continuity in potential and current connections ■■ Multiple operating modes including fully automatic ■■ Alpha-numeric keypad for entering test notes (DLRO 10X) ■■ User selectable high and low limits (DLRO 10X) ■■ Printer output and memory (DLRO 10X) DESCRIPTION DLRO 10 and DLRO 10X set the standards for low resistance measurement, also known as the Megger ‘Ducter™’ test. made with forward and reverse currents to cancel the effects of any standing voltages across the test sample. History of ‘Ducter’ testing The average value is then displayed within 3 seconds, to a basic accuracy of 0.2%. DLRO 10X displays both forward and reverse measurements as well as the average of the two. 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. DLRO 10 and DLRO 10X are fully automatic instruments, selecting the most suitable test current up to 10 A d.c. to measure resistance from 0.1 μΩ to 2000 Ω, on one of seven ranges. For users who desire more control over the measurement process, DLRO 10X uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current. DLRO 10X also adds real time download of results and on board storage for later download to a PC. Both instruments are built into a strong, lightweight case that is equally at home in the field or in the laboratory. Light enough to be worn around the neck, they are small enough to be taken into areas that were previously too small to access. DLRO 10 uses a large, bright 4 1/2 -digit LED display while DLRO 10X has a large, backlit LCD display. Normally, measurements are DLRO 10X allows the user to set high and low pass limits, thereby enabling simple go-no-go testing. At the end of a test DLRO10X will store the test results, as well as any notes relevant to the test. To ensure customers are able to choose the best test leads to suit their application, the DLRO10 and DLRO10X may be purchased in one of two packages. The first option is supplied with a pair of duplex handspikes with 1.2 m (4 ft) leads, the second option is supplied without test leads to allow customers to order exactly the test leads they require from the accessory list. The instruments are supplied as standard with a Nickel Metal Hydride (NiMH) battery pack. The battery packs are interchange-able so that an exhausted battery may be recharged using the external charger supplied while testing continues using a spare pack. Although full charging will take 4 hours, a fast charge mode allows the battery to be 90% charged within 2 1/2 hours from a 12 volt battery or from a standard 120/230 V AC supply via the supplied charger. The battery pack contains its own battery state indicator, which allows the charge-state to be moni

DLRO 10 and DLRO 10X Digital Microhmmeter In addition an optional mains / line power supply, the DLRO10LPU is available. This enables the instruments to be directly powered from 90V to 264V, 50/60Hz ideal for repetitive testing applications such as manufacturing production line use. DLRO 10X is fitted with RS232 communications that will allow results to be downloaded in real time or stored for later retrieval. Up to 700 sets of results may be stored within DLRO 10X complete with notes containing up to 200 characters which may be added using the on board keypad. These results can also be downloaded to...
