DLRO 10 and DLRO 10X Digital Microhmmeter

March 11, 2009
DLRO 10 and DLRO 10X set the standards for low resistance measurement. DLRO 10 and DLRO 10X are fully automatic instruments, selecting the most suitable test current up to 10A d.c. to measure resistance from 0.1 µ½ to 2000 ½, 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 made with forward and reverse currents to cancel the effects of any standing voltages across the test sample. 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. 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.• Accurate results in under three seconds • Auto current reversal cancels standing emfs • Fuse protected to 600 V • NiMH battery reduces weight • 250 mW power limit (with optional override) to avoid heating the test sample • Automatically detects continuity in potential and current connections • Visible warning of high voltages present at the terminals • Visible warning of current flowing in the test sample • Multiple operating modes including fully automatic • Alpha-numeric keypad for entering test notes • User setable high and low limits • Autoranging with Manual option • Printer output and memory
