The Megger DLRO 10X is a fully automatic instrument, selecting the most suitable test current, up to 10 A dc 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 manual selection of the test current.
A resistance measurement takes approximately 2.5 seconds and comprises a measurement with forward current, reverse current and a display of the average. On the DLRO 10X all three values are displayed, and optionally, the measurement may be limited to forward current only.
All the controls needed to set up and operate megger DLRO 10X are located on the top panel of the instrument. To the left of the large LCD display are the controls for moving around the display, controlling the menuing system and adjusting the display contrast and backlight. To the right of the display is the large Test button, Power On/Off button and an alphanumeric keypad for entering notes relating to a test which will be stored with the test results for later reference.
The DLRO10X is powered by a rechargeable Nickel Metal Hydride (NiMH) battery, which permits one thousand 10 Amp tests to be completed on a single charge. The battery module contains intelligent circuitry, which prevents damage to the battery from overcharging, and a battery state indicator. A removable lid that is hinged at the back and held closed by magnetic catches covers the top panel. This lid may be removed if required by opening fully and snapping out of its hinges.
Up to 700 sets of results may be stored within Megger DLRO 10X complete with notes containing up to 200 characters which may be added using the on board keypad.
Accurate results in under three seconds.
