The Megger DLRO10X (6111-429) Digital Low Resistance Ohmmeter sets the standard for low resistance measurement. The DLRO10X is a fully automatic instrument, selecting the most suitable test current up to 10 A DC to measure resistance from 0.1 microohm to 2000 ohms, on one of seven ranges.

The DLRO10X uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current. The instrument is built into a strong, lightweight case that is equally suitable for use in the field or in the laboratory. Light enough to be worn around the neck, it is small enough to be taken into areas that were previously too small to access.

The DLRO10X 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%. The DLRO10X displays both forward and reverse measurements as well as the average of the two. It furthermore allows the user to set high and low pass limits, thereby enabling simple go-no-go testing.

The DLRO10X is supplied with a Nickel Metal Hydride (NiMH) battery pack. The battery packs are interchangeable 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 monitored, even without being connected to the instrument.

The DLRO10X 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 the DLRO10X complete with notes containing up to 200 characters which may be added using the on board keypad. These results can also be downloaded to a PC.
