The Megger DLRO10 + DH4-C (1006-598) Digital Low Resistance Ohmmeter sets the standard for low resistance measurement. The DLRO10 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 DLRO10 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 DLRO10 uses a large, bright 4 1/2 -digit LED 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 DLRO10 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 DLRO10 + DH4-C is supplied with the DH4-C 1.5m Duplex Connect Handspike Lead Set, which features terminations that may easily be changed as required.
