Digital Low Resistance Ohmmeters (DLRO®) are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control.

They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of ±0.25% and resolution down to 0.1 µ-ohm, they are nonetheless designed to be rugged and portable for use at the job site. A variety of optional test leads and calibration resistance standards are offered for use with DLROs.

The MEGGER DLRO10 and DLRO10X bring new standards to low resistance measurement. Both are fully automatic instruments, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1 µ-ohm to 2000 ohms 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. DLRO10X 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 which 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.

The unit is powered from either its rechargeable battery or line power making it suitable for continuous testing in production line/repetitive use environments. Hide (click to hide)

Rotary switch controls are simple and easy to operate in all weather conditions and with gloved hands. A large, clear, backlit LCD display is easy to read from a distance.

The DLRO10HD provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mO and 1A into measurements up to 2.5 O. The duration of each test may be up to 60 seconds.

The DLRO10HD is rated CAT III 300 V. A range of test leads is available to suit the application.

The DLRO10HD provides five test modes each of which is selected through a simple rotary control.

The DLRO200-115 is designed to check and measure contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any low resistance measurement. The test set accurately measure resistances ranging from 0.1µ-ohm to 1 ohm, at high currents. Hide (click to hide)

This versatile instrument can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth dc current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps through a total current loop resistance of 11 milliohms. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker’s control (bus differential relay), if left in the test circuit.
