DLRO® DIGITAL LOW RESISTANCE OHMMETERS SINGLE-PAK, BATTERY-OPERATED (10A)
This compact instrument packages measuring circuits, rechargeable batteries and charger in one self-contained unit. Ruggedly built to handle the most demanding field applications, the Single-Pak is housed in a tough Noryl® case with hinged, removable lid and carrying handle.
This model also includes captive wing nuts.
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 µOhms, 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.
Applications
Operation is simple: just connect the leads, turn the instrument on and read the measurement directly from the digital LED display. No warm-up is required.
Typical applications include measuring the resistance of:
* Switch and circuit breaker contacts
* Transformers and generators
* Motor windings
* Busbar and other joints
* Aircraft, rail and pipe bonds
* Cable splices, welds and fuses
* Metal alloys
* Graphite electrodes and other composites
* Wire and cable
General-Purpose DLROs:
This model specially designed for general-purpose testing applications is available. It provide up to 10 amperes of test current for measuring resistances to 60 ohms with 1µOhms resolution and ±0.25% accuracy.
