The Megger 247002 DLRO micro-ohmmeter 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 accuracy of ±0.25% and resolution down to 0.1 μΩ, 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.
This model provides an extra range, 0 to 599.9 μΩ, for applications requiring 0.1 μΩ resolution. It also features a current-reversing switch to average out any voltage offset in the test sample. Captive wing nuts are also standard.
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.
Please consider these optional accessories.
