Megger DLRO24700 [247002-11] Digital Low Resistance Ohmmeter 10A w/ Input Voltage Protection

The Megger 247002-11 Digital Low Resistance Ohmmeter is a highly accurate instrument that provides a simple, practical and reliable means of making low-resistance tests in the field. It is also are ideal for production quality control.

The 247002 Ohmmeter operates on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of +/- 0.25% and resolution down to 0.1 microohms, the ohmmeter is 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 the 247002.

The 247002 is a compact instrument that packages measuring circuits, rechargeable batteries and charger in one self-contained unit. The 247002 furthermore provides an extra range, 0 to 599.9 microohms, for applications requiring 0.1 microohm resolution. It also features a current-reversing switch to average out any voltage offset in the test sample.

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.

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. The 247002 also includes captive wing nuts.

Input Voltage Protection
To protect the instrument when testing battery straps, this option (included with the 247002-11) provides input protection against accidental overvoltage up to 30 volts. This option, however, is not suitable for when the instrument will be used to test transformers and other inductive components.
