ValueTronics 247000 毫欧表

"The 247000 is a dlro from Megger.","Additional Features:","Accessories:","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:","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 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."
