The LOM-530 calibration kit is designed for the IET Lom-510A which has the equipment and features to measure very low resistors accurately, simply and economically.

Four measurement methods are available with the Lom-510A: Switched DC, Constant DC, Pulsed Mode and Dry Circuit. The measuring range runs from 1 µΩ to 200 Ω. The instrument has a 4½ digit display, 0.02 % basic accuracy and 1 µΩ resolution. The four-wire resistance measurement eliminates measurement errors caused by cabling and 80 dB AC noise reduction ensures rock-solid readings even in disturbance-prone environments. A variety of different probes and clips are available to measure any unknown low resistance.
