The model 291 uses a parallel electrode configuration conforming to ASTM D-257. It also accepts external electrodes for point-to-point and resistance-to-ground measurements. A test lead is included for resistance-to-ground measurements. Model 291 is convenient and easy to use. Simply place the 291 directly on the item to be measured. An easy-to-read, color-coded LED decade display quickly and clearly indicates the resistivity or resistance range.
