DescriptionThe DP3002-O is a low-cost, high-resolution 4-1/2 digit (19,999-count) resistance meter with readout directly in ohms. Four ranges are jumper-selectable: 19.999 Ω, 199.99 Ω, 1.9999 kΩ, 19.999 kΩ. It is complete with low-level current excitation and open-resistance indication. The current source is tied to the reference of the A/D converter for true ratiometric operation and immunity to changes in line voltage.
