The 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.
STANDARD FEATURES
Electrical features include linearized analog output of 0.1 mV per count, which is ideal for driving a strip-chart recorder. Mechanical features include a bright 14 mm (0.56") LED display, a screw-terminal barrier strip for signal and power, and a compact 1/8 DIN case that requires a depth of less than 104 mm (4.1") behind the bezel.
OPTIONS
Power options include isolated 9 to 32 Vdc and 26 to 56 Vdc. Other options are a PCB edge connector for display control and output of +4.7 Vdc and -4.7 Vdc, and a splash-proof lens cover which meets NEMA 4(IP65) requirements.
