The DP302-O is a low-cost 3-1/2 digit (1999-count) resistance meter with readout directly in ohms. Four ranges are jumper-able: 19.99 Ω, 199.9 Ω, 1.999 kΩ, 19.99 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 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.

OPTI***
Opti*** are isolated 9 to 32 Vdc or 26 to 56 Vdc power, 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.
