4-1/2数字欧姆表，1/8 DIN DP3002-O 1年保修 CE 4-1/2数字欧姆表，1/8 DIN DP3002-O:4-1/2数字欧姆表，1/8 DIN DP3002-OR1 19,999 Count Display Span 19.999 Ω to 19.999 kΩ Ranges 2-, 3- or 4-Wire Connection 120 dB CMR, 70 dB NMR 0.1 mV/ Count Linearized Analog Output Bright, 14 mm (0.56") LED Display Display Hold and Test 115/230 Vac Power EMI/RFI Filter for AC Power Screw-Terminal Barrier Strip Short 104 mm (4.1") Deep 1/8 DIN Case Options Serial BCD Output Isolated 9 to 32 Vdc or 26 to 56 Vdc Power NEMA 4 (IP65) Splash-Proof Lens Cover 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.
