Resistance decade box 1427

high-precisioncomputer-controlled

HIGH-PRECISION RESISTANCE DECADE - 1427 In its function as temperature simulator the decade offers the choice of sensors like Pt100, Pt200, Pt500, Pt1000, Ni 100 and Ni 1000 in the range from -200 °C up to +850 °C. The temperature is entered via keyboard or data interface. The corresponding resistance appears at the output socket in two, three or four wire method. The resistance decade allows a direct choice of resistances between 1 Ω and 1.2 MΩ. Depending on the ohm value the resolution can be chosen up to 0.00001 Ω. The selected resistance can be picked up via two or four wire method. The LCD display informs about chosen resistance or temperature, sensor type and control status. Features: - Resistance range from 1.00000 Ω to 1.200000 MΩ - Accuracy 0.005 % - Temperature coefficient < 1 ppm/K - Simulation of RTD (Pt, Ni) temperature sensors - Simulation accuracy 0.02 °C - 2, 3, 4 wire connection - USB/RS232 (IEEE488/Ethernet optionally)
