PRECISION RESISTANCE DECADE SIMULATOR
OCM 622
This is a high accuracy and high stability resistance decade. It is designed as a temperature simulator as decade. In the temperature mode the instrument simulates RTD Sensors within a range from -200 C to +850 C. Thermometers Pt-100, Pt-200, Pt-500, Pt-1000, Ni-100 and Ni-1000 can be selected. The required temperature value is entered with the keyboard or via the data port. The corresponding resistance is the data port. The corresponding resistance in a available at 2, 3 or 4 wire output terminals. In the variable resistance mode the instrument permits a direct selection of resistance in a range from 1 0hm to 1.2 MOhm. The resolution depends on the resistance value selected. The resolution depends on the resistance value selected. The highest resolution is 0.000010hm. The selected resistor is available at 2 or 4 wire output terminals. A Soft Manager for Windows at a diskette is suitable the communication via RS232 or IEEE488 Data Bus. It permits the selection of the resistance from a PC or from a supervising controller. An LCD displays informs about the selected parameters and the control status.
