Standard Programmable Resistor
The SRP-50k0-5T0 calibrator is a source of high resistance, used as a standard in calibration and tests of analog and digital insulation resistance meters.
The set resistance by the calibrator can be maintained for a long time under external direct voltage up to 5000V, provided that the current in the measuring circuit does not exceed 3mA.
The required resistance is set by the user using the calibrator's touch keypad or via an external PC application. The required value is set thanks to the switching of a precise resistance matrix automatically. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.
