SONEL Standard Programmable Resistor SRP-50k0-5T0

The SRP-50k0 - 5T0 calibrator is a source of high resistance, used as a standard in calibration and tests of analogue and digital insulation resistance meters.

The setted resistance by the calibrator can be maintained for a long time under external direct voltage up to 5000 V, provided that the current in the measuring circuit does not exceed 3 mA.

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 automatically thanks to the switching of a precise resistance matrix. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.
