The SRP-10G0-10T0 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 10 000 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.
