Programmable calibrator SRP-50k0-100G0

voltageresistancefor insulation tester

The SRP-50k0-100G0 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 2500 V, provided that the current in the measuring circuit does not exceed 1,5 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. Features Standard programmable resistor is a source of high resistances used as standard equipment for calibration and testing of analog and digital insulation resistance meters. The resistance obtained thanks to this resistor can be kept for a long time under external direct voltage up to 2500 V under the condition that current in the measurement circuit does not exceed the value of 1,5 mA. The required resistance is set by the user by means of the standard resistor’s keypad and external PC application SRP Control Software. Setting of the required value is automatic thanks to commutation of a precision resistance matrix. The control processor calculates the required combination of resistors providing the proper precision of the resultant resistance.
