Model 2005 Resistance Master
The Harris IRT Rnterprises Resistance Master - Model 2005 is an excellent portable standard for periodic calibration checks of production resistance testers. It provides a precision, laboratory-quality resistance set in a rugged, lightweight, easy-to-use unit. The possibility of a calibration error occurring due to switch or lead resistance is eliminated by utilizing a true, four-wire Kelvin connection between the panel-mounted banana jack terminals and the internal precision resistors.
Use of the Model 2005 simplifies calibration checks of Harris IRT Enterprises' (and other makes) resistance test equipment. Full-scale measurement of each range of the instrument being tested can be checked directly by simply turning the Resistance Master dial to the full-scale upper-limit value of the range under test.
Two certification levels are available for the Model 2005:
The Model 2005 is accompanied by a certificate certifying the standards comparison.
±0.02% at 25°C.
3" [76mm] wide by 4" deep [102mm] by 6" tall [152mm]
Harris IRT Enterprises resistance test equipment make use of a four-terminal Kelvin measurement system. This eliminates the inaccuracies introduced by test lead and connection resistance. Four leads are required to make measurements: two current leads “I” and two voltage leads “V”. For best accuracy, each voltage and current lead should connect separately to the component under test.
Special test leads have been developed to meet special testing situations:
Each Kelvin test lead set is available separately from Harris IRT Enterprises or as an option with the purchase of a Harris IRT Enterprises Resistance Tester.
