Special Features
The model sr-90 is a two-peice test set is designed so the main controlsectio (unit 1)& the auxillary section(unit 2) can be used independently from each other for testing simple peotective divices. To perform testing of more complex relays, unit 1 & unit 2 areeasliy interconnected to provide four simultaneous outputs of ac current & voltage, & dc current & voltage; operating temp. Is 0 to 55c, storage temp. Is-20 to 70c; standard accessories provided are interconnect cables, input power cables, ground lead, test leads, fuses, instruction manual & carrying case for accessories; test set can be rack mounted in a standard 19 inch rack or bench top
