Built-in 4½-digit DVM monitors a second voltage point on the DUT without an external instrument. Slope control configures rise\/fall rates independently in voltage-slope (VSR) and current-slope (ISR) modes for soft start\/stop. Remote sense (S+\/S−) compensates for IR drop on the test leads. List mode and delayer functions program up to 512 voltage\/current\/time groups, stored to internal Flash or USB.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product-container\"\u003e\n\u003ch2\u003eAcross the Design.
