Quick answer Display: 4000 counts, updating three times per second, per Fluke’s datasheet. What the 17B+ adds: the datasheet attributes a temperature probe, overload protection and an over-voltage indicator to the 17B+, and not to the 15B+. Safety: IEC 61010-1 and IEC 61010-2-030, CAT III 600 V, Pollution Degree 2. The datasheet also lists a…
