Real effective amps clampReal-effective measurements and optimized ergonomics make the 320 series clamp-on ammeters the most important for installation and troubleshooting in industrial and building technology applications. The Fluke 323, 324 and 325 Clamp Meters are used to check circuits, switches, fuses and contacts for the presence of load current, AC voltage or continuity. These compact and robust clamp-on ammeters are Ideal suitable for current measuring up to 400 A in cramped switch cabinets. The Fluke 325 clamp-on ammeter also enables direct current and frequency measurement.TL175 TwistGuard leads setSilicone measurement leads set of the special kind: In order to meet the requirements of EN 61010-031 safety classifications, the over-voltage category can be set between CAT II 1000 V and CAT III 1000 V/CAT IV 600 V because of the rotating measurement tip adjustment. Moreover, damages become visible immediately owing to the second white silicone layer. Design with 2 mm thin measu
