For everything from routine current measurements to troubleshooting industrial motors and adjustable speed drives (ASDs), three 760 Series meters cover every scenario up to 660AAC. With an exclusive backlit TightSight™ display, the 760 Series brings function and ease-of-use together. The 61-764 is great for basic current measurements, but also has an array of more extensive features like a bold, bright backlit display and selectable auto power off. With added capabilities like True RMS and 40-100Hz frequency measurement, the 61-766 gives electricians a level of certainty when measuring circuits with ASDs. And for those who work with DC motors and circuits, the 61-768 is the right choice.
