Product Description

Overview

The function and range settings are always correct because the measurement parameters are detected and set automatically. Three easy-to-read buttons replace the traditional rotary switch when selecting manual test functions. The 770 series of instruments are rich in the features HVAC techs need and want including TRMS, starting current, and frequency measurement.

Key Features

  • Unique hook-on function separates and grabs wires without using your hands
  • Retractable post makes hook release fast and easy
  • Automatically identifies testing in-process and selects correct meter configuration
  • Inrush (starting) current capture, APO (Auto Power Off, and Min/Max/Hold)
  • Includes μA for flame rod and can measure temperature using Type K thermocouple adapter
