Description
Testo 770-1 - Hook-Clamp Digital Multimeter with TRMS Inrush
The testo 770 Hook-clamp Digital Multimeter (DMM) is ideally suited for electrical work in HVAC applications. Testo s unique hooking clamp can be used to separate then grab wires. The easy hook-off retractable post releases the wires when testing is complete. You can safely work in tight spaces without using your hands.
Features:
- Unique hook-on function separates and grabs wires without using your hands
- Retractable post makes hook release fast and easy
- Meter automatically identifies testing in-process and selects correct meter configuration to save time and optimize accuracy
- Inrush (starting) current capture, APO (Auto Power Off, and Min/Max/Hold)
Overview
The 770 series identifies the testing in-process and automatically selects the correct meter configuration which saves you time and increases your accuracy.
The 770 series of instruments are rich in the features HVAC techs need and want including TRMS, starting current, and frequency measurement.
