EZ-TorQ III Torque Analyzer – FAQ & User Guide

Quick Answer

The EZ-TorQ III Torque Analyzer is used to verify tool performance, validate calibration status, and measure torque values for hand tools and non-impacting power tools. It provides a portable solution for calibration labs, assembly stations, and production environments.

Who This Is For

Quality engineers and quality assurance teams
Calibration technicians and metrology labs
Manufacturing and process engineers
Production supervisors and assembly teams
Companies implementing torque verification programs
Facilities performing in-house tool calibration and validation
Aerospace, automotive, electronics, medical device, and industrial manufacturers

When Should You Use This?

Use the EZ-TorQ III when:

Torque tools require routine verification or calibration
Daily, weekly, or monthly tool validation is performed
Quality standards require documented torque verification
Tool performance needs to be checked directly on the assembly line
Torque data collection is important
You want to reduce calibration turnaround times
In-house torque testing is part of your quality program

When Should You NOT Use This?

Do not use the EZ-TorQ III when:

External torque sensors are required
A broader torque range is needed than a single analyzer model provides

Choosing the Right EZ-TorQ III

When selecting an EZ-TorQ III analyzer, consider:

The normal operating torque of the tools being tested
The required measurement resolution
Whether you'll primarily test hand tools or non-impacting power tools
The type of run-down adapter needed for hard- or soft-joint testing
Whether portability and on-the-floor verification are priorities

Selecting an analyzer with a measurement range that closely matches your application provides the best accuracy and resolution for torque verification.

Setup & Adjustment

Before using the EZ-TorQ III:

Charge the analyzer using the supplied power adapter.
Install the appropriate run-down adapter for the tool and application being tested.
Select the desired operating mode and measurement units.
Connect the torque tool to the analyzer.
