The EC-Series DC Torque Control System Calibration Procedure explains how to verify, calibrate, and adjust torque output for optimal fastening performance. Learn the four key calibration scenarios, including factory calibration, preset torque certification, on-site verification, and torque transfer to the application, to ensure accurate, repeatable results and process confidence. Designed for a cleanroom environment, the FG-CR cleanroom screwdriver is manufactured using a high-grade, low-outgassing powder coat. The tools feature dynamic wear-resistant internal seals to prevent grease leakage and minimize airborne contamination.

Calibration and Measurement Capability (CMC) is expressed in terms of the measurement parameter, measurement range, expanded uncertainty of measurement and reference standard, method, and/or equipment. The expanded uncertainty of measurement is expressed as the standard uncertainty of the measurement multiplied by a coverage factor of 2 ( k =2), corresponding to a confidence level of approximately 95%. Notes: 1. On-site calibration service is available for this parameter, since on-site conditions are typically more variable than those in the laboratory, larger measurement uncertainties are expected on-site than what is reported on the accredited scope. 2. Unless otherwise specified, the calibration method/procedure utilized by the client was developed internally.
This Scope of Accreditation, version 012, was last updated on: 06 May 2026 and is valid only when accompanied by the Certificate.
