DA Form 3758: Calibration & Repair Requirements Worksheet

DA Form 3758: Calibration & Repair Requirements Worksheet – DA Form 3758, officially titled the Calibration and Repair Requirements Worksheet, is a critical U.S. Army document used to manage calibration and repair needs for Test, Measurement, and Diagnostic Equipment (TMDE). It ensures equipment accuracy, traceability, and operational readiness across Army units.

This article explains the form’s purpose, when to use it, how to complete it, and where to download the latest version. It is essential reading for Army calibration coordinators, maintenance personnel, and TMDE managers.

What Is DA Form 3758?

DA Form 3758 (updated March 2024) is the official worksheet for documenting calibration and repair requirements for TMDE items not already covered in standard references like TB 43-180.

For use of this form, see TB 750-25; the proponent agency is the U.S. Army Materiel Command (USAMC). It supports the Army’s TMDE Calibration and Repair Support (C&RS) program, helping maintain measurement accuracy for mission-critical equipment.

The form has evolved from the older DA Form 3758-R (December 1996) to the current version, which includes updated fields for modern acquisition, weapon systems, and support capabilities.

Purpose of the Calibration and Repair Requirements Worksheet

The primary purpose of DA Form 3758 is to request official calibration intervals, procedures, repair support levels, and inclusion in the Army’s TMDE database when an item is:

  • New or not listed in TB 43-180
  • Recently acquired or fielded
  • Requiring changes to existing support (add, delete, or modify)

It enables the U.S. Army Test, Measurement, and Diagnostic Equipment Activity (USATA) and supporting organizations like Army TMDE Support Centers (TSCs) or Area Test, Measurement, and Diagnostic Equipment Support Teams (ATSTs) to validate needs and establish standardized support.

Accurate use of this form helps prevent measurement errors that could affect safety, equipment performance, or mission success.

When to Use DA Form 3758?

Use DA Form 3758 in these situations:

  • Submitting requirements for new TMDE not found in TB 43-180
  • Adding a new system code or making changes to existing TMDE support
  • Requesting deletion of obsolete items
  • Documenting items purchased outside Preferred Items List (PIL) or without PEO/PD authorization
  • Providing calibration procedures, OEM manuals, or measurement details (e.g., parameters, range, accuracy)

Units should conduct regular inventories and review property books to identify calibration needs. TB 43-180 serves as the primary reference for listed items.
