- Typical interval: 12 months (annual). Many labs use a 1‑year calibration cycle for legacy bench voltmeters. If it’s used as a transfer standard or in a critical quality system, consider 6–12 months based on historical stability and risk. Always follow your organization’s quality plan and any applicable standards.

Keysight (Agilent/Hp) 3400B Calibration
