- Typical industry practice is every 12 months for test equipment used in a quality-controlled environment. Some labs may extend to 24 months with supporting stability data and in-tolerance history. Calibrate after any repair, significant shock/transport, or if the instrument fails verification checks. The timebase (in the mainframe or external reference) is the dominant factor; if precision timing/frequency accuracy is critical, maintain an annual calibration or verify the timebase more frequently against a known standard.
