General: As a matter of principle, all power supplies must be calibrated regularly.

> **Note**
> IRS Systementwicklung GmbH recommends annual calibration. The calibration intervals and calibration procedures must be defined and organized by the customer. To avoid downtime of the test system, the customer must keep spare parts available, in accordance with the defined calibration procedure, that can be exchanged temporarily. Calibration contracts with the manufacturer must be negotiated with the manufacturer independently of the purchase of a test system.
