Already during the development of our products we pay attention to robust and durable parts and electronic components, which are accordingly rugged and fail-safe. Our quality assurance in production is constantly being expanded and continuously improved in accordance with our DIN EN ISO 9001 certification.
“Built-In” by Default: The Factory Calibration
Calibration is an integral part of our manufacturing process. No electronic load leaves our factory without being calibrated carefully and appropriately for the respective purpose – regardless of whether it is a series product or a special solution made to customer order. With each electronic load or 4-quadrant power supply we deliver a Factory Calibration Certificate (FCC).
The calibration process is subject to supervision in accordance with DIN EN ISO 9001. The FCC documents the traceability to national standards for the representation of physical units in accordance with the International System of Units (SI).
For use under laboratory conditions, H&H recommends a calibration interval of 2 years. This is an empirical value that can be used as a guide for the first period of use. Depending on the intended use, service life, relevance of the application and ambient conditions, the operator should adjust this interval accordingly.
In order to keep the lead time for a calibration as short as possible, we recommend that you make an appointment with our service department early on. Please request an RMA number to return the instrument for calibration.
Free Recalibration Within 2 Years
Each factory calibration certificate delivered with the instrument contains the commitment that the instrument will be recalibrated free of charge once within the warranty period. Our customers can send the device to us for this purpose. The recalibration is carried out directly at our premises.
Calibration “On Demand”
Of course, we also recalibrate at any time if required by the application or by customer request – e.g. in the course of regular inspections.
