Automatic self calibration and diagnosis by user cancels out long term internal drift and verifies functionality
The Alpha-A system includes several levels of user calibration, including open-, short-, load- and fully automated system calibration for the impedance ranges and internal reference capacitors. This compensates for long term drift and ageing.
Returning the analyzer regularly for factory re calibration is not required. During system calibration, all ranges are verified by self test procedures. Deviations or failures are reported.
