Device test data: Ia = 120.0mA range, GOOD A1 78 / A2 79.

We test our rectifiers using a calibrated and standardised AVO VCM163 on the specified range. This VCM gives a qualitative estimation of emission as you can see from the photo, the GOOD range bar runs below the numerical uA/Ig scale with the GOOD range between 51 - 100. The above device test data, shows the max current range specified and a record of the numerical reading within the GOOD range on our VCM163
