    In the past I had a VLS501. As Ralph already stated the automatic function is not that helpful as you may think.
    But here some remarks as I remember them.

    Somewhere on the head there was a insignia clarifying for which paper it was calibrated.

    You can test it's function through printing a stepwedge in grade 5. Expose so that a step somewhere in the middle on the print has a density of D=70-75. Compare with a medium grey card. Without changing the print time, make prints with other grades. The density of the field you set to middle gray, if your head is working al right will be the same in all prints.

    A grade 5 will give a higher precision of your exposion time then lower grades.
