For educational purposes I try to simulate a ammeter for reading practice.

I would like create six or more ammeter with different readings, but i'm not able to do that because metapost create the same random number every time I call the buffer that defines my ammeter.

How can I fix that?

Is there a reason why you use \externalfigure because the width can be set with \scale, e.g.

    \scale[width=8cm]{\getbuffer[ammeter]}
