They ARE feedback halls :-) Their specs are pretty hard to read however. The 6A is the "nominal range", but the "measurement range" is three times larger (limited by the output voltage). They have other models with larger nominal current and correspondingly higher range. The measurement errors are static and can be calibrated out, the major one I found is stray magnetic fields. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
