No battery in the 3456A. Calibration is by knob twiddling.

Does anyone know
about the HP 3456A DMM? I can¡¯t remember if it requires a battery for cal
memory or not.
Thanks

The 859X series
spectrum analyzers loose: band leveling offsets, attenuator corrections, and
clock corrections if the memory battery dies. There is at least a procedure to
copy these down from the operator interface so they can be reloaded in event
of failure.?

Hello
David?I think the HP 8756 Scalar analyzer?Looses all the Channel
calibration data if the battery is lost. This requires?programming
through a HP computer with obsolete software.

2) HP 3457A 6.5
digit multimeter
whilst not so
catastrophic, a report I read recently on one of the newsgroups from someone,
said he sent a 3457A in for calibration, and the company was not happy as the
failure of the battery added an hour to the calibration time. They were going
to charge for this, but in the end they did
not.
Just to clarify,
the extra hour was not for replacing the battery - the owner had already done
that. The extra hour was for the fact every range needed zeroing and setting
to full scale.?
