The HP 3456A is a rack-mountable digital multimeter (DMM). Our HP 3456A is owned by a Hacksburg member but has no restrictions on use.

This a 6.5 digit meter; which means that there are six working digits of resolution (although the last one may jump around a bit). This is much more accurate than a typical handheld meter. Note that our HP 3456A has not been calibrated in a long time and may not be correct.
