Traded for an HP 3456A. Stuck buttons making the display read crazy. Before I started pressing buttons, the display looked normal, so there is hope that there isn't much wrong with this. I need to take apart the front panel to clean and repair all the switches. I'm suffering thorough the flu, so I don't feel like doing too much right now.
The 3456A is quite deep, so finding a place for it will be a challenge. However, it will be nice to have another 6.5 digit meter to compare with my 3457A which was recently calibrated.
