HP Agilent 3456A Digital Multimeter 03456-66540 Board Rev C , Taken out of working 3456A unit.. i did test the unit against few standards and voltages. all were with in spec. how ever taking this sensative equipment apart have prob voided the calibration so any part you buy for this unit will need calibration to bring it to spec.
last 4 pictures are of the actual unit these came out of.
