FLUKE 5100B calibration failure help

[Louis_C]

I need some help adjusting a Fluke 5100B. I had to run a calibration on our unit yesterday to keep it up to date. Well, it failed on two points AC and DC high voltage. The spec for the DC at 1000v is LOWER LIMIT = -1000.0600 and UPPER LIMIT = -999.9400. Unit failed at -1000.1741. AC LOWER LIMIT = 699.601. AC UPPER LIMIT = 700.400. Unit failed at 698.211. Where do I adjust the unit to correct these voltages? Thank you in advance. Lou.
