In general if the meter is way off it's not a calibration issue. To be clear, calibration is just checking to make sure the meter is within spec. Things either pass or fail calibration. Adjustment is what you do if there is something you need to change to put the meter back in spec. In general, Fluke meters aren't adjustable. I'm not saying they can't be but if the meter is that far off you are looking at a repair, not an adjustment. If you visit the EEVblog with pictures the people there may be able to tell you what is wrong. I've fixed a few meters where the issue was some type of damaged component. This guy has several examples on his blog
Your meter may well be fixable but odds are no one will do it for a reasonable price. At the same time you can get a Fluke 101 for <s>$50</s> $70 (damn the price went up) off ebay or a bit more off Amazon. It's a good equivalent Fluke product. You can also get a Brymen based Greenlee DM-200A off Amazon for $100. The 200A is a really nice basic meter with Fluke levels of safety.
There are a lot of meters I would consider generally better than that Fluke even though I do have a soft spot for Fluke meters.
