HP 3478A Multimeter

Send it out to a meteorology lab. You would need a few calibration standards to even get close to doing the job.

Possibly proprietary information from HP. You could check with a metrology (not "meteorology") laboratory. True calibration is a recurring requirement specified by the manufacturer.
You will need laboratory standards, as Tallman said. And they, too, have to be properly and currently calibrated in order for you to calibrate your 3478A.

The strange issue is when I bought it didn't require calibration I turned it on last night and kept saying uncalibrated, do these meters have some type of experation .
There ya go. A bona fide calibration by a certified cal facility will include replacing such things as batteries as part of the charge. ...short pause for laughter...
Now, if an instrument requires repair - like if the battery were to leak and get electrolyte all over the circuit board - THAT will cost extra.
How much?
I don't need anymore test equipment. I know that question would be asked.

If somebody is doing repair work and they don't have a laboratory grade VOM this would be perfect for them.
