Default Reviving Test Equipment After A Long Storage Period

I have a number of pieces of test equipment (HP, Tek, Fluke...digital/
analog/RF) that have been sitting in storage for a decade.

Time to apply the power and see if they work.

What is the recommended procedure to bring test equipment that has
been stored for a long period?

Also is there a MIL document that relates to this subject?

Thanks for what info you can offer.

Old tube-based items should be brought up with a variac to 80-90%
full voltage for up to a half an hour, and then up to full voltage if no
smoke..
This allows the electrolytics to re-form; rare baddies will complain
(smoke or explode).
Battery powered equipment should have no problems unless the
batteries are a part of an inverter to provide 120VAC..then try to
bypass the inverter and use the variac scheme.
