OK. You are building up an I/PM (Inspection and Preventive Maintenance) Procedures Manual.
Proper PM should include calibration if and when necessary (it should also include electrical safety testing).
There have been collections of "procedures" available on the internet from various sources (mainly biomed groups in the U.S.). I have looked at some in the past, and a few were OK. So you could try looking on line (remembering, of course, that "Google is your friend"). But I believe it is far better to develop you own procedures in-house, in order that they reflect your particular circumstances and requirements.
But you need to take things slowly (one equipment type at a time). You can write up your procedure (and subsequently improve upon it) each time you visit the equipment for PM. Eventually you will get through them all.
You also need the (technical service) manuals. Does the outsource company have these?
How supportive is the senior management at your hospital ... or, has all this just been dumped on you (for whatever reason:- the present situation costing them too much, for example)?

Have you taken your inventory yet? That is, do you know what equipment you shall be maintaining?
If all else fails, just come on here for a new procedure every day! But it would be far easier (for us) if you presented your
own (draft) procedure, in each case, for us to comment on!
