Any and all maintenance must be done IAW some form of approved data. (Are you aware that is in the REG's?)
No disagreement there. Did you know an AMO can generate their own data? Nooo!

You sound like you work for CASA.
Champion suggest a 12-month VOLTAGE calibration, not a pressure gauge calibration. The document is here, page 18.

What I can tell you is that the manufacture of our spark plug tester is getting annoyed with me because I keep pushing the calibration line with them, the response I keep getting back is "The tester does not require calibration".
I will get back to the OP question shortly.
