calibration/adjustment procedure for CEM DT-9939 /EXtech EX540 /Digitech QM1575

[MacGyver0606]

Hi, I'm looking for the calibration/adjustment procedure for any of these Multimeters, which are pretty much the same. I couldn't find it anywhere. Any help??

CEM DT-9939/DT-9929 (original manufacturer)
EXtech EX540/EX530 (Americas/Europe)
Digitech/Jaycar QM1575 (Australia)
Hikari HM2920/2900 (Brazil)

You can usually get calibration procedures for Extech instruments from Extech support, takes them a couple of days to respond:-
