    Can anybody tell me what's the difference for calibration as follow.

    1-point deluxe NIST Calibration
    3-Point deluxe NIST Calibration
    3-point ultima deluxe A2LA NIST

    That's calibration servies company stating options on the certificate. I
    don't know the difference but price. I only need the one fullfill
    Regulation requirement at minumum cost.
