  1. yea, eventually the page did open, clicked on one of the links and …………………….

    opened the link

    I will check back later

  2. @Kattayil: I don’t think you completely get the point. The “suggested” Resistance, DC and AC references have no relation with atomic clocks and/or frequency refrences.

    Moreover “CW radio freq. ref.” idea is simply impractical.

  3. Dite, did you even read the site? It clearly says these are cheap and easy ways to get pretty good calibration for hobbyist tools.

    If you can afford professional calibration you are not a hobbyist.

    Having a rock for a weight standard is fine, but other than relative measurement in a laboratory balance (Item measured is greater than or less than the mass of “Rock”)To what degree of precision and accuracy do you calibrate against your rock standard?

    e.g. Item = 0.9753 Rock

    How is Rock associated to other standards such as second, resistance, volume, farad, henry, volt?

    0.736802 seconds = length of time required for said rock to fall from hand to big toe. Physical constant.

    Owwwm = measure of resistance in picking up said rock. Substantiated through MRI observation according to the following: 3.713 Owwwm/slipped disk.

    91 dB = sound pressure level of vocalization of 3.713 owwwms. Also note that a free fall of 0.736802 seconds to big toe will result in an SPL of 86 dB at 2.015 owwwms.

    1 Farad = 1 second/owwwm. Perceived length of ambulence ride to hospital for aforementioned MRI = 1.0E6 Farad*owwwms.

    3 Henries = number of friends needed to assist in lifting rock for a individual equivalent resistance of 0 owwwms.

    1.0 Volt…sorry, I work 3rd shift. I’m going to bed :)
