This might be a basic question, but I was thinking of getting some analog panel meters for a project. Most of them are calibrated with volts or amps, ac or dc. Like 300 V DC full scale or 10 Amps full scale. Does this mean that the required shunts or voltage dividers are INSIDE the meter? Or would external components be required to achieve the full scale printed on the meter face? I realize the basic meter movement would be 50uA or 1mA full scale (for example). I couldn't find any clear information on this either way.
Also. Has anyone bought analog meters from ebay? I see some really cheap ones from China. Are they any good quality wise? Some others, like the older Weston or GE look nice.
Thanks.
