Analog Meter for Snap Circuits.
* The meter has + and - polarity marking to indicate which direction the current will move the pointer. It also has a switch to change between low and high current scales (marked as LOW-HIGH or 10ma-1A)
* The meter will measure the current when connected in series in a circuit. By itself, it can measure currents up to 300uA in the LOW setting and up to 1A in the HIGH setting, but higher currents may be measured by connecting a low value resistor in parallel.
* The meter will measure voltage when connected in parallel with a circuit. By itself, it can measure voltages up to 0.3V in either switch setting, but higher voltages may be measured by connecting a high value resistor in series with it.
