Measuring Voltage Measuring Voltage – connect meter directly across the component EGR 101
Measuring Current Measuring Current – insert the ammeter in the current path YOU MUST BREAK THE CONNECTION! EGR 101
Measuring Resistance • Should not be measured with power applied to the circuit • Best to disconnect one end of the resistor before measuring EGR 101
