a. Deenergize and discharge the circuit completely before  connecting or disconnecting a multimeter.  
 b. Never apply power to the circuit while measuring  resistance with a multimeter.  
 c. Connect the multimeter in series with the circuit for  current measurements, and in parallel for voltage measurements.   d. Be certain the multimeter is switched to ac before  attempting to measure ac circuits.  
 e. Observe proper dc polarity when measuring dc.   f. When you are finished with a multimeter, switch it to the  OFF position, if available. If there is no OFF position, switch the  multimeter to the highest ac voltage position.  
 g. Always start with the highest voltage or current range.   h. Select a final range that allows a reading near the middle  of the scale.  
 i. Adjust the "0 ohms" reading after changing resistance  ranges and before making a resistance measurement.   j. Be certain to read ac measurements on the ac scale of a  multimeter.  
 k. Observe the general safety precautions for electrical and
