    Measuring the flow of electric driven present in a circuit is one of the rudimentary checks presented when troubleshooting a malfunctioning agency circuit or electric appliance. Knowing the allowance of present drawn by an electric burden will expedite isolating the origin of electric problems. There are two modes of assessing the present raging torrent in a circuit. You can bodily attach a accepted ammeter in sequence (in line) with one of the current-carrying conductors, or you can use a clamp-on meter which has jaws that break round the current-carrying conductor.
   
   General Instructions
   
   • Access the electric wiring that provision the burden for which you are assessing the present draw. A burden is any thing that spends electric power, for example a lightweight bulb, apparel dryer or cleaning machine. Depending on the burden, you may require to eliminate a junction carton cover, a sheet-metal section or some other cover. After profiting get access to to the wiring, mindfully distinct the current-carrying wires providing present to the load. The current-carrying wires providing a 110 volt burden will be a very dark and a white wires. The wires providing a 240 volt burden are a red and a very dark insulated wires.
   
   • Turn the clamp-on multimeter power swap to the on position. Set the clamp-on multimeter function swap to its amperes position. Squeeze the lever, unfastening the clamp-on multimeter's movable jaw. Slip the open jaw over one of the current-carrying wires and issue the lever, concluding the jaws round the wire. In alignment to confirm you get an unquestionable reading, make certain that you have only one of the current-carrying wires interior the jaws.
   
   • Turn on the burden being checked and read the allowance of present drawn by the burden on the fluid crystal brandish on the meter. The 120/240 volt line voltages discovered in your dwelling are nominal voltages. Nominal voltages may alter by in addition to or minus 10 per hundred and still be acceptable. If the burden present drawn declines inside 10 per hundred of that present marked on the burdens title plate, it is OK.
   
   Using the 3-prong Line Splitter
   
   • Plug the 3-prong line splitter into any 120-volt receptacle. Plug the cord of any plug-connected burden (vacuum cleaner, coffee manufacturer or other little appliance) into the receptacle on the 3-prong line splitter. The line splitter assists to distinct the two current-carrying conductors interior the appliance cord. Without the splitter, you would have to slit the cords outside covering to distinct the conductors.
   
   • Set up the digital clamp-on multimeter as you did in Section 1.
   
   • Snap the clamp-on meter's jaws through one of line splitters openings and take the reading. The identical percentages as granted overhead request to these readings.
