A good place to start is by powering the circuit with a bench power supply with a current limit control. Starting with the first component or the one easiest to check, work. Used the two wire testers.
Web Voltage Drops In Series Circuits.
A good place to start is by powering the circuit with a bench power supply with a current limit control. Five techniques in applying the multimeter to aid. Web you should always test the meter before using it to troubleshoot.
Get Rid Of Any Type Of Real Estate On The Tool In Order To Get To The Circuit Card.
Disconnect the electric gadget that the circuit card belongs to. Consider the simple series circuit in figure 13.2. For a voltmeter, test the meter on a known voltage source before using.
Set The Multimeter To The Appropriate Setting For The Sensor Being Tested.
Web using a multimeter for troubleshooting. Check for loose parts or screws inside the multimeter’s case and fix. Web if you do find a damaged connection desolder it with a soldering iron and wick and resolder it.
Web When Measuring Voltage In An Electrical Circuit, Always Touch The Probes To The Circuit’s Terminals Rather Than Across Energized Wires To Avoid Shock Or Injury;
Web test the voltage of an object by placing the red probe on the circuit nearest the positive — incoming — end of the circuit, and place the black probe further down the. This may include selecting the correct voltage range or. Consider just one break at a time:
Web Contact The Multimeter Leads To The Power Source (A Wall Outlet Or Power Cord), Or At The Load (An Element Or Motor).
Web this could be due to a continuity problem — a break in the circuit. Set the voltage to the right amount. Disconnect the common wire (s) from the terminal strip on the controller.
