Troubleshooting Technique part 1

To perform a troubleshooting tasks,firstly we must properly an understanding of problem solving and the overall concept of troubleshooting and repairing.It have a step by step technique or method to make a troubleshooting tasks more effective and achieve the target.

From my experience i made an observation about troubleshooting skills at my work placed and i recognized the several mistake done when perform the task.The major mistake always happen is a troubleshooter not analysis or find the root cause of a defect.

For example,when they found the machine cannot operated due to main fuse was blown,they only just change the fuse.They not make a analysis why the fuse is blown.Many reason or cause can make the fuse blown such as overload,short circuit or others.If we found the root cause,we can settle the problem without waste a time and expense for unnecessary matter.

Description Of The Multimeter

What is a multimeter?

Before we know how to use a multimeter,we must understand a safety information about multimeter.

To avoid possible electric shock or personal injury,PLEASE follow these guideline

  • Do not use the meterĀ  or test lead if they appear damage or not operating properly.
  • Always use proper terminal,switch position and range for measurements.
  • Verify the meter`s operation by measuring a known voltage.
  • Do not apply more than the rated voltage,between terminals or any terminal and earth ground.
  • Use caution with voltage above 30 VAC rms,42 VAC peak or 60 VDC.It pose a shock hazard.
  • Disconnect circuit power supply and discharge all high-voltage capacitor before testing RESISTANCE,CONTINUITY,DIODE OR CAPACITANCE.
  • Do not use the meter around explosive gas and vapor
  • When using test lead,keep your finger behind the finger guard.
  • Avoid working alone
  • Use only the replacement fuse specified.
  • Check the test leadĀ  for continuity before use.Do not use if the reading are high or noisy. read more
