Phobia In Voltage Testing

By on March 13, 2010

I’d heard some stories about technicians that have phohia problem especially in voltage testing. The reason why they had this problem was because they may had been accidentally shorted some of the testing points in the electronic circuits. The spark generated by the big filter cap or the electronic circuit section totally blown that had caused them not bold enough to perform voltage testing again. For your information, voltage testing can solve lots of electronic problems fast and if you did not use this method of troubleshooting, you may have a hard time in locating fault.

Now in order for you to gain back the confident of voltage testing, i suggest that you play around with electronic project kits first that use low DC voltage. Once you are good in pinpointing fault in DC circuit then only you move on to AC circuit. Your other option would be to get someone that you know to help you in this area. If you need to pay then just pay him to learn about the voltage testing.  Once you are good in voltage testing there is no limit of electronic circuits that you can test thus finding fault faster than any other method.

    I used to be afraid to do the voltage testing because I did not know what to do therefore causing something to blow. Now, thanks God I am way beyond that point and I am doing my own voltage testing. one important thing I have learnd in voltage testing, when doing the voltage testing you can not be distracted or have something on your need complete attention other wise you will lose the focus and blow up something.

    i recommend isolation transformer for all technician wants to ck AC
    in circuit . this guarantee your health during the test the faulty sets
    and decrease panic level of voltage checking
    jestine am i right?

    HI Beh,

    Yes it can save our live too of not exposing directly to the live ac.

    HI Waleed,

    Your are right the keyword is "focus" when doing the voltage testing.
