About operation(using) of multimeter?

Question

Dear friends ,

anybody can help me?With the help of, multimeter

1.How can i check continuity of a circut.

2.How can I check a resistent or cupasiter or resiter its value and good in condition.

Answer 1

set the dial to the ohms (upside down U) position, and touch the probes together - the meter will say 0 - this means you have a continuos circuit.  If there is a resistance between the two, it'll say how much.

     1 - always have circuit unpowered, using ohms range

     2 - when using amps range, never connect accross power supply, - must be inline with circuit

      3- your first meter should be real cheap. you'll make mistakes 1&2 & end up with only the volts range working

      4 - never let anyone borrow your meter , let them ruin their own meter learning how to use one.

I won't even borrow mine to people who know how.

       you can also test for continuity with the volts scale - if current is flowing THRU, there will be a voltage ACROSS each part.

      -resistors  resist AC or DC current

      - capacitors  mostly block DC, resist  AC current

      - coils mostly block AC, resist DC

      - three terminal devices (transistors & ?)are like kind of like a resistor, third wire controls how much resistance

     I asked an electrician a similar question one time, he had a good answer " you're going to have to hit the books"

Answer 2

Google your question and you will get a list of many web sites with the answer.
