is there a trick to measuring ohm with a multimeter?

Question

i have a craftsman 82414 multimeter and i am very unsure about the reading that comes up i have attached a picture of the device as a link below

i am just trying to figure out how to get an exact reading on this thing

i am measuring it on a power supply and which ohm setting should i set it to
(look at the picture)

Answer 1

Hey, it depends on what are all the scales that the multimeter has. Certain multimeters do not provide Ohmic scales but only volt and amp scales. In that case, just connect the multimeter in series to find the current and then connect it in parallel and find the voltage. Then the Ohm's law should help you.

Answer 2

I am not familiar with the meter you are talking about, but I have used quite a few different ones and I have some general pointers.

First, you have to have a rough idea of the resistance the you are testing across. The meter works by putting another resister in parallel with the one you want to measure and getting the resulting voltage across the known resistor to find the resistance across the unknown. So, place your leads on each end of the resistor. You measure this with the resistor out of the circuit or with making sure that there is not another path between the leads.

If you really don't have an idea of the resistance you want to measure, attach the leads and move the dial through the various resistor range settings until the meter gives a reading other than infinity or zero.

Answer 3

Resistance is measured across an element, a resistor. Make sure there is no power in the circuit. You can ruin your mete. If unknown, set the meter to it highest setting. Take measurements and move the setting lower until you get a good, usable reading. Do set the meter below the value of resistance. On a digital meter, it doesn't matter so much. On an analog, you could peg out your meter and possibly damage it.

Answer 4

set the meter to ohms then select the scale that's about how many ohms you expect to read use the range that gives you about a mid scale reading. Turn the power OFF to the equipment you are measuring.put the leads to opposite traces or wire or leads on the circuit you are testing.Many circuits have capacitors in them which give very strange readings at first (0 then max) do to charging of the cap. Some ohm meters will also measure your resistance if your finger or hand is in contact with the circuit or test probes.

Answer 5

Looking at the drawing, you should set the selector at the lower left, green color, OHMS setting.

Range:
->|- (with speaker icon)
200
2000
20K
200K
2000K

The item with the ->|- symbol is for testing connectivity by way of audio feedback (speaker icon). This can be used, I presume to test diodes as well. One way audible and the other way, no sound.

For the resistance 200, it should measure values up to the hundreds. You can try to measure known values of resistance, so that you can verify and get more comfortable with your meter.

Make sure that you are using the correct range setting to measure your resistors. And as previous answers have suggested, there should be no external active current flowing in the resistor to be measured, otherwise, you may end up with an inaccurate reading.

Answer 6

you set your multimeter to measure ohms and test the resistor. the measurement you get will be different than what the color code indicates but is close and is still usable

Answer 7

And the one thing no one mentioned: Put the test leads into the Comm port (center) and the one to the right of it.
