How do i check ohms on coax tv cable


That is not something that you can do to specification. The resistance of that wire is actually the impedance. You are going to only be checking for continuity by setting a meter to the ohm setting and then either short one end against itself and check the other end or use both ends and put one probe on the collar and one on the center conductor. The meter should swing all the way to the right.

How do I check a thermal fuse and heater with a digital multimeter on my Samsung rb215lash refrigerator?


Hello Sylvia;

My name is Peter. I am a retired field service technician.


You need to unplug the sensor. Place the bulb in a glass of ice water. After 10 minutes, Set you multi-meter to the lowest Ohms (Omega Symbol), touch the meter leads together you should get a reading of '1.0' or 'OL' the connector has two plugin ports, with one meter probe on the one port and the other probe in the other port, you should get a reading of 16 Ohms.

You have three sensors, one for the freezer, one for the evaporator coil and one for the freezer:

25316535-e0goqiu2jemxlrpk4czrq0zz-3-8.jpg

You have two defrost heaters they are part of the drain assemblies: Once again, set your meter on the lowest Ohms. Put one contact in one connector port and the other lead in the other connector port, If you get a reading of '0' or infinity the heater is bad. If it is good you should get some reading 25 to 150 Ohms.

All of these components are behind the back fresh food section and freezer wall.

I am sorry you bought a Samsung. 65% of all of my service calls were either Samsung or LG.

Stator replacement


Hi Anonymous, you will need a multimeter, first set it ohms on its lowest setting and touch the two meter leads together to calibrate the setting, then unplug the wiring harnes that goes to the stator. Touch one lead of the meter to one of the stator pins and the other lead to ground on the bike, meter should read infinity. Repeat the process with the other stator pin, reading should be infinity. Attach both leads to the stator pins and you should get a reading of 0.1 to 0.3 ohms. Next set the multimeter to the 100 volts AC range and hook the leads up to the stator connector pins. Fire up the bike and read the meter for every 1,000 RPM it should read 16 to 20 volts AC. If every thing checks out stator is fine. Set the meter to the 20 or more DC volts range and hook it up to the battery, voltage at 3,600 RPM should be 14.3 to 14.7 volts DC if not your voltage regulator is bad. And finally when ever you do any type of electrical diagnostics make sure you have a fully charged battery and all wiring and connections in the circuit you are testing are clean and tight. Good luck

No woofer sound from my K3000FX. Verified all cables and settings correct- but sound only comes from tweeter. What could it be?


Step 1:

Hate to say it, but possibly a blown speaker. To check this, do the following -


Step 2:

Insert headphones into jack to verify for sound there.

Step 3:

Unplug unit and open rear panel to reveal speakers.

Step 4:

Remove leads from woofer.

Step 5:

Using a multimeter, set to OHM (horseshoe) to lowest setting.

Step 6:

Apply red(+) and black(-) to speaker leads. Meter should read at least 4-8 ohms of resistance.

Step 7:

If no reading, then voice coil is blown.

Step 8:

If no meter available to use, the use a 9 volt battery by applying direct connection to speaker leads in an off-and-on fashion - You should hear a "click" sound come from speaker. If no "click," then speaker is blown.

Step 9:

If click is heard, and resistance on meter is correct, then the amp circuitry leading to the woofer may be blown = repair needed.

My dryer had a 4 prong plug, and I moved into an apt and the outlet is 3 prong I changed the plug to 3 prong and now my dryer doesnt work


I would start at the breaker (which I'm sure you 've already checked). Then if you haven't already, I would check the voltage at the outlet. For this you'll need an anolog voltohm meter or a digital multimeter. You can get the anolog version for under 20 dollars. I would go with it if you choose to do this, especially if you're not going to be using it a lot.
Dont worry if you've never used one, because I can tell you how to do it.
First take a look at the dryer outlet. You'll want to make sure it's getting the proper voltage. You should have an "L" shaped slot. That one is neutral. The other two should be rectangular shaped. Those two are the "hot." This configuration is the most common.
If you do choose to get a meter, all you have to do is set the dial to the right place, and read the display. It should have a red test lead and a black test lead. If your dryer is an electric dryer, you'll be measuring for 240 volts AC. On the meter you want to set the dial to the next highest number above 240 (probably 250). here's what to do:
1. Insert a test lead into each rectangular slot. You should get a reading around 240 volts.
2. Insert one of the test leads into a rectangular slot, the other into the "L" shaped slot. This time you'll want your meter a step above 120 volts AC. The next highest number. Take the reading, you should get around 120 volts.
3. Next do the same thing as number 2, just on the other side. (rectangle slot to neutral L shaped slot). You should also get around 120 volts.

If..... You dont get a reading for the 240 volts on the first test, you'll know that you're not getting power at the outlet.
Also, if one of the "sides" for the 120 volts shows 0 or a number thats really low, then one of the legs of the circuit breaker is tripped. When you check the circuit breaker, make sure that you turn both of them off, and then on again. You see, it uses two breakers (or fuses) that supply 120 volts to both sides of the plug, thus giving the dryer 240 volts of electricity.

Also make sure that when you hooked the 3 wires up to your dryer, that you placed the metal strip at the metal terminal and secured it with your middle wire, at the middle terminal.

You could also remove the cord and do a continuity test on it to make sure that it's not the problem. On your meter, you can use the ohms setting, set on the lowest one. wrightly.jpg
Just like this. It's usually RX1, or RX1K. If you look up at the upper left hand corner of the meter, you'll see the ohms sign. Some have a thumbwheel, that when you first turn it on, you touch the two meter leads together, if it doesnt go to 0, you use that wheel to adjust it to zero.
You can also see on the upper right hand side, the AC portion of the voltage test. You would use the 250 setting on this one to do all of the tests above.

I hope this helps you. I will be more than happy to help if you need any further assistance.
Thanks for your time,

Mike

I'm a novice at using a multi-meter but want to check my volkswagon beatle for a short, one circuit at a time. After battery is charged up, it goes dead after a few weeks. Worse in colder temperatures....


you would be measuring current
you would set the meter to maximum current setting
Then place the leads between the terminals of the fuse for each circuit. with the fuse removed.
so if you have a ten amp fuse you would expect a current either below 10Amp or at 10 amp.
maximum setting of current is in case short circuit to ground causes a huge current drain. To prevent blowing up amp meter of multimeter.
You may wish to put a fuse on the lead of the multimeter to safe guard your meter from blowing up in case you encounter a high current it can't handle.
if via the battery disconnect one lead and put a fused meter lead on the battery and the other lead on the battery cable. look for current drain while car switched off.

No power to cb


first thing is to make sure the power leads to your CB are hooked up. The black wire from the back of your CB need to go directly to the car battery "minus" "-" or to a metal screw which is actually touching metal not plastic. The red wire needs to go through a fuse. Sometimes there are inline fuses, that is to say built into the red wire that you can remove and check. If not the the red wire should go to a wire that is coming from your cars electrical fuse box. Using a multimeter to check voltages, set it to read DC and to be able to read at least 20 volts. attach the black lead of your meter to the same screw or point where the black wire from your CB is at. Next if your red CB wire has an inline fuse remove it. we will test it in a minute. Now where you have removed the fuse, with the fuse out touch the red lead of your meter to the red wire of your CB but the half that goes the opposite direction of your CB. Is there 12 volts there? oops turn on your ignition and test again. you should have 12 volt reading on your meter, or close to that. If so that means you have power up to the fuse. Turn your ignition switch back off. Now set the meter to read ohms or if you have a buzzer symbol, set it to that. Now touch the red and black leads of your meter together, note what happens. something should happen, meter goes to almost zero and probably makes a tone, if you have it set for buzzer. Now touch the leads to the fuse while it is laying on a table. One lead to one side the other lead to the other side. Doesn't matter which lead goes where. You should see or hear the same thing you just did a second ago. If so then the fuse is good. Put it back in the red wire where it belongs. make sure both ends are snug when you fit it in and tighten up.Try your radio again with the ignition on. does it work? It should if what I said checks out. If not then you will need someone to look at your radio internally for a bad solder joint where the red wire comes in or even a bad switch. If you have made the check I suggest and you don't see anything on the meter when you check for voltage. set the meter for DC voltage, touch the leads up to your car battery just to see if the setting is right on your meter and it does work. If it does then continue on. You will need to do this: touch the red wire of your meter to your cars battery "+". You might need a longer wire to attach to the red lead to be able to reach the battery, because I want you to touch the black lead to the black CB wire at the point where it hooks to your car. Do you see 12 volts now? If not the black wire connection where it makes contact with the screw is not really grounded. Find another ground and try it again until it works. If that all checks out and the radio still doesn't work we are in trouble. The basis of this is that the red wire has to end up making a connection to the car battery "+" one way or another and the black lead of your radio needs to go to the car Battery "-". If your red wire has an inline fuse you could just run the wire directly to your battery "+" and the black wire to your battery "-" It will work if the fuse is good and your radio works. If not then your radio needs help. The drawback of running the wires like that are , would be the radio would not go off and on with the ignition switch. woopie!

Only has a -1 on the display


Christoph, Likely you have the meter set to resistance (ohms) and thus, are getting the displayed reading you've described. Also, with the polarity reversed ( positive and negative + / - ) you'll get the negative number displayed in voltage settings.

First off, check to make sure that the battery inside the back of the test meter is new. If your meter has been around for some time, it is likely that the battery should be replaced. Typically it is either a AA or 9 volt battery in most testers.

Once you've replaced the battery, try testing the old battery with the meter set to DC-V and the probes (red & black) in the DC-V connections. Set the measurement scale to the lowest on the DC range and then with the red test lead on the battery's positive end and the black test lead on the battery's negative end, you should be able to get a voltage reading of the old battery.

Now you can check the resistance function (ohms) by setting the meter to the Ohms function at the lowest scale/setting and touch the two leads together. You should get a reading of 0.00 ohms resistance. You might have to zero the setting manually with either a small adjustment wheel on the face of the meter, or with a small set screw on the backside of the meter. (some models have this installed inside the battery compartment also)

Hopefully that's all the issue you've experienced and your meter is now working properly. I hope you find this Very Helpful and best regards!

I have two questions. The first is what is the


The dial is for selecting which of the "multi" things you need for measuring (metering).

Set the dial to the DC area and select 20V or whatever is the lowset DC voltage setting that is higher than the battery voltage.

The meter does not put a "load" on the batteries, so the test is just an estimate of freshness of the battery.

Notes:
The meter voltage does not present any danger to the user. If you are not experienced, do not check any AC voltages.
