 Should I consider the cost of a digital multimeter?

Of course, you should but there is no point in buying a cheap meter that does not deliver and breaks quickly. I was always taught VALUE by my father, buy once and never buy again. Consider the upset and cost of having to order a new multimeter. Scheduling a job only to find the meter (digital or analog) was faulty.

Consider the specifications – will it do the job and a bit more. Will it last? what do other people think? Buy the right meter for the job irrespective of the cost.

Remember that the best multimeters need to be calibrated occasionally to keep them at optimum performance. Because of this, it may not be wise to buy a very cheap multimeter that you cannot calibrate. Instead, buy a meter which if need be can be calibrated. This will help you make use of the meter more effectively over a longer period of time. You have a decision, spend a little more and not worry about a non-functioning multimeter or save money now and buy one that has the bare minimum functionality.

Accuracy – Nice to have but do you need it?

Cheap meters serve a market where absolute accuracy is not required, they tend to break easily when they fall to the floor (very common). You will need to replace them often, but they do have their place. Usually, they cannot be calibrated but hey I’ve had cheap meters and they have done the job. They come and go with amazing regularity, especially when working on site. You will find that the higher-priced models will last for many years (25 years in my case) and still work well but then again they may need calibration from time to time to remain accurate. Your need and budget will determine which multi-tester you choose.

Is it rugged? And will it last?

Understand this. You WILL have accidents. If you lend it to “friends” they will disappoint you. They will not treat it with the respect it deserves. They will do all manner of things. If it is to serve you well into the future it needs to be both rugged and of quality.

Will it last? – Normally good quality branded meters that are of a superior design and use better materials will last a lifetime.

General Safety

If you need to test higher voltages or currents you must consider whether you or the meter may be damaged should you make a mistake. There are four basic cat ratings I, II, III, and IV. These refer to the type of work you are doing. The categories will vary slightly between the US and Europe due to the different supply voltages. Whether a household, installation of power equipment, or beyond, you will need to go for the highest rating your pocket can afford. You may need to consider other things such as input protection (for the meter) and shrouds on the leads (for you).

Digital or Analogue?

DMM digital multimeters are good for accurate regular voltages or waveforms such as battery or household electricity. If confronted with irregular alternating waveforms the readings will jump all over the place. When used properly they will give very accurate readings. Additionally, a DMM digital multimeter will come with many extra features.

Analog meters tend to give a clearer reading over all types of input. However, they can be less accurate especially on electronics due to loading factors on the circuit under test. They also tend to have fewer features.

Conclusion

As always you have to answer that question – what am I going to be using this meter for? How much can I afford? Is this meter going to be a tool of my trade or hobby? so many things to consider. I sincerely hope this site can help you decide what is right for you.

How To Use a Voltmeter To Test a Car Battery

Tips, tricks, and info to help you with that dead car battery. We have all been there, need to get somewhere quickly but the car will not start. Lost time, lost money! it’s at times like this that simple skills such as knowing how to use a voltmeter to test a car battery can be a lifesaver.

The meter in many cases does not have to be an expensive piece of kit, (although that’s nice), many of the less expensive models will give you that much-needed information. In many cases a simple check of the battery will tell you that’s it’s dead (discharged) and you can act accordingly.

More than once I have popped open the bonnet (hood) on a cold and frosty morning (at 5 am) to confirm my worst fears. 10v dc across the terminals ahh, time to break out the jump starter or if I’m lucky, slap in the old fully charged battery that I keep just for emergencies. Good information makes for a good decision!

Step by Step Instructions

OK so now it’s time for the action
If you have a battery that needs topping up with water then check that each cell has the tops of the plates covered by around a 1/4″ inch (6mm) of distilled water. Not bottled water as some people say.
Charge the battery for 24 hours, there is no point in testing a naturally flat battery. After the charge turns your lights on for a couple of minutes to dissipate any unnaturally high voltages.

1. Often overlooked – Turn the voltmeter on and make sure that the meter and test leads are functioning. Ensure that the Black lead is plugged into the hole marked “COM”. Plug the Red lead into the hole marked with a variety of symbols such as “V”, “Hz”,” Ω” etc.

Set the meter selector to the ohms Ω scale and touch the 2 open ends of the test leads together. A reading of zero is what you need. Assuming you get a reading of zero proceed to step 2. If you get a reading of “OL” either the voltmeter or the leads are at fault.

2. Change the meter selector to a DC voltage in excess of any voltage you may be expecting, normally 20v or possibly higher if you have a large truck or something similar.

3. Check the terminals for corrosion i.e. a blue crystalline deposit. If you see a deposit, turn the ignition off and disconnect the leads from the battery. Clean both the battery and leads with abrasive paper. Apply vaseline or copper grease to the battery terminal and reconnect.

4. With the engine turned off and the voltmeter set to a DC voltage touch the black lead to the negative terminal of the battery and the red lead to the positive terminal. You should get a reading of around 12.6 volts on a good fully charged battery, Again a safety shouts out, whatever you do make sure you do not cause the positive and negative terminals to become connected directly. It will cause quite a bang and possibly a lot of damage.

A practical safety tip, if using a very cheap voltmeter – cover the metallic part of both probes with insulating tape leaving just the tips exposed.

5. Repeat 4 above, this time with the engine running. Should read around the 14.4v mark indicating that the regulator is charging the battery normally. That’s just the start of the fun you can have with your brand new multimeter.

6. Now to the BATTERY LOAD TEST / CCA (Cold Cranking test) – Some batteries work beautifully all summer long but die during the first cold snap of the year. That’s why we do the “load test”

In an ideal world when we turn the engine over the voltage across the terminals will not drop below 10 volts however the perfect world is not upon us yet. In an ideal world, you will have a voltmeter/multimeter with a min/max function, or as an alternative, you could use a load tester, a purpose-built device for stress testing the battery.

After connecting the voltmeter leads across the battery you simply crank the engine over and allow it to run for a few seconds before turning the engine off. Check the meter to ensure that the min reading does not drop below 10v (9.5v may be) and the max reading does not go above 14.4volts. If these conditions are met then you are good to go.

An alternative to consider: There is a rather nifty voltmeter that plugs into your cigarette lighter. Makes it a little easier to read the voltage when cranking the engine over on your own and allows constant monitoring of the charge of the battery.

Had a look at a few products that may help (above) – Would be great if you could check them out!

None of the instructions either in the video or text are hard but as always when dealing with any form of electricity please take extra care. Any new skill is a source of pleasure, so give it a go and give yourself the peace of mind you deserve. As a quick check, a new fully charged car battery should read around 12.6v (DC volts) when the engine is turned off. However, when the engine is running the voltage should rise to around 14.2 volts plus or minus 0.5v.

Hope the above helps.
