Using a UNI-T UT210E clamp meter to test circuits for current 

NCV = Non Contact Voltage. It detects AC by putting the probe near a cable etc. even when insulated.

Top tip for using the UT210E clamp to measure very low current, if you wind the wire through the clamp twice you double the reading, winding it 10 times increases the measured current 10x so you can get milli amps to into range of the meter.... just remember to divide the reading by the number of wire turns.

Who else, watches Mike demonstrate a tool then searches on the WEB and buys one? 👍👍👍👍

I like your style and presentation... no music or waffling on for 20 minutes before getting to the point! I just bought one. I have a high parasitic drain over night and can check my individual circuits and globally to, without removing a battery lead and inserting my meter in series. don't want to lose setting in the car. This is easy! Thanks

Have added lights, indicators and a beacon to my vintage tractor one of these will be useful to size the fuses.

Generally I curse the volt, watt, and amp. However, your explanations and that handy tool makes diagnosis a little bit easier.

if you're not sure how many amps ' set your meter to it's highest scale , then wind it down to suit ' .. very wise words , i've seen many apprentices blow an expensive meter by not doing this

Another thing to note is that most things draw a higher current at start up or switch on the settle down to their normal running current. Keep up the good work!

Nicely done chap! Even I barely dribble when you explain stuff.

I bought one of these after seeing it feature in one of your previous videos. Great bit of kit because of the low DC current range on it. For the cost, an essential test aid

Got Flukes too but this is very versatile and pretty accurate little meter and clamp meter for very little money and now also carry it in my vehicle.

That fan is more powerful than the one in my smiths heater in my 2a. 😂. Good film again, thanks Mike. 😉

One of the best explanations on RU-vid, great work dude!

Your a Gentleman Mike thanks

Great, another tool to buy. Thanks again Mike!

Great information. Thanks Mike!

The meter is great for checking insitu 300TDI glow plugs and working out which one might be faulty. Total current is about 55 Amps, which drops after a few seconds. It's great for finding parasitic current draw too.

Great meter. I always carry it in the Defender. Caused some suprised looks on the faces of some other offroaders, when they couldn't find the fault in their recent solar panel setup and I used the UNI-T to measure the currents without dismantling their circuit; they had never seen a clamp meter before :-)

NVC DIY FIX: use Bounce sheet (the sheet you put in your drying machine) and rub it on the meter and the test lead and the housing... it will prevent the meter from getting statics and beep for no reasons...

I use a battery disconnect on my '72 Series 3 when sitting for any length of time.

Thanks Mike very valuable information for future reference 👍

Disconnect the battery, place the meter on the cable you want to measure, THEN zero the meter... reconnect the battery...

Another useful video Mike.

Clever man,hmm that gauge looks like the one l am missing,you haven't been holidaying in Australia lately 😁😁😁😁

I have seen a stereo install cause a problem do to the install not the stereo it self. A screw they used nicked a wire in a wire bundle of the vehicle just enough to cause a high resistance short which drained the battery within a couple of days.

Hi Mike NCV stands for non contact voltage for checking if current is in a cable

Have the same meter, it's excellent.

NCV Yep more easy that having to poke the insulation with a needle. Voltage but no current often terminates in a bad or missing ground. BTW those UNI-T multimeters are rather fine for the price .

I tried the fuse pulling trick once. The drain was across 4 different fuses. So we just put a manual disconnect on the battery and used that if it would be parked for more than a day.

And how do you find where you have short? Cheers King Mike. 🥃🎄

LR2?? That a Disco 2 Mike?? Mine drained its bat because the RF receiver in the roof had got wet.

....your method is fine until you have the problem that's plaguing my Defender atm....the intermittent parasitic draw has returned....I have checked every fuse multiple times and am still none the wiser as to where the draw is coming from....I can measure it at the battery from time to time, but as soon as I start testing it disappears!....I'll catch the little bugger one of these days...😂
