Another flat battery! Just two weeks old... (1 Viewer)

[Two on Tour]

Looks like we are both right then Lenny as two models with the same part number with totally different specs, please accept apologies from my unworthy self for ever doubting you.

 

[Lenny HB]

Here's a scan from your eBay link,

No its not, my link was to a search result bringing up dozens of suppliers selling it, not my fault you looked a a supplier that doesn't list the spec correctly.
As I've said I've got one so I know what it does.

The UNI-T UT210E does measure DC current. I've got one.

Lenny linked to a search for that meter on eBay. It's hardly his fault that the first item that comes up in the list is from a crappy seller advertising a UT210E at a very low price, when what he actually appears to be selling from the photos in his listing is an ANENG ST201 clamp meter, which doesn't measure DC current, and which is not even made by UNI-T. It's cheap for a reason!

Battery charged for 20 hours at 4A. Showing 12.7V. I've done the parasitic current drain test and it is as expected at 36mA (I think!?). I'll leave the battery uncharged for a couple of days and see what we get. If it drops volts again then they can have it back!
Thanks to all for the info and Two on Tour for the PM with a very helpful video.

Whilst your readings look to make sense your picture shows you have the red lead in the 10amp socket... But the scale selector swtch isn't selecting the 10amp range..

You could be distracted by the 10A indicator in the AC range? I was using the DC range.

As andy63 says you need one click anti-clockwise to be on the correct scale, 10A socket to match 10A on the rotary scale as I have arrowed in the photo.

I dont think so..you are on the DC range yes ..but not the correct scale for where you have the red test lead plugged in..
Andy

 

[John Barrett]

I don't want to get into a pointless discussion, but the scale markers are just that, within the 10A range capability marked on the dial. The Resistance scale works in the same way. Here's a pic I just took, after moving the scale marker. You will see that the displayed figure has increased by a factor of ten. It's the same value, unless someone here knows different...

Now that you techies have finished (?) has anybody asked yet if the earth has been checked

 

[Lenny HB]

It's the same value,

How can it be the same it's 10 times the current.

 

[John Barrett]

From the Manual. I think that's clear enough!
Connect the black test lead to the COM jack [5] and the red test lead to the 10A jack [8]

(for currents > 200mA) or to the mA/BATT jack [9] (for currents < 200mA).

 Set the range selector switch [4] to the desired range in the DC current measuring range

If you do not know the current, first set the highest possible measuring range and then reduce

it gradually to the lower ranges until you obtain a satisfactory measurement result.

 Connect the test probes [7] in series to the test object.

 The measurement result is then indicated on the display [1]. A negative sign is indicated in

front of the measured value for a negative measurement resul

Looks like the Chinese translator got it wong.

Not getting into a discussion either.. It was on the wrong scale..
I didn't want to speculate in my original post as to whether it would be out by a factor of 10 or not.. As my experience of those meters in the past indicates they do read the current in a different way..
The mili amp and micro amp scales read directly..
The 10amp scale uses a different socket because it passes the current through a shunt and gives a reading that way..
Matters not asl ong as you are sorted

Thank god for your reply , i was just about to go to the van to check.

Strange response when people are trying to help you.

Thanks for the proffered assistance. I didn't want to find myself disagreeing so I opted out of the discussion.
