Martin.

I would be remiss if I failed to thank-you.  Your multi-part review for the 61E are very informative and was very helpful in my choice of meter.


Thanks!
Rick

Thanks Rick...appreciated!

Hi,

I'm new in this forum. I'm thinking about buying a new DMM and came across the Youtube Uni-T UT61E buyers guide which was really helpful. While having a look at the specs of the meter, I stumbled upon one contradictory point in the manual of the device. I couldn't find any reference to this on the internet, so I thought that maybe someone here could help me.

In the datasheet, it states that the meter has the following ranges for current measurement:

220.00uA/2200.0uA/22.000mA/220.00mA/2.2000A/10.000A

But when looking into the manual of the device, I can't find any reference to a 2.2000A range. Has this only gone missing in the manual or is the meter really missing this range and the datasheet is wrong? This would really limit measurement accuracy in this range.

Can someone confirm that the meter has a 2.2000A range (the meter will show something like 2.XXXXA will the full 4 1/2 digits? I would really appreciate that.

Thanks for any help!

Regards, Thomas

Hello.

Nope. There is no 2.xxxxA-Range.
In the A- setting it shows immediatly "0.000" and "manu".

Thank you for the fast answer!

Unfortunately, this is not the answer I was hoping for. The fact that the 2.2A range is missing actually would make the meter unusable in this range, if it behaves as specified. The quoted accuracy for the 10A range (+/- 1.5% + 50) results in a relative measurement error of >10% for 220mA-500mA and still > 5% up to 1A! (see my attached chart) This wouldn't qualify as a "meter" anymore in my opinion.

The specs of the meter are otherwise excellent, regarding it's price. But as I use this current range quite often, this could really be a no-go. Does anyone have experience with the actual accuracy in this range?

Btw, I collected and visualized some accuracy specs for different meters and different measurement modes (the attached chart is one part of that). If anyone is interested, I am happy to provide the other charts as well.
