Cyrustek ES232 2013-GD2X - 30,000 counts

They're actually running the chip within spec. this time around?

The Cyrustek ES232 2013-GD2X chipset is 30,000 counts, but unfortunately, they limited the UT61E+ to 22,000 counts. (maybe hacking it?)

The previous edition (UT61E) had a very high burden voltage of >800mV at the 100mA range. Has anyone seen if they've addressed this in the new + version of the product?

Good morning, has anyone tried the connection to the PC with windows 10, if it works with the unit software?

Does anybody even measure hFE these days?

I do...  .

[robdejonge]

The burden voltage for this meter is said to be approximately 550mV.

Sharing this information here in case others were wondering the same thing. Darren Walker, who did the review that kicked off this thread, replied to me on Twitter with this information. The previous version (UT61E) had a burden voltage of about 850mV, so this is an improvement, but it's still too high for my linking.

Me too  However, a cheap transistor tester does much better job.

Works fine. However, the company did not care to upload the software to their website 

[Adrian_Arg.]

ok, where can I download it from?

Hello friends!
Sanat Klaus brought me a present under the Christmas Tree! It's new UNI-T UT61E + Plus!

It has a great design! This is the most beautiful tester I've ever seen!
But there is a fly in the ointment in a cup of honey!

Are you interested in the text review and comparison with Brymen BM869S(Plus Edition)?

Accessoires Included:
- 2 probes. They are tougher than the brymen.
- Ugly Bag + 2 high voltage clips. It was a gift. Made of poor material and does not hold its shape. hFe adapter does not fit there. Brymen's bag more better!
- USB computer cable with optical sensor
- hFe adapter
- Waste paper. Instruction and warranty card.


From the pros, it measures quite quickly. At first glance, it is roughly comparable in speed to brymen. Warns with a signal and a flashing LED about high voltage!
It fits very comfortably in hand! More convenient than brymen. Brymen is huge and not comfortable.

Cons, no temperature sensor, it's in the D + model. Apparently it can be purchased separately and you can measure the temperature in the hFe mode. NCV very slow.

The screen is not bad. But worse than brymen. It has good viewing angles when viewed from the side or bottom edge. Best viewing angles from the bottom edge of the view at an angle of 30-60 degrees. When viewed from a 90 degree angle, the image is not clear. The worst viewing angles are from the top edge, as soon as you slightly deviate from 90 degrees towards the top edge, the image immediately becomes completely unreadable. Apparently this is due to the cunning polarized coating, which is designed for more viewing from a natural angle.

Hello comrade,
It is unfair to compare UNI-T UT61E+ with Brymen BM869S as two are from completely different price leagues. I would say the NCV function of UT61E+ is rather insensitive than slow.
Good purchase anyway.

Thanks comrade!

I just wanted to show the measurements with both instruments so that people can appreciate the quality of the measurements. The main difference is CAT, Brymen has better security. UNI-T has slightly less accuracy. For the repair of equipment, this is an excellent device, it fits perfectly in the hand. I'm also interested in how it reacts to power supply ripples, and at what frequency the measurements will float.

... NCV very slow.

... NCV function of UT61E+ is rather insensitive than slow.

The NCV only beeps when it is right next to the live AC wire, I've noticed that on my 61e+. It is certainly not useful for identifying the presence of live AC wiring behind walls. Perhaps the use case uni-t is supporting is where an electrician has direct access to a potentially live wire. In that case the electrician needs to know if that specific wire is live, not just whether there is live wiring in the vicinity.

Or maybe the NCV on the ut61e+ is just garbage 

[nullik]

rernexy only corner with label NCV works. But my cheapest $5 screwdriver can faster Identify the AC wiring. Also screwdriver can ident phase wire. For me, UNI-T NCV is a dubious function. This is only if the entire instrument is at home or garage and nothing else is at hand.

[Per Hansson]

It is really out of touch how the D+ model has LoZ and temperature measurements when the E+ model lacks that but gets hFE to "compensate" geez!

[rernexy]

hFE for a meter that is marketed as an "Electrician" meter too. I can't understand why electrician's would be concerned about hFE in their day to day work. AND you need that huge adapter to use it too.

OTOH only 2 days ago I did use the 61e+ hFE function. Yes, I actually used it.
It was to sanity check an npn BJT in a sot-89 package. Yes I'm a glutton for punishment.

Soldered a breadboard jumper wire to the collector, then plugged that in to the collector hole on the hFE adapter. Connected 2 breadboard jumper wires to the base hole and emitter hole on the adapter, then used those 2 as hand held probes on the sot-89.

No problem! You can simply throw the hFe adapter in the bottom of a junk drawer and forget about it.

G'day, mate, 
You also have to know/remember the pinout and type of a transistor to connect it the right way, while a cheap transistor tester can do it all for you.
The NCV in my multimeter also works only when it directly touches a live wire.
UNI-T should have employed the full potential of the used ADC chip by updating the resolution of the multimeter from 22000 to 30000 count instead of hFE and such.

[nullik]

rernexy, I am not an electrician, but sometimes it becomes necessary to work with high voltage. For example, I recently did home renovations, and it was necessary to shift the wiring and add sockets. Also in the country, and in the garage.

I bought a tester with the hFe function because I need to measure transistors periodically. Cheap Chinese LCR transistor testers lie, and show different values ​​every time you turn it on and on a different battery charge. By the way, they also measure LCR crookedly and the values ​​are far from real. Unfortunately, I have not been able to check the quality of these measurements in UT61e+.


I have a Chinese AD584-M module with a voltage reference of 2.5v, 5v, 7.5v, 10v. Uni-t ut61e+ shows closer values ​​to those indicated on the calibration sheet created on the HP 3458A.
Brymen bm869s has more discrepancy in readings. Probably these calibration data are fiction and made by some Chinese tester. I doubt uni-t ut61e+ has better accuracy. But I don't have  better voltage reference at hand to check it.

UPD. I found a way how to place the hFe adapter in to the bag. After I changed the probes and put the probes from uni-t ut61e+ on to Brymen bm869s, it began to show closer values and has better accuracy. Probably Brymen soft probes have higher internal resistance due to thinner conductors for better flexibility.

Probe resistance will have no effect on voltage readings.

The meter itself has a resistance of many megaohms when reading voltage so a few ohms from the leads makes no difference.

[nullik]

Fungus, I do not know why the different test leads shows different results. The difference is about 10mV.
