Hello,

I received CH341A programmer and hacked UT210E DM1106EN multimeter. Big thanks for your work !

I set :

9999 counts
100A to 1000A
Backlight timer disabled
APO 30min
DCV / ACV / DCmV / ACmV
Continuity / Diode / Resistance / Capacitance
2A ACA / DCA / ACA dotless / DCA dotless
NCV / NCV mV / NCV dotless A
Alarms:
DCV "beep" 750V / DCV "OL" 1000V / ACV "beep" 520V (because Vamp 750V) / DCV "OL" 750V (because Vamp 1000V)
"A" warning disabled (because beep in Dotless 2A and NCV)

It is possible disable beep sound when changing mode ?

Make μF default range for capacitance ?

100A to 1000A

Hmm...makes it any sense except you can set it to...

stop the beep? no.
set the range switch to start with capacitance before resistance/diode - yes.

El Coyote are making quick experiment to 400A.

I mean DMM display capacitance measurement only in μF.

no, you cant disable autoranging without pressing a button.

My UT210E's current measurement are way off (around 300mA on 20A range and 150mA on 2A range) after I did the calibration (by pressing blue and yellow buttons while turning on the meter) .I did realize that I shouldn't have done that after reading the whole thread

. Is the calibration is the main reason that gives the inaccurate reading.I did clean the contacts of the selector wheel but the readings are same.
could somebody help me out whats wrong?
here is my eeprom data

Just bought an UT210E from UNI-T Official Store on AliExpress, and it come with a missing row of 19 capacitors on PCB.
It works fine as far I can tell, just I am not sure how good is this “new version” of it. See the pictures.
Does anybody have an idea of the role of the capacitors, and the values of them.

Hydron · « **Reply #659 on:** June 14, 2019, 01:15:26 pm »

I think the row of missing caps is normal (from memory of the innards of mine), but I could be wrong.

You at least have the newer chip which supports a higher number of counts (after EEPROM mods are applied).

Mortymore · « **Reply #660 on:** June 14, 2019, 02:35:31 pm »

All I can add is that I have one with caps, and my father-in-law has one without them, and his clamp is more accurate than mine. But that may be only casual.

Svici · « **Reply #661 on:** June 14, 2019, 02:46:51 pm »

Actually I was thinking to add the capacitors myself, but I’m not sure what values are needed, so maybe I just leave with it as it is.
Waiting now for the eeprom programmer to arrive from China...

Have you tried the zero button?

Have you demagnetised it?

When testing, are there any other magnets near by?
Are there any large ferrous object near by?

I tried everything,I even built a degaussing coil for the demagnetization.Even after the degaussing the readings are still the same

Sounds like the calibration has been disturbed.
You will have to recalibrate the meter.

You will need to set up known values of current, possibly Volts and Ohms

the voltage, resistance and every other readings are spot on except the current readings.
Do you know how to re calibrate the meter?
I could setup known current values but I don't know how to calibrate

MarkL · « **Reply #667 on:** July 21, 2019, 04:06:28 am »

I just picked up a UT-210E from Amazon. A great little meter for the price.

Can someone explain what "V.F.C." mode does? A half hour of searching and playing with the meter itself has not turned up anything definitive. Thanks.

bitseeker · « **Reply #668 on:** July 21, 2019, 08:04:07 am »

VFC mode engages a low-pass filter for use when measuring variable frequency drives. Hold the Select button for 2 seconds to enable it.

Cool!

I've had mine for a while and never knew about that. You learn something new every day

So long tread

UT210E was invented 6 years ago
What about new alternatives in 2019? (I.e. same performance and Low DCA range)

Few "noname" clamps based on the same chip but has 6000 counts in stock
Any opinions? I didn`t see "zero" or "range" button. Why?

TurboTom · « **Reply #671 on:** July 30, 2019, 03:40:52 pm »

Except for the third one (which has a "Zero" button), the clamp meters shown are AC current only. Hence they don't need it.

001 · « **Reply #672 on:** July 30, 2019, 03:45:15 pm »

Thanx a lot
and what about ACM91 instead UT210E?

Is it possible to get 9999mA range instead 2A?
What is maximum crest facktor for DM1106EN in 9999 mode?[/list]
