The Ω2W/Ω4W button is not to eliminate the resistance of the test leads. Ω2W is for a resistance measurement using 2 wires (most common). Ω4W is for a 4 wire resistance measurement, which uses the hisense and losense ports and connects the resistor across all 4 wires, which is more accurate but more complicated than the 2 wire measurement.
Luke Eyles Thx for your reaction. According several internet pages it is done to eliminate the resistance of the test leads. Specialy with low resistance the current Flowing true the leads wil give a drop of voltage.
Yes. It's also called "Kelvin Resistance Measurement", and it has some advantages probably not obvious. www.allaboutcircuits.com/textbook/direct-current/chpt-8/kelvin-resistance-measurement/
By pressing "shift" will it then measure amps, and if yes, will it measure microamps range? What was your cost? Have you had to upgrade the firmware? 73 DE W8LV BILL
I am considering grabbing one of these for a bench meter. All i plan to use it for is everyday measurements i want done with a bit more accuracy and some kelvin 4 wire resistance measurements. It looks very nice.
In this advertising for OWON all multimeters work good, but for me XDM2041 don't work property. th-cam.com/video/_IZAMFmYTIY/w-d-xo.html In resistence measure the last three digits every time are changet. I can reading only 2 digits of value. How this issue I can fix?
Thx for your response. Still use it on daily base without any problems. It is good to reread the manual after a while to discover new functions. Overal happy user!!
Thanks Mario, the issue was already confirmed by Siglent, for measurements below 5% of the range, 25mV, you need to add an extra error of 0.1% of the range, i.e. 500uV. The total error will be 600uV. You have this spec in a foot note with small letters... You can check manual, is there. The 5% spec is common in top devices but not for ranges of 500mV. Many thanks for your help 😃👍
Hello (I am writing through the translator google) Is the meter reset in the ACV range when the input is short-circuited? Is the input also resets in the ACA range during a short circuit?
Nice video 👍. Please could you help me? I'm facing an issue with my siglent. Have you already try to do an AC voltage measurements with very low amplitude voltage values? As example with 1mVrms @ 1kHz my siglent gives a wrong values... I have 1.4mV of amplitude in the scope... Thanks, Hugo.
@@MarioRiesebeek ok many thanks! Sorry because my Channel is in Portuguese... i'm trying to do a THD meter with the multimeter but it gives wrong values with small amplitudes... Have a nice week 👍
You will have a 1.41mV amplitude (peak) on your scope when measuring a sinewave with 1V RMS. A sinewave has a peak at SQR(2) * Urms. So probably your measurements are absolutely correct. If in doubt, try to compare with a DC-voltage. AC-measurements are more complicated than pure DC, as in addition to waveform (which can be solved mathematically via fourier-transformations), you will have a reactive component as well as a resitive component. And the reactive component is the sum of inductive and capacitive reactance. Cables, connectors etc. will have an influence of those parameters.
Thanks@@erikas6874 in fact the device has a limitation! In the specs tables you have a maximum error of 100uV, 10digits. However, in small letters you have a foot note that says to add an error of 500uV when the voltage is less than 5% of the range, 500mV -> 25mV. This means that the device has 600uV of error, 60digits! Not 100uV. This with the leads shorted. The worst is that you cannot use relative measurements. Thanks for the feedback 😃👍

Thanks, Mario! Very exiting multimeter. Never seen so many options on other bench dmm

trying to decide between this and the Rigol DMS3058e
accuracy of mv ac please... your experience and tests,,, not what they print
Goede instructie video.
2 weken geleden heb ik deze multimeter gekocht. En met veel belangstelling gekeken naar je uitleg.
Dankjewel

Does it have capacitance?
In comparison to ANY handheld, this multimeter shows EXACTLY HALF the resistance value measured in circuit.
Why is that ?
VERY GOOG MR MARIO THANKS YOU

After two years of use still happy with this meter!

In resistence measure the last three digits every time are changet. I can reading only 2 digits of value. How this issue I can fix?
Very instructive and great video. I just bought one. Which is your overall experience over the time? Still being a good meter? :) Thanks!
Thx for your response. Still use it on daily base without any problems. It is good to reread the manual after a while to discover new functions. Overal happy user!!
@@MarioRiesebeek Great. Thanks for your kind response!
When you go into dual mode the refresh drops, is that expected? If yes would you say that it drops /2 or /4 from single mode?
Too bad you don't show how to use USB slot
what is cheapest way to measure 100 khz 50 micro volt square wave... yes micro
Cursusje engels mayb??
Is goed, zeg maar wanneer :)
Tried it, feed in a 1 kHz ,030 volt signaal. Both scope and siglent shows 10,35 mv rms. Are you sure your scope is showing rms voltage ??

how can i measure power using it?

I bought this meter about 2 months ago and have not been able to get out of the Math function. You have a answer on how to do this?
TheGordy1950 all the math functions you switch on, you have to switch of seperately.
Hello (I am writing through the translator google)
Is the meter reset in the ACV range when the input is short-circuited?
Is the input also resets in the ACA range during a short circuit?
Thank God doctors are not using Google translate during surgery ;)
Great demonstration of this meter. Is it possible to display a/c volts with a bar scale and the frequency at the same time?
Yes! Just tested it, with dual mode you can display freq and voltage (with bar) at the same time. Your email then I send you a screenshot
@@MarioRiesebeek Awesome, thank you for the quick feedback.
When off, is it normal for the power button to blink green?
uno dos yeah! Very irritating:)
leuke korte informatie video.
Could you please make a teardown video for this Multimeter...
Sorry but mine is calibrated so i dont like to take it apart :)

can u measure less than 1 milli ohm
kay bhee no!
Horrible, uninformative video.
Gary Norris your just not that smart
Thank you :)
Gary, sorry that this model did not have an option to watch the Dukes of Hazard.
