- Well This is a Video Shoot Explaining The Difference Between a Digital ESR Meter From Mr Bob Parker " Australia " And a Analog ESR Meter From " Creatronica " .In Short This Removes The Myths Associated To Analog ESR Meters Created By Some Forum And Their Members .I am Not Saying That Analog Meters Are Better Or The Digital Once ,What i am Trying To Say Is That Both Have Their Advantages And Disadvantages .Lots of People Would Agree To Me On This After Going Through This Video .I Too Am a Repairmen Who Repairs Computer "IT" Products For a Living In India .
Sir ,
Both Are 100 Khz .BTW In This Video We Tested The Resistance Cos I Wanted To Show You The Accuracy And Resolution .You Folks Can Check lynx-india For Your Purchases ,We Take Paypal And Ship Worldwide .No Hankie Pankie Here By Us .
Axel ,thanks For The encouragement .BTW ;-) We Say The Same Things For American English .
i hate indian-english Sound. is no english nor american . but on this one i just love the way you presented the raw Facts/numbers. BAM! there u have it. spot on. in fact, in most cases you wont even Need a calibrated scale at all to make use of These cool analog meters. well done dude!
Guys ,2 Orders Were Delivered To USA customers From India
well can i have some kind of a link for that ,if you buy the tool you will know what it uses then buy the probes
can i use a ideal test pro cat. no. 61-360 multie meter for testing cap's or no
SeanB ,
Thanks a Tonn Mate For These Comments ,Catch You On EEVBLOG ;-)
It would be nice if you could test/(take some measurements) of the inductance and capacitance of each of the 4 twisted pairs inside a cat5 cable(any ethernet cable will do). As you might be aware each of the twisted pairs have different turn ratios. On the subject of crosstalk, which is the supposed reason for this, it can wait for another day. I just want to see how the turns ratio effects the Inductance and capacitance. If you would, could you please take the wire twisting to the extremes.
Amarbir I seem to prefer using an analog meter.
Much better video, nicely done.
Stop being so defensive, both are good meters, not network analysers, but both work at the job well enough to tell bad, from marginal, from pretty good. At least it enables you to tell the not bulging and popped dud from the not bulging and still working one. If the case is looking like it is a balloon, or the sleeve is split or shrunk down on the side you can tell it is dying or past dead, only waiting to go bang.
Well in that case place a order on lynx-india we deliver worldwide
Hi,
I don't think this is a fair comparaison. Firstly because what you're mesuring is simply a resistance, therefore the same comparaison could be done with any analog or digital multimeter and achieve similar results.
ESR is not something that can be measure using DC, at least based on my understanding of ESR, therefore what's the purpose of that DC mode on the CapaCheck device ?
As per the chart's info on the digital ESR, working voltage is significant for a given capacitance. How does the CapaCheck device deals with the working voltages, since there are only references to capacitances on the scales ?
How about the frequency at which the capacitors are tested, is it the same for both devices ?
Globaly, I think that a meaningfull comparaison should be done using good and bad capacitors, which would have different working voltages. Based on the evaluation results, we would be able to come up with something more realistic and see if both devices are flagging the good, not so good and bad capacitors adequately.
Generaly speaking, for the general electronic enthousiasts, ESR doesn't need to be an exact value, it's rather permissive. However, when a circuit is acting up, the odds that if a capacitor is the source of the problem, its specs will be way off the expected values, therefore a precise reading would be simply useless as the only thing we care about is if the measured value is within an acceptable range.
I have few ESR meters, none analogic however, and the readings for any given capacitor are all within a range that allow me to classify the capacitors adequately so a precise ESR reading isn't much of a necessity, at least for me.
IMHO, regardless of the meter you're using, as long as the readings are reflecting the actual situation, this is what is important because we're basing our actions, as to replace or not a given capacitor, on the info returned by our meters.
If any given meter is always off, reading wise, it simply doesn't belong on your workbench anymore, period.
Boss ,
Wrong Info You Have Works In Both Directions .Its Not a AVOMeter ;-)
