Who care how its look? More interesting how its work, i know that for example 2c23T is not measuring a lot of time, looks like while it draw image, so if you want to catch short signal it miss it completely often.
On balance I think I prefer the ZOYI ZT-703s. The interface seems to be more user friendly and the button layout less cluttered. Thanks for the comparison, it really helps in making a decision.
I need a temp sensor as i work on model trains and i need to be sure the smoke generator is hot enough. But I do not like the setup of the FNIRIS having to go back to home all the time. I am so used the dial but love the need bid screen. I guess I would want the ZOYI them find a temp reader separately. Dennis Thank You, Dennis
Was very close for me, both seem to have good features but for scope use mainly the FNIRSI 2C23T tipped it for me. Would like both really the ZOYI for multi meter and FNIRSI for the scope but want a scope more as i have multi meters already. Been looking for a scope and the FNIRSI seems suitable. Good review. Thanks.. Keep up the good work .
Id love to get my hands on the zoyi as its not available locally in ny country. This would go really well with the rig im building for trouble shooting pcb faults and verifying that all works as intended.
Either is attractive, but I prefer the ZOYI ZT-703s, because better bandwidth and XY mode. It was easy to decide because your review is very concise and you showed exactly what I needed to know. Now if they performed the same, I would prefer the smaller flatter form factor of the FNIRSI.
I have tried both of these instruments and my final choice was the 703S. I wanted to resolve an analogue video wave form and the 703s was better at that. The sig gen was less of an incentive as I already have a very capable one and the scope was the most important element to me. Its unfortunate that the sig gen cannot be used at the same time as the scope, you need to connect another scope to the side connectors to view it and you have to press the mode button to clear the sig gen set up screen and this enables the scope again, but the output changes to the 1KHz probe set up sig gen, its not the same as the main one. Other than that with the latest firmware V1.3.9. its a very competent tool.
If you need XY mode 25k resolution on multimeter and bigger size then choose Zoyi. If you want better wave gen more intuitive operation and smaller size then choose Fniris. Both for the price are amazing to me
Haha, maybe because many of your viewers already have 703s? You made a good comparison. The 2C23T seems less wobbly, more functional construction and a more developed waveform generator. The 703s is more efficient and has stronger oscilloscope with X-Y mode, which I believe is more important. Both are good, and I hope both can learn from each other and improve in the future. Thank you
I am assuming that Oscilloscopes are more sensitive and advanced than EKG machines, yet I can not detect whatever EKG machines are detecting, or maybe I couldn't figure it out. You are more experienced than I am, can you please tell out how to do it and what I am doing wrong? Thanks for your videos.
I like 703s, because of XY mode. Possible octopus or V-I curve tracer. But 2C23T is also good in other ways. Maybe I could make some modifications to 703s, to have microamp / nanoamp range or simple back hook also. Thank you
ZOYI 703S kocham ten produkt miałem wersie 702S a ten 703S jest wspaniały i lepszy Jakby dało się jeszcze używać tego lepszego generatora sygnałów i oscyloskopu jednocześnie to by był ideał I want ZT-703s
Are you interested in recycling DC power supplies at low prices? I have a lot of DC power supplies with damaged packaging but no place to dispose of them.
Tim, do you know of others having problems with V1.3.9 on the ZT-703S? I'm doing some testing with a Hantek DSO5202P and a DDS Signal Generator, and the measurement function is often not updating or updating with incorrect information while the Hantek is getting the measurements correct. I hope future updates will be forthcoming on the ZT-703S after some internal software quality review. I noticed another problem while attempting to use the AUTO function. A long press on the button does nothing. You have to press and release the button quickly for the AUTO function to engage. Perhaps a long-press maps to a future function? Either that, or the keypad debounce software needs some tweaking. Regards.
@@tim1tim2 Allow me to experiment some more. Last night, I determined that the time-base can affect the scope's ability to estimate the frequency. Also, to do a good comparison, I think I need to use a BNC "T" connection so both the scope and my Hantek DSO can be connected to the signal generator at the same time.
Hi Tim, I just bought a new ZOYI ZT-MD! LCR Bridge. I Can't find any Firmware updates for it. My device has version 1.5, but a video explaining how to update it seems to indicate that there is a version 1.6 available. Can you help?
totally agree, also as many sugested, 1 beep in diode 2 analog meter removed. It really adds nothing (only increase de cheapness factor) 3select from diferent layaut or visual configurations in DMM mode. (BIGER numers , choose colors.etc) to take some use from that screen
The third dimension to capacitor testing is leakage current. A leaky capacitor (parallel resistance) will fool capacitor measurement devices. None of the devices shown in this video check leakage current. It's possible to have a leaky capacitor that measures good otherwise. Some leakage current can be expected with electrolytic capacitors and tantalum capacitors, check the data sheets how much is allowed. Ceramic capacitors should not leak at all. Tools to measure leakage are uncommon. It's possible to construct your own based on tutorials.
@@saboteur922 D относится к последовательному сопротивлению, утечка относится к параллельному сопротивлению, обычно при более высоком напряжении. Я не думаю, что D можно использовать для утечки.
