Hello this is tim, Today, let's compare what's different between the ZT-702s and ZT-703s. I will list their 12 differences across 7 major sections: product appearance, oscilloscope functions, multimeter functions, signal generator functions, battery life, application, and price. After understanding their differences, choose the handheld oscilloscope that suits you best.
Product Appearance:
The ZT-703s features dual channels, whereas the ZT-702s comes with a single channel.
The ZT-702s is fitted with a 2.8-inch screen, while the ZT-703s sports a larger 3.5-inch screen. Both models boast IPS full-color displays.
In terms of weight, the ZT-702s is 345g, and the ZT-703s is slightly heavier at 390g. However, both share the same dimensions of 1178940mm.
Both models are crafted from ABS+TPE materials, ensuring durability and adaptability to various working conditions.
Product Functionality:
1,Oscilloscope Features:
The bandwidth of the ZT-702s is 10MHz, compared to the ZT-703s's 50MHz.
The sampling rate for the ZT-702s is 48MSa/s, while the ZT-703s offers a normal mode at 200MSa/s and a high-speed mode at 280MSa/s.
The ZT-703s introduces additional features such as XY Display Mode, Persistence Mode, Format Function, Backlight Duration Adjustment, and Cursor Measurement Function.
2,Multimeter Features:
The ZT-702s provides measurements with 9999 counts of precision, whereas the ZT-703s offers 25000 counts.
The ZT-702s measures AC/DC voltage and current, continuity, resistance, diode, capacitance, and temperature. However, the ZT-703s does not include temperature measurement or a temperature probe.
3,Signal Generator Function:
The ZT-703s is equipped with a signal generator capable of producing six different waveforms, a feature not available in the ZT-702s.
Battery Life:
The ZT-702s is powered by a 2000mAh battery, offering around 3-4 hours of usage, whereas the ZT-703s comes with a 3500mAh battery, lasting about 6-7 hours. It's notable that charging issues with the ZT-702s can often be resolved by using a more powerful charger.
Application Scenarios:
The ZT-702s, with its basic features and value for money, is ideal for everyday use,like basic circuit repairnd and educational settings. On the other hand, the ZT-703s, with its dual-channel design and higher bandwidth, is more suited for professional electronic engineers and complex testing environments, excelling in applications that demand high bandwidth, rapid waveform captures, and dual-channel operations.
Price:
Reflecting the significant upgrades and enhanced features, the ZT-703s is priced higher than the ZT-702s. The brand website offers $69.99 for the ZT-702s and $99.99 for the ZT-703s. Both models include oscilloscope probes and offer global free shipping, excluding taxes for Europe. Additionally, the brand website provides a 16-piece measurement probe set and a 2-year warranty for purchases made through their independent brand site, with a $5 coupon for new users.
In this manner, ZOYI continues to uphold its commitment to delivering efficient, user-friendly, and cost-effective instruments to its global customer base.
I think the very bad is the spec that the multimeter only works to 300v and in some circuits like power supply is more as 315v - the 702 was going to 400v . The other is the wrong mA current mesurement. I think otherside its a very nice and good multimeter and osciloscope. From the specs the should build it without a frequencgenerator and with a better higher voltage resistance . The generator is not really usable .
Thank you for your explanation.
thank you bro
The big question for usability: when will they make one that allows you to download the raw data for offline analysis. All of these devices only allow you to export a picture, which is useless for any real work. Until they at least start offering the basic functionality of a desktop DSO scope, I can't justify buying one.
I need a movable oscilloscope to check hight voltage noise. The noise may be 300V up to 4kV. Is ZT 703s the good choice? Can it protect itseft from high voltage over 1kV?
A smart thing would be, if you included a dust protection for the 2 BNC connectors when they are not in use.
that's really a good idea, I will start to make it, and I will ship one to you for free when I make it out.
Hello Sir, can I use ZT-702 as curve tracer? Thank you
Why no code for 100x attenuation? I could measure 220v rms then. Please add in the future firmware upgrade
1x can measure 150v but 10x measures only 300v!! Why & how??
It is very cool! I want to get a free ZT-703S
Hi, I have the ZT-703 (Firmware 138) What is the meaning of the RED marker (on top of the screen? ... and why the timebase has some 'rare' steps? Normal the steps are 1-2-5 (here they are 1,25 - 2,50)
The red mark indicates the middle of the screen. ??? (ruclips.net/video/TH8GI_ZTNCg/видео.html)
Firmware v139 is out
703s would be worth the price difference but no temperature measurement kills it for me.
Edit 5/16/24: I needed temperature measurement functionality so I purchased the 702s. But the temperature measurement is very inaccurate, off by 5C/10F at room temperature. That is virtually worthless IMO. Don't know if I got a defective one or they're all like that.
I think mine has the same issue. Absolutely worthless since part of the purchase was made because of it having a temp reading. I planned to change the cheap meters to this. Even the cheap meters display the same temps as the other meters in the house, so why no fix on this one?
One of them is higher spec than the other but it's not valid to say one is professiinal and the other is amateur / educational. They are both useful tools. Or maybe they are both cheap toys. Depends on your perspective.
The difference in price is so small that the 703S is clearly the one to get unless you can find a reason not to.
I have to say you are right, both of them are good tools.
