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.
