The Genesis of ZOYI’s Innovation
ZOYI, under ZOTEK Instruments Co Ltd, has a rich history of innovation and excellence in the field of digital measurement tools. With over 40 years of experience, ZOTEK’s founders have been instrumental in pioneering developments in digital multimeters and oscilloscopes, leading to the creation of the ZT-702S
Unveiling the ZT-702S
The ZT-702S Digital Oscilloscope stands out with its robust design and superior functionality. Measuring 177 x 89 x 40 mm and weighing 328 grams, it features a sturdy appearance with a fold-out backrest for optimal viewing angles. This semi-automatic device offers ease of switching between multimeter and oscilloscope functions, making it a versatile tool for various measurement scenarios
Advanced Display and User Interface
The ZT-702S boasts a 59 mm x 43 mm color display, offering a crystal-clear view in both multimeter and oscilloscope modes. The intuitive interface, with function keys that change depending on the mode, adds to its user-friendliness. This seamless integration of display and function keys makes it easy for professionals to switch modes and settings efficiently
Comprehensive Kit for Immediate Use
Upon delivery, the ZT-702S comes with everything needed for immediate operation. The package includes the meter, a comprehensive English manual, standard test leads, a thermocouple probe, an oscilloscope probe with a 1/10 attenuator, a carrying case, and a USB-C to USB-A cable, ensuring users have all the necessary components for diverse measurement tasks
Technical Specifications
The ZT-702S excels with a display range of 9999 counts and a sampling rate of three measurements per second. It covers a wide range of voltage, current, resistance, and capacitance measurements with impressive accuracy. Its True-RMS measurement capability, data hold feature, and automatic range switching make it a highly reliable tool for professionals
Oscilloscope Functionality
In oscilloscope mode, the ZT-702S offers a bandwidth of 10 MHz with real-time sampling at 48 MSa/s. The device’s input coupling, impedance, sensitivity, and time base are highly adaptable, making it suitable for a variety of measurement needs. However, users should be aware of its limitations in accurately depicting signal shapes due to its 8-bit resolution ADC
Robust Internal Build and Easy Operation
The ZT-702S’s internal build is as impressive as its external features. The robust casing, reinforced with additional ribs, houses a large 18650-type lithium battery and a fully metal-shielded PCB for the oscilloscope’s preamplifier. The meter’s durability and reliability are evident in its design and manufacturing
Versatile Menu and Control Options
The oscilloscope mode offers a range of menu options and control functions, including voltage coupling, trigger mode selection, and measurement probe adjustments. These features, along with its easy-to-navigate menu and dual-function control buttons, make the ZT-702S a highly intuitive device, minimizing the need to frequently consult the manual
Final Thoughts
The ZT-702S Digital Oscilloscope is an epitome of ZOYI’s commitment to quality and innovation. While it excels in its multimeter capabilities, its oscilloscope function is suitable for general electronic measurements, offering an accessible tool for professionals in various industries. The ease of converting its display into exportable graphic files is a bonus for those needing to document their measurements and experiments
