Advanced measurement functions and practical possibilities
The ZT-703S multimeter is much more than a traditional meter – it's an advanced diagnostic tool that enables precise measurements of a wide range of electrical parameters. It measures DC/AC voltages up to 1000 V, currents up to 10 A, and resistances up to 250 MΩ , while offering high accuracy thanks to a resolution of 0.001 mV . Ranges can be changed automatically or manually , giving the user full control over the measurement process. Additional functions, such as capacitance measurement (up to 99.99 mF), frequency (up to 999.9 kHz), and diode and continuity testing , make the device a comprehensive measurement tool – ideal for working with power supplies , digital and analog circuits, and audio devices. It's worth noting that the ZT-703S also has a temperature measurement function up to 1000°C , making it a universal tool for both electronics technicians and household appliance service technicians.
The functionality of the multimeter covers a wide range of measurements.
The multimeter has a built-in 3.7 V lithium battery with a capacity of 2000 mAh, charged via the USB Type-C port.
Work comfort, data memory and computer integration
The ZT-703S is designed with user comfort and ease of use in a variety of conditions in mind. The 2.8-inch color IPS display offers four brightness levels (30%, 50%, 80%, 100%), ensuring excellent readability even in bright lighting or dark service areas. An intuitive English menu facilitates quick switching between modes and parameters, and the HOLD function freezes the measurement value, which is particularly useful in hard-to-reach areas. Thanks to the data storage option and the USB Type-C port, the device allows for transferring measurements to a computer , which is invaluable for laboratory work, documentation, or teaching. Additionally, the REL function (relative measurement) and automatic shutdown (15-120 minutes or manual shutdown) make this multimeter not only functional but also energy-efficient and safe.
