Description:

The 703s is a dual-channel handheld device that integrates oscilloscope, multimeter, and signal generator functions. It features a 3.5-inch IPS display, 50 MHz bandwidth, 280 MSa/s fast real-time sampling rate, ±400 V input capability, 25,000 counts, 128Kb recording depth, and supports switching between oscilloscope, multimeter, and signal generator modes. It is easy to use and improves work efficiency.

The dual-channel handheld oscilloscope offers 50MHz bandwidth, 280MSa/s real-time sampling rate, 128kb recording depth, ±400V maximum measurement voltage, automatic measurement function, auto/normal/single trigger function, vertical sensitivity of 20mv/div-10v/div, and supports waveform image storage and export.

With 25,000 counts, it measures AC voltage: 0-750V; DC voltage: 0-1000.0V; DC/AC current: 0-10.000A; resistance: 0-250.0MΩ; capacitance: 0-99.99mF; frequency: 0-999.9kHZ; and includes diode and continuity testing. This multifunctional measuring instrument is ideal for professionals, factories, schools, hobbyists, and home use.

The device is built with a double-injection molded ABS and TPE reinforced structure, offering excellent impact resistance and durability. It has a 320*240 resolution, large font design for easy data reading, and adjustable brightness, making it suitable for various measurements in complex environments. It also includes a signal generator function capable of outputting six types of waveforms: sine, square, triangle, full wave, and half wave.

Equipped with a built-in 3400mAh rechargeable lithium battery, it provides up to 8 hours of standby time. The charging and data transmission share a Type-C interface, allowing use while charging. It features three trigger modes: auto, normal (continuous), and single. Additional functionalities include intelligent anti-burnout, switchable automatic and manual measurements, auto-shutdown, adjustable Chinese and English language settings, low battery warning, and supports PC transmission for waveform storage and viewing.
