ZOYI ZT-702S Handheld Oscilloscope and True RMS Multimeter
Combine portable waveform analysis with 9999-count multimeter measurement for electronics repair, field diagnostics, automotive testing and circuit development.
Waveform Analysis and Electrical Measurement
The ZOYI ZT-702S is a portable diagnostic instrument that combines a digital oscilloscope and a True RMS digital multimeter in one compact device.
Designed for electronics technicians, engineers, repair professionals and advanced hobbyists, it allows users to view changing electrical signals and perform standard multimeter measurements without carrying two separate instruments.
A practical diagnostic workflow: Use the oscilloscope to observe waveform shape, timing, noise or distortion, then switch to the multimeter functions for detailed voltage, current, resistance and continuity measurements.
Portable Oscilloscope Functions
Oscilloscope mode provides a visual display of AC and DC waveforms, helping users investigate signal behaviour that cannot be understood from a numerical multimeter reading alone.
PWM Signals
Inspect pulse-width-modulated control signals and switching behaviour.
Sensors
Observe changing sensor outputs during testing and fault diagnosis.
Microcontrollers
View outputs from Arduino boards, controllers and development circuits.
Power Circuits
Investigate switching activity, ripple and signal irregularities.
Audio Signals
Examine waveform shape, clipping, noise and distortion.
Automotive Electronics
Inspect compatible sensor, actuator and control signals.
9999-Count Multimeter Functions
- AC/DC voltage measurement
- AC/DC current testing
- Resistance measurement
- Continuity checking
- Frequency and duty cycle measurement
- Diode testing
- 9999-count display for clear numerical readings
True RMS measurement: True RMS technology supports dependable AC readings on non-linear and distorted signals produced by LED drivers, switching power supplies, inverters and variable-speed control systems, within the instrument’s specified limits.
Designed for Mobile Diagnostics
The clear colour display provides good contrast for waveform viewing, while the compact and ergonomic housing makes the ZT-702S suitable for field service, workshop benches, educational laboratories and locations where a full-size oscilloscope may be inconvenient.
Recommended Applications
- Electronics repair and PCB diagnostics
- Field engineering and mobile service
- Compatible automotive sensor and control-signal analysis
- Power-supply and PWM circuit inspection
- Arduino and microcontroller development
- Audio and general signal troubleshooting
- Educational laboratories and technical training
Important testing guidance: Oscilloscope and multimeter inputs may have different voltage and category limits. Check the user manual, use correctly rated probes and connect the oscilloscope reference lead only to an appropriate circuit point. Never exceed the marked input ratings.
