ZOYI ZT-706S 3-in-1 Handheld Oscilloscope Multimeter
Measure electrical values, compare two waveforms and generate test signals with one portable instrument combining a 50MHz dual-channel oscilloscope, 66,000-count True RMS multimeter and signal generator.
Three Professional Test Tools in One
The ZOYI ZT-706S is designed for technicians, engineers and repair specialists who need advanced diagnostic functions in a portable format. It reduces the need to carry separate instruments and allows users to switch between waveform analysis, electrical measurement and signal generation.
Dual-Channel Oscilloscope
50MHz bandwidth with real-time sampling up to 280MSa/s for waveform comparison and signal analysis.
True RMS Multimeter
66,000-count display with AC/DC voltage, current, resistance, capacitance and frequency measurement.
Signal Generator
Six waveform types with adjustable frequency, amplitude and duty cycle for compatible circuit testing.
A complete diagnostic workflow: Generate a test signal, compare circuit input and output waveforms on two channels, and use the integrated multimeter to confirm electrical values—all with one handheld instrument.
50MHz Dual-Channel Oscilloscope
The two oscilloscope channels allow users to display and compare separate signals, inspect timing relationships and investigate intermittent circuit faults. Normal mode provides sampling up to 200MSa/s, while high-speed mode increases the rate to 280MSa/s for signals above 30MHz.
One-key AUTO setup helps stabilise unfamiliar waveforms quickly. Auto, Normal and Single trigger modes are available with rising-edge and falling-edge triggering.
- 50MHz oscilloscope bandwidth
- Two inputs: CH1 and CH2
- 10ns/div to 20s/div time base
- 20mV/div to 10V/div vertical sensitivity at ×1
- AC and DC input coupling
- ×1 and ×10 probe settings
- Y-T, XY and Roll display modes
- FFT spectrum, persistence and cursor measurement
- Vpp, maximum, minimum, RMS, frequency, period and duty-cycle readings
66,000-Count True RMS Multimeter
The integrated digital multimeter provides detailed measurements for electronics repair, equipment maintenance and compatible electrical testing. Both automatic and manual range selection are supported.
AC/DC Voltage
Measure DC voltage up to 1000V and AC voltage up to 750V.
AC/DC Current
Current measurement up to 10A within the instrument’s rated limits.
Resistance and Capacitance
Measure resistance up to 66MΩ and capacitance up to 99.99mF.
Frequency
Multimeter frequency measurement up to 99.99kHz.
Continuity and Diodes
Check wiring paths, electrical connections and compatible diodes.
Advanced Functions
MAX, MIN, AVG, Data Hold, relative measurement and VFC filtering.
True RMS and VFC: True RMS supports dependable readings on distorted AC signals, while VFC filtering can improve measurement stability in electrically noisy environments such as inverter and variable-frequency control systems.
Built-In Multi-Waveform Signal Generator
Generate standard test signals without carrying a separate function generator. Frequency, amplitude and duty cycle can be adjusted directly from the instrument for compatible circuit-development and troubleshooting tasks.
