  • 25 000-count multimeter with 3.5-inch IPS display reads voltage, current, resistance, capacitance and frequency
  • ±400 V input range with CAT III 1000 V / CAT II 600 V safety ratings protects user and device
  • One-key automatic measurement and calibration speeds up routine testing

Compact 3-in-1 Test Instrument

The ZOYI ZT-703S combines a digital oscilloscope, signal generator and multimeter in a desktop chassis with a 3.5 inch IPS display. It targets engineers, technicians and hobbyists who need bench-top waveform capture, signal output and standard multimeter ranges in one unit.

Safety-Rated Inputs and Sampling

The oscilloscope channel accepts up to ±400 V input and is rated for CAT II 600 V, while the multimeter meets CAT III 1000 V. Real-time sampling reaches 280 MSa/s at 50 MHz bandwidth, and the 25000-count display resolves measurements without active cooling noise.

Automated Features and Data Tools

One-key automatic measurement runs calibration and captures readings without manual ranging. Users can save and export data, select interface languages, adjust backlight brightness and set a custom auto-shutdown timer. The ABS and TPE moulded housing meets CE requirements for bench durability.

Questions about this item

How do I connect the probes to the dual-channel 50MHz inputs and what step do users often skip?

Attach each probe to the BNC connectors for Channel 1 and Channel 2, then run the one-key automatic calibration before measuring; skipping this calibration is the common error.

Which parts of the ZT-703S will need periodic replacement?

The test leads and probe tips wear with use; the internal rechargeable battery will eventually hold less charge and should be swapped when run-time drops noticeably.

What is the first limit reached during continuous high-speed capture at 280MSa/s?

The 25000-count display resolution and 50MHz bandwidth constrain the visible detail before the sampling rate becomes the bottleneck.
