Product Features:
1. High-definition OLED display: 128×64 resolution for clear and intuitive measurement readings.
2. Simultaneous dual-channel voltage measurement allows for comparison of two voltage channels, making it suitable for integration into various compact devices.
3. Metal housing: Stainless steel casing with built-in mounting holes for easy screw fastening and interference resistance.
4. Three-wire/four-wire sampling with software calibration support ensures accurate and reliable voltage measurements.
5. Compact size and low power consumption, making it suitable for battery testing, power supply monitoring, and DIY device modifications.
6. Separate power supply and measurement circuits—the meter’s power supply is isolated from the voltage under test, making it suitable for DC circuit monitoring.
