The A9 waveform multi-function measurement meter is designed for accurate and stable voltage and current sampling. It delivers high precision readings suitable for laboratory testing, electronic development, maintenance, and industrial monitoring Supports real-time voltage and current measurement with fast response and low deviation. Ideal for checking power supplies, circuit boards, and various electronic devices that require reliable test data Built-in waveform display function allows you to visually observe changes in voltage and current over time. This helps in circuit debugging, fault detection, and performance analysis with clear and intuitive data presentation Compatible with PC host computer software for screen recording and data capture. Users can record waveform changes, test procedures, and key measurement results in real time for review, sharing, and report creation (The product printed words may vary depending on the batch, but this does not affect use) Color: As Shown Material: plastic Package Contents: 1*Waveform Measurement Meter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
