Scope of Application
Cell phone speakers, receivers, MP3, tablet PC, laptop PC speakers, low power TV speakers, etc.
Performance Characteristics
- Signal source: built-in sine wave generator and sweep controller, can be stored in various formats of audio files
- Two groups of voltage can be arbitrarily set 20-way simultaneous monitoring, automatic recording and display of voltage/current/DCR/temperature rise/test time and status
- Automatic calibration of test voltage, accuracy up to ≤1%, display 0.001V
- Panel 8 inch LCD, display content is richer, larger font, easy to observe
- Interface: Front panel signal data input interface (USB), rear panel USB, LAN network port
- Temperature rise measurement range: 0~200℃, measurement accuracy≤5%±1℃.
- Support multiple working modes: continuous, gap, debugging. One of the small intermittent support 0.5s, and can still accurately measure the voltage
