WPI EVOM Quick start guide

  • Hello! I'm here to assist you with the TEER Meter Manual. I've reviewed the Quick Start Guide, which covers device setup, voltage and resistance measurements, data storage, and electrode calibration. Feel free to ask me any questions about configuring measurements or operating the device. The document also details how to handle data transfer via USB and electrode equilibration.
  • How do I power on the device?
    How do I store data files?
    How do I perform resistance measurements?
    What if the USB drive is not recognized?
