    ASA100 User Manual Introduction Welcome Congratulations and thank you for purchasing an Electron Plus product. Please take a few minutes to read the ‘Before you start’ section of this manual, especially as misusing this product can result in damage to it, your device-under-test or potentially place you in-danger.

  • Page 12: Before You Start

    ASA100 User Manual Before you start Please use the supplied USB lead - it have been tested to work with your ASA100. Thin USB cables tend to exhibit higher resistance which may cause in-correct operation of your device. Ensure that all DUT* capacitors and energy storage devices are fully discharged before using the ASA100.
