Cycle Power


Performing a power cycle on an SDL data logger such as the X2-SDL is often useful for troubleshooting purposes.

To cycle power on an SDL:

  1. Locate the white battery lid at the top of the SDL.
  2. Rotate the cap counter-clockwise to remove it.
    1. Note: Due to the double O-ring lid seal, this will take significant effort to loosen.
    2. The 3/16″ ball-point hex driver included in the SDL maintenance kit can be inserted into either of the two recesses in the lid to provide extra leverage.

  1. Wait approximately 60 seconds to allow residual power in the system to discharge fully.
  2. Thread the battery lid back onto the top bulkhead of the SDL.
    1. Rotate the lid clockwise and tighten securely using the hex driver.
  3. Once the large washer at the bottom of the white battery lid makes contact with the battery terminals, power will be applied to the SDL.
    1. For X2-SDL or SDL-V2 data logger models, a buzzer will emit a sound when power is applied.
