    4. Remove the charging cable and place the protective cap back onto the probe. Firmly press down to engage the O-ring (and ensure the sealing). Once engaged, screw the cap by slowly turning clockwise until the cap is fully screwed on. Firmly press the Turn the cap cap downwards...
  • Page 22 Flip the probe straight, and manually switch off the probe (the LED will no-longer be flashing). Partially place the control lid back on (you only need to screw a few threads for the lid to hold in place). Hold the main body of the probe tight and unscrew the battery lid off (be gentle and do not pull too much on the battery cables).
  • Page 23 Flip the probe up-side down, and partially lift the orange tape just enough to see where the battery is connected. Press on the battery connector pin (use a tool or nails as necessary) while pulling the connector off at the same time. Lift the battery all the way and remove the battery.
  • Page 24 To install the new battery, make sure the male connector faces the connector head before placing the battery into the probe (the battery should be placed exactly with the same orientation as before and it should fully align with the cable). Partially hold the battery using the orange tape just enough to connect the battery connector.
  • Page 25 Lower down the battery and tidy up the 2 cables (gently press the cables in each corner, the cables should lie flat with the other cables). Screw the battery lid on until it is tight. Always visually make sure there is no gap left. Manual | NEP-695 Page 25 | 51 Status: Final | Not confidential...

  • Page 26: Led Indicators

    Flip the probe straight, unscrew the control lid and manually switch on the probe. Screw the control lid onto the probe until it is tight. Always visually make sure there is no gap left. Check the LED status, if the red LED is flashing on every 10 seconds, it means that the probe is logging.

  • Page 27: Maintenance & Storage

    7.4 Maintenance & storage It is strongly recommended that the logging probe be thoroughly washed in clean water after deployment and prior to storage. In the field, wash the probe with fresh water and clean it with a soft cloth. In the office, we recommend to clean the sensor with fresh water and dry the sensor with compressed air.
