    (e.g. sandbags, blocks, etc) to prevent the legs from moving or tipping over. SENSIT is not liable for damage due to improper tripod mounting. 4. Screw in earth anchor in the center of tripod footprint and thread ratcheting rope through anchor as shown.

  • Page 24: Anemometer (If Installed)

    ANEMOMETER (IF INSTALLED) 1. When installing the unit, ensure the alignment notch of the weather sensor is pointing North (see im- age below). Failure to do this will result in error in the wind direction measured by the anemometer. The North direction is indicated with a notch on the ultrasonic anemometer base. Never rotate the anemometer from the top or severe damage will occur.

    HARDWARE AND SOFTWARE INSTALLATION GUIDE FOR USB CABLE 1. Download drivers for FTDI Serial Adapter and install drivers https://gasleaksensors.com/products/sensit-spod/ (located in Downloads tab) 2. Open serial terminal program of your choice. CoolTerm is recommended and instructions for using CoolTerm are found below. CoolTerm is available for Windows, Mac, and Linux. CoolTerm can be downloaded for free from here: https://gasleaksensors.com/products/sensit-spod/...
  • Page 46 b. Select ‘Terminal’ options from list of available options and select ‘Line Mode’ as shown below. Line mode adds a text entry bar at the bottom of the screen that is useful for sending commands to the connected sensor. c. Select ‘Receive’ options from list of available options and check “Ignore Receive Signal Errors”. Selecting this option reduces the possibility of the serial connection closing upon a received serial error such as connecting or disconnecting the cable or power cycling the unit.
  • Page 47 b. Click “Save As Default” to change these settings to the default settings when starting the program. If you are running off the CD this option will give you an error as there is no default file. 5. Coolterm can be configured to record all data received over serial. This will be useful for evaluation pur- poses.
