  • Page 19 2. Hook any valves and pressure sensors up to the valve/pressure ports. 3. Power on SPOD and configure sampler as described in the USB configuration settings. Please note that when enabling sampling for the first time, the user must power cycle before attempting to configure the sampler parameters.
  • Page 20 LED COLOR DESCRIPTION BLUE Not Enabled GREEN Enabled and Not Collected Enabled and Collected RED-GREEN-BLUE Currently Collecting Sample 5. The canister valve controller features 4 local buttons for control and testing. The button behavior will depend on the status of port. When the button is pushed, the LED begins to flash RED-GREEN-RED- GREEN.
  • Page 21 7. The connection to the canister is shown here both with and without a pressure sensor and no manifold. The inlet of the valve should be the high pressure (atmosphere) side and the outlet of the valve should be the low pressure (vacuum) side of the valve. 8.

DEFAULT: Resets all options to the factory default. Not recommended without consulting SENSIT. This will remove all custom settings including cellular information. DISPLAY: Displays all current settings in the terminal window.
  • Page 24 “USERPASS” or “AZUREHUB”. To manually configure username and password type “USERPASS”. If using Azure IoT hub, type “AZUREHUB” to send SAS token. The SPOD will parse the relevant connection parameters from the SAS token.

For TLS authentication the user must load a root certificate file for the server on the microSD card. Prior to version 6.00 it was necessary to load a certificate file on the SD prior to enabling TLS.
  • Page 27 ODR: Sets the output data rate of the cellular modem or XBEE wireless device. The USB port will always show data output at 1Hz POLL: Disable streaming over USB/Port and XBEE. SPOD will return data when receiving any character from control device.

  • Page 29 This requires a 12V valve and is switched with a 3.3V digital output. Valve must be isolated from SPOD. “NONE” is no sampler hooked up. This should be selected if not using a sampler to avoid and initialization error upon startup. “PRESSURE” is configured to allow the valve controller to hook up a pressure sensor to monitor canister pressure and stop sampling at a predefined threshold (-2.5 PSI) and is only relevant for deployments with pressure sensors.
  • Page 30 If RAW readings are used the threshold will be in mV and if PPB readings are used the threshold will be in ppb. Finally, the SPOD will prompt the user to select a STATIC or DYNAMIC threshold. If a STATIC threshold is selected, the trigger level is absolute with respect to zero. If DYNAMIC threshold is selected, the trigger threshold is with respect the background concentration over a user selectable period ranging from 10 –...
  • Page 31 SPOD when plugging in the cable. 2. Hook up the flowing zero air to the SPOD using the SPOD calibration cap. 300-500 sccm is preferred. Moderately higher flow rates (up to 1000 sccm) should work fine, but lower flow rates are not recom- mended.
  • Page 32 3. If zeroing, press and hold the black switch until the calibration LED starts flashing 1 time per second and release the switch. The SPOD will now run for a minimum of 1 minute up to 3 minutes waiting for the reading to stabilize. At the end of this time the calibration LED will stop flashing. For firmware...
