Go Direct sensors running older firmware should be updated. While sensors with older firmware will work with Graphical Analysis and LabQuest App, there will be differences in software features and behavior compared to sensors running the newest firmware.

Determine if your sensor needs a firmware update using Graphical Analysis
     1. Launch Graphical Analysis .
     2. Connect your sensor and look for firmware update information. If connecting the sensor initially by USB, click the Sensor Setup button at lower left:

Determine if your sensor needs a firmware update using LabQuest App (v2.8.5 or newer)
     1. Connect your sensor via wireless or USB connection.
     2. Once connected, a dialog will be shown when a firmware update is available for that sensor. You cannot update the sensor firmware from a LabQuest.

Update the Firmware
You must use a computer or Chromebook running Graphical Analysis to update firmware.
     1. Launch the most recent version of the Graphical Analysis app on a computer or Chromebook.
     2. Connect the sensor to the computer or Chromebook via USB. You cannot update sensors with a Bluetooth connection.
     3. Click or tap the Sensor Setup button (lower right corner of the screen) to launch the Sensors dialog.
     4. Click or tap the Update Firmware button under the sensor you want to update.
     5. Click or tap the Close App and Update Firmware button.
     6. When the update is complete, click or tap the Return to Graphical Analysis button. Your sensor is now updated.

Do not use a virtual machine such as VMWare on a Mac while updating the firmware. Updates will fail if a virtual machine is running. Only use Graphical Analysis on the host operating system for firmware updates, and shut down or pause any virtual machines before starting firmware updates.
