LabQuest Stream Sensor Setup

LabQuest Stream is a multi-channel interface that connects to your computer directly via USB or wirelessly via Bluetooth^®. Connect via USB if you are collecting at very high data-collection rates or collecting data over long periods of time. Connect via Bluetooth if it is required or beneficial for your experimental setup. For example, connecting via Bluetooth allows you to keep your computer further away from the water's edge during water quality testing.

Follow these steps to collect data with LabQuest Stream:

Connect via USB

1. Connect LabQuest Stream to the USB port on your computer running Logger Pro. Note: The Bluetooth radio on LabQuest Stream will automatically turn off when LabQuest Stream is connected via USB to a computer.
2. Connect a sensor to LabQuest Stream.
3. If auto-ID sensors are found, live readings will be displayed on the screen. If a LabQuest Stream is found but your sensors are not identified, you should manually set up a sensor or open an appropriate experiment file.
4. To start collecting data, click Collect . You can stop data collection at any time by clicking Stop .

Connect via Bluetooth

To collect data via Bluetooth, you must A) pair your LabQuest Stream with your computer and B) connect to LabQuest Stream in Logger Pro. Note: If you have not changed the name of your LabQuest Stream it will be identified by its serial number (found on the bottom of the device).

Part A: Pair LabQuest Stream with Your Computer

Tip: If you have used this LabQuest Stream with this computer, skip to Part B. If you are unsure continue with this Part.

1. Press the power button on LabQuest Stream to turn it on.
2. Pair LabQuest Stream with your computer:

macOS: Open System Settings, navigate to the Bluetooth settings, and pair with LabQuest Stream.

Windows: Open the Settings dialog for Windows, navigate to the Bluetooth settings, and pair with LabQuest Stream.

Troubleshooting

• Verify that your LabQuest Stream is on (green LED is on) and the Bluetooth on LabQuest Stream is working (blue LED is flashing).
• Ensure you connect to the correct LabQuest Stream by verifying the serial number
• As each operating system has its own pairing procedure, please see help for your computer if you need more information about how to pair.

3. Once LabQuest Steam has been paired with your computer, return to Logger Pro.

Part B: Connect to LabQuest Stream in Logger Pro

1. Turn on LabQuest Stream if it is not already on (green LED for power is on).
2. From the Logger Pro Experiment menu, choose Connect Interface > Wireless LabQuest Stream > Scan for Wireless LabQuest Stream.
3. If your LabQuest Stream appears in the list, select your device and click Connect. Note: Verify the serial number; it can be easy to connect to the wrong interface in a classroom with multiple devices.
• Logger Pro will connect to LabQuest Stream and you are ready to connect a sensor and click Collect or open an experiment file.
• If you don't see your LabQuest Steam in the list, verify LabQuest Stream is on (green LED is on) and LabQuest Stream Bluetooth is working (blue LED is flashing). Then, click Rescan. Continue with the next step if LabQuest Stream does not appear in the list of available devices after rescanning.
4. If Logger Pro can't find LabQuest Stream, the first troubleshooting step is to re-pair LabQuest Stream with your computer.

macOS

1. Click Open Bluetooth Preferences, and pair the device. See Part A for troubleshooting.
2. Once LabQuest Steam has been paired with your computer, return to Logger Pro and choose Connect Interface > Wireless LabQuest Stream > Scan for Wireless LabQuest Stream from the Experiment menu.
3. Select your device from the list and click Connect.

Windows

1. Open Bluetooth settings from the Windows Settings dialog, and pair LabQuest Stream with your computer. See Part A for troubleshooting.
2. Once LabQuest Steam has been paired with your computer, return to Logger Pro and click Retry. Logger Pro will connect to LabQuest Stream and you are ready to connect a sensor and start data collection or open an experiment file.

Additional Troubleshooting

1. LabQuest Stream will go to sleep to conserve battery power, so first, verify that LabQuest Stream is on (green LED is on) and that the Bluetooth on LabQuest Stream is working (blue LED is flashing).
2. Verify that your computer's Bluetooth is turned on.
3. In a classroom with multiple interfaces, it can be easy to pair with the wrong LabQuest Stream or connect to someone else's interface in Logger Pro. Verify that the serial number on the back of the LabQuest Stream matches the serial number of the device that is paired with your computer.

LabQuest Stream Sensor Setup Options

You can open the LabQuest Stream Sensor Setup dialog by clicking the LabQuest Stream icon, , in the toolbar.

A window will appear showing the sensor setup, units, and current readings (if Live Readouts in the Column Options dialog is checked). Here you can manually make changes to your sensor setup.

By clicking a channel with a displayed sensor, you can change the settings for the sensors that can be connected to LabQuest Stream.

• Calibrate... Calibrate the sensor. This option will only be available if the sensor can be calibrated (some sensors, such as EKG sensors, cannot be calibrated).
  
  
• Sensor Info... Find the Typical Sample Rate and Maximum data-collection rate for the sensor.
  
  
• Zero Zero the sensor. This option will only be available if the sensor can be zeroed. Some sensors, including Temperature Probes, cannot be zeroed.
  
  
• Choose Sensor Manually set up a sensor in the channel.
  
  
• Change the Current Settings Select from the available units or calibration settings.
