LabQuest Mini User Manual

LabQuest Mini

LabQuest Mini is a multi-channel, data-collection interface that can be used to collect data from Vernier sensors on various platforms, such as Windows® and Mac® computers and Chromebooks™. LabQuest Mini supports a wired (USB) connection only.

The LabQuest Mini interface contains three analog ports (CH 1–CH 3), two digital ports (DIG 1 and DIG 2), a mini-USB connection, and a power adapter port (although power through this port is rarely needed).

 

Note: Vernier products are designed for educational use. Our products are not designed, nor are they recommended, for any industrial, medical, or commercial process such as life support, patient diagnosis, control of a manufacturing process, or industrial testing of any kind.

What's Included

  • LabQuest Mini interface
  • USB cable

Getting Started

Follow these general procedures when using LabQuest Mini. For instructions on getting started with a specific sensor, www.vernier.com/start/lq-mini

  1. Install software appropriate for the data-collection platform you are using.
  2. Connect a supported sensor to LabQuest Mini.
  3. Connect the small end of the USB cable to the USB port on LabQuest Mini.
  4. Connect the other end of the cable to a USB port on your computer or Chromebook. The LED will glow orange.
  5. Start the software. The LED will change to green. You are now ready to continue your experiment.

Supported Sensors

Compatibility Notes

  1. Requires a Motion Detector Cable to connect to a DIG port on the interface
  2. Requires a BNC electrode
  3. Data can be collected using the sensor’s default calibration. Future software updates will support calibration modifications.
  4. This software cannot apply digital filters to EKG data.
  5. Software does not support the Data Tagging feature that is typically used with this sensor.
  6. Requires an additional signal source, such as LabQuest 2 running the Power Amplifier app or a computer running the Power Amplifier Function Generator Software, to control the Power Amplifier output
  7. Software cannot calculate resistance or power data.
  8. This interface/software combination can only collect force data; displacement measurements are not supported.

Providing Power

Power for LabQuest Mini is supplied by the USB port of the computer or Chromebook to which it is connected. LabQuest Mini does not need batteries or an external AC power supply.

Note: There may be configurations that limit how much power is available from the USB port on a computer or Chromebook. Such configurations may include the use of other devices that require USB power at the same time as LabQuest Mini. In these situations, disconnect the other devices or use an external power supply (order code LQ-PS) to provide additional power to LabQuest Mini.

Connecting Sensors

Connecting Sensors

LabQuest Mini supports two types of sensors—analog and digital. Connect sensors to the appropriate port on your LabQuest Mini.

Analog Sensors

Examples of analog sensors are temperature probes, pH sensors, and force sensors. Up to three analog sensors can be connected to LabQuest Mini. The three ports for analog sensors (CH 1–CH 3) are located on the left side of the unit. These ports accept British Telecom-style plugs with a right-hand connector.

Digital Sensors

Examples of digital sensors include motion detectors, photogates, and rotary motion sensors. Up to two digital sensors can be connected to LabQuest Mini. The two ports for digital sensors (DIG 1 and DIG 2) are located on the top side of the unit. These ports accept British Telecom-style plugs with a left-hand connector.

Note: Most sensors are automatically identified allowing the software to set up a default experiment. If you are using a sensor that does not auto-ID, you will need to manually identify the sensor in the software.

Care and Maintenance

Water Resistance

LabQuest Mini is not water resistant and should never be immersed in water. If water gets in the device, immediately disconnect all sensors and cables. Allow the unit to dry thoroughly before using it again. Do not attempt to dry it using an external heat source.

Storage

Do not store LabQuest Mini in a chemical closet or in areas of concentrated chemical gases.

How the Interface Works

The LabQuest Mini interface is more than just a physical adapter between two different connectors. It is hardware that allows Vernier sensors to interact with computers and Chromebooks. LabQuest Mini contains dedicated electronics for precise sampling of sensor events. LabQuest Mini timestamps these events so measurements from multiple sensors can be analyzed simultaneously. To allow data to flow smoothly, LabQuest Mini manages the communication link between the sensors and the computing platform.
