I.
Getting Started with LabQuest 2 LabQuest uses a high-quality lithium-ion battery. This is the same chemistry used in premium laptop and cell phone batteries, and you can expect similar performance. There is never a need to condition the battery by regular full discharge/charge cycles. It is safe to leave the battery charging indefinitely, and there is no need to fully discharge the battery before charging.
Getting Started with LabQuest 2 4. Tap the graph to examine a point of interest. The coordinates of the point are shown in the panel to the right of the graph. Tap another point or tap the Examine buttons to move the cursor left and right . 5. To select a region of data for analysis, tap-and-drag across the graph to highlight the desired region. Note: To analyze all data, you do not need to select a region.
II. LABQUEST 2 HARDWARE Once LabQuest is connected to AC power or the battery has been charged, press the power button located on the top of the unit, near the left edge. LabQuest will complete its booting procedure and automatically launch the LabQuest App by default, as shown above. If the screen does not light after a moment when used on battery power, connect the power adapter to LabQuest and to an AC power source, then try the power button again.
LabQuest 2 Hardware Touch Screen LabQuest has an LED backlit resistive touch screen that quickly responds to pressure exerted on the screen. LabQuest is controlled primarily by touching the screen. The software is designed to be finger-friendly. In some situations, you may desire more control for precise navigation. In such cases, we recommend using the included stylus.
LabQuest 2 Hardware Audio ports are also located adjacent to the digital ports, as well as a microSD card slot for expanding disk storage. On the side opposite of the analog ports, there is a stylus storage slot, an AC power port for recharging the battery, and a mini USB port for connecting LabQuest to a computer. In between these ports, there is a serial connection for charging the unit in a LabQuest 2 Charging Station (order code LQ2-CRG, sold separately) and a stylus tether attachment point.
LabQuest 2 Hardware Internal Sensors LabQuest also has several built-in sensors, including a GPS, microphone, three-axis accelerometer, temperature sensor, and relative light sensor. To enable internal sensors within LabQuest App, choose Sensor Setup from the Sensors menu. Within the Sensor Setup dialog box, select a check box to enable the associated sensor. Then tap OK to return to the LabQuest App Meter screen.
LabQuest 2 Hardware • Microphone – The internal Microphone is located on the front of LabQuest to the left of the screen, as shown below, and measures waveforms. Note: This sensor cannot be used with external sensors.
III. LABQUEST APP The data-collection and analysis software, LabQuest App, is the heart of LabQuest. When you turn on LabQuest, the LabQuest App starts automatically. If the LabQuest App is not displayed on your screen, launch LabQuest App from the Home screen. Navigating LabQuest App LabQuest App has five different screens. Tap on the desired tab to display the associated screen. LabQuest App – Set up sensors, set datacollection parameters, and see a digital meter for your connected sensors.

LabQuest App number of samples could lead to performance issues. You can still collect data using these settings; however, you may have undesirable results.
LabQuest App can be used to mark points of interest during a timebased data collection. When enabled, a Mark Data button will appear during data collection. Tap to mark that particular point as a point of interest. After completing data collection, data marks can be named using the panel to the right of the graph. Data Marking o Mode: Events with Entry – Sometimes experiments depend on a quantity other than time.
LabQuest App two events. Choose the proper Photogate Mode for your experiment. For more information, see www.vernier.com/til/1623/ o Mode: Full Spectrum – When a spectrometer is detected, LabQuest enters the Full Spectrum mode. In this mode, Intensity, Absorbance, Fluorescence (SpectroVis Plus only), or %Transmittance can be measured as a function of wavelength. Detailed instructions for setting up data collection with spectrometers are included in each of our spectrometer labs.
LabQuest App • – Choose WDSS Setup from the Sensors menu to scan for, select, and configure Wireless Dynamics Sensor Systems. Turn on the WDSS and note its name. Tap Scan to create a list of available WDSS devices. The scan may take 20 to 30 seconds and may have to be repeated several times to find your particular WDSS. Once a scan has found your WDSS, select its name in the list, then tap OK. WDSS Setup Select the check box(es) to enable the sensor(s) you want to use. Tap OK to complete the setup.
LabQuest App • – To control how the data are graphed, choose Graph Options from the Graph menu. Here you can choose the columns used for the x- and y-axes and the axes limits. See Adjusting the Graph View for more information. Graph Options Select Autoscale to adjust to the data range after data collection ends. Autoscale from 0 does the same, but includes the origin. Manual scaling will respect values entered in the range limits, unless incoming data falls outside the range.
LabQuest App fine adjustments to the cursor location by using the Left Examine Button Examine Button located on either side of the horizontal-axis label. and Right In some cases, you may want to examine data for a particular region on the graph. To select a portion for analysis, tap and drag across the desired region. You can adjust the trailing endpoint of the selected region using the Examine Buttons, if needed. For greater control, you can opt to use the stylus.
LabQuest App Collecting multiple runs • – You can collect several runs for comparison. Choose Store Run from the Graph menu to save the current run and proceed with data collection. As a shortcut, tap the File Cabinet . Store Run To collect another run, tap Collect. Your new run is displayed on the graph. To see your first run, tap the Run 2 button to the left of the Filing Cabinet, and select either Run 1 or All Runs.
LabQuest App • Integral • Statistics • Delta – • Curve Fit – The Integral tool numerically integrates graphed data. Select a region, if needed, and choose Integral from the Analyze menu.
