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.
If you are having trouble viewing the color screen or are using LabQuest outside in bright
sunlight, we recommend changing to the High Contrast mode. Tap Preferences on the Home
screen, then tap Light & Power. Select the check box for High Contrast
to enable this mode.
Hardware Keys
In addition to using the touch screen, the three hardware keys can also be used to control your
LabQuest.
•
Collect – Start and stop data collection within LabQuest App
•
Home – Launch the Home screen
•
Escape – Close most applications, menus, and exit dialog boxes without taking action
(i.e., cancel dialog boxes)
Sensor Ports
LabQuest has three analog sensor ports (CH 1, CH 2, and CH 3) for analog sensors such as our
pH Sensor, Temperature Probe, and Force Sensor. Also included is a full-size USB port for USB
sensors, USB flash drives, and USB printers. In addition to the power button, the top edge of
LabQuest has two digital sensor ports (DIG 1 and DIG 2) for Motion Detectors, Drop Counters,
and other digital sensors.
