Providing Power
Power for LabQuest Stream is supplied by the rechargeable lithium-ion battery
included with the unit. LabQuest Stream can also be powered without the battery
by the following methods:
Using the AC power adapter
Using the USB port of a computer or Chromebook
Using a USB power outlet or power adapter
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
having other devices that require USB power connected to the computer or
Chromebook at the same time. In these situations, we recommend you use the
battery or AC power adapter to provide power to LabQuest Stream.
Charging the LabQuest Stream battery
Use the supplied AC adapter, USB cable, or optional Charging Station
(order code LQ2-CRG) to charge the battery. The battery cannot be overcharged
and can be safely recharged after a partial discharge.
The Charging LED, , flashes red when the battery level is low. The LED is
orange when the battery is charging and green when the battery is fully charged.
For safety reasons, the charging circuitry on LabQuest Stream will turn offafter
about 10 hours, even if the battery is not fully charged. When this happens, the
charging LED will glow red. To continue charging the battery, disconnect then
immediately reconnect the power source.
3
The following are approximate time durations required to fully charge a dead
battery:
AC adapter: ~8 hours
Charging Station: ~8 hours
USB port: ~10 hours
Note: LabQuest Stream will not charge while connected via USB to a computer or
Chromebook that is in a suspended state.
Turning the unit on
Press the power button located on the top of LabQuest Stream to turn the unit on.
The Power LED,
, will be green when the unit is on. Note that the unit will
automatically turn on when it is connected to the USB port on a computer or
Chromebook.
Turning the unit off
Press and hold the power button for 3 seconds to turn the unit off. The
Power LED,
, will be off when the unit is off. LabQuest Stream will
automatically turn off after 10 minutes when not connected to a Bluetooth orUSB
host.
Connecting Sensors
LabQuest Stream supports two types of sensors—analog and digital. Connect
sensors to the appropriate port on LabQuest Stream.
Analog Sens ors
Analog sensor examples include temperature probes, pH sensors, and force sensors.
Up to three analog sensors can be connected to LabQuest Stream. 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.
DigitalSensors
Digital sensor examples include motion detectors, photogates, and rotary motion
sensors. Up to two digital sensors can be connected to LabQuest Stream. 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.
4
Note: Most sensors will automatically identify 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
Battery
LabQuest Stream 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.
Use the supplied AC adapter, USB cable, or optional Charging Station
(order code LQ2-CRG) to charge the battery. The battery takes 8 to 10 hoursto
fully charge. The battery cannot be overcharged, and it can be safely recharged
after a partial discharge. It is safe to leave the battery charging indefinitely, and
there is no need to fully discharge the battery before needing to charge it.
The discharge time for a fully charged battery will depend on the sensors used. In
most cases, you can obtain 24 or more hours of use before recharging. We
recommend charging LabQuest Stream overnight to start the next day with a full
charge.
6
The long-term life of the battery will vary, but you can expect about 500 full
charge/discharge cycles before the battery will need to be replaced. In this count, a
charge from half charged to a full charge counts as half of a charge cycle. In
typical school use, the battery can last three years or more. Exposure to
temperatures over 35°C (95°F) will significantly reduce battery life.
As a battery reaches the end of its functional life, the discharge time for a fully
charged battery will become shorter. Eventually the discharge time will betoo
short for your application, and you will want to replace the battery. Rechargeable
batteries are considered a consumable, and as such, are warranted for one year. A
replacement battery can be ordered from our website (order code LQ2-BAT).
Recycling information is available at
www.cal l2recycle.o rg
Use only the supplied battery for this device. Do not puncture or expose the
battery to excessive heat or flame.
Temperatur e c onside rations
Safe operating temperatures for LabQuest Stream are from 0°C to 45°C
(32°F to 113°F). Storage temperatures are –30°C to 60°C (–22°F to 140°F).
Exposures to low or high extreme temperatures will temporarily reduce the
discharge time for a fully charged battery. Exposure to temperatures over 35°C
(95°F) will significantly reduce long-term battery life.
Avoid rapid temperature changes as condensation may form inside the device. Do
not leave it in a car, as temperatures can exceed the maximum storage range.
Water Resistance
LabQuest Stream is not water resistant and should never be immersed in water. If
water gets in the device, immediately remove the USB cable and turn the unit off
by holding down the power button for at least 3 seconds. Disconnect all sensors
and cables and remove the battery. Allow the unit to dry thoroughly before
restarting it. Do not attempt to dry it using an external heat source.
Storage
Do not store LabQuest Stream in a chemical closet or in areas of concentrated
chemical gases.
Safe storage temperatures are –30°C to 60°C (–22°F to 140°F). Exposing the
battery to temperatures above 35°C (95°F) will reduce its lifespan. If possible, store
LabQuest Stream in an area that is not exposed to temperature extremes.
To store LabQuest Stream for extended periods of time, turn the unit off and
remove the battery. Over several months, the battery will discharge but will not be
damaged. After such storage, charge LabQuest Stream (a full charge can take
10 hours), and the unit will be ready for use.
How the Interface Works
The LabQuest Stream interface is more than just a physical adapter between two
differen t con ne ctors. It is hardware that al lows Verni er senso rs to interact with
computers, Chromebooks, and mobile devices. LabQuest Stream contains
dedicated electronics for precise sampling of sensor events. LabQuest Stream
timestamps these events so measurements from multiple sensors can be analyzed
7
simultaneously. To allow data to flow smoothly, LabQuest Stream manages the
communication link between the sensors and the computing platform.
