Using the Lab Cradle with a Computer

The Lab Cradle works with all Windows® and Mac® operating systems currently

supported by the TI-Nspire™ Teacher and Student computer software.

Using the Lab Cradle as a Stand-Alone Data Collection Tool

You can use the Lab Cradle in stand-alone mode to collect data either manually or

automatically. Press the trigger button to manually start and stop data collection when

in stand-alone mode.

Note: For long-term data collections TI recommends you use an AC adapter for a

handheld or a remote collection device such as the Lab Cradle.

Before collecting data, set up the data collection parameters using the Vernier

DataQuest™ app or use the sensor’s default settings. If you do not change the

parameters and use a single sensor, the Lab Cradle collects data using the sensor’s

default settings. If you use multiple sensors, the Lab Cradle collects samples beginning

with the sensor that has the shortest collection time requirement.

You do not have to reconnect the Lab Cradle to the same computer or handheld to

download the data. You can use any computer or handheld running a compatible OS

and TI-Nspire™ software to download the data.

Learning About the Lab Cradle

Portability

The Lab Cradle fits into the palm of most high school students' hands when connected

to the TI-Nspire™ handheld.

The Lab Cradle features an attachment point for a lanyard. Students can attach a

lanyard to wear the Lab Cradle around their neck. This feature lets students keep their

hands free to steady themselves in rough terrain during remote data collection

activities.

When collecting data for an experiment that subjects the Lab Cradle to intense

movement, TI recommends that students wear a Vernier Data Vest or zip-up jacket

with the sensor secured both around the student’s neck as well as to the student’s

TI-Nspire™ Lab Cradle 61

62 TI-Nspire™ Lab Cradle

chest. For example, if a student is measuring speed or motion on a roller coaster, the

Lab Cradle may bounce around due to the movement of the roller coaster. Wearing a

zip-up jacket or Vernier Data Vest limits the movement of the Lab Cradle.

Durability

The Lab Cradle is durable enough to withstand extensive use in the classroom and in

the field. It is designed to survive being dropped from a height of 36 inches, the height

of a standard lab table.

Storing/Operating Temperature Ranges

The Lab Cradle storage temperature range is between -40°C (-40° F) to 70°C (158° F).

The Lab Cradle, when used as a stand-alone data collection tool, operates in

temperatures from 10° C (50° F) to 45° C (113° F).

Triggering Methods

The Lab Cradle has two options for triggering data collection—automatic or manual.

To use automatic triggering, define the criteria in the Vernier DataQuest™ application

to start data collection. The Lab Cradle can trigger on either an increasing or

decreasing value.

Manual triggering is defined in the Vernier DataQuest™ app. By setting the trigger

delay value to zero, you can start data collection by pressing the trigger button on the

Lab Cradle when using it as a stand-alone data collection tool.

You can define a delay in triggering the data collection when using the Lab Cradle with

a computer or handheld. The Vernier DataQuest™ app starts a countdown based on the

time delay you define. When the countdown reaches zero, the Lab Cradle and its

connected sensors begin collecting data.

Multi-Channel Data Collection

You can connect up to five sensors to the Lab Cradle. It provides three analog BT

connectors and two digital BT connectors.

The Lab Cradle supports multi-channel data collection by allowing you to collect data

through all five sensors at the same time. When using all five sensors at the same

time, the time stamp is the same for all data collection streams.

Sampling Rate

The maximum sampling rate for a Lab Cradle using a single BT sensor is 100,000

samples per second. This sampling rate allows you to collect data for high-sample

sensors, such as microphones, blood pressure monitors and hand-grip heart rate

monitors.

If using more than one sensor at the same time, the 100,000 samples per second rate

is divided by the number of connected sensors. For example, when using:

• One sensor, data is collected at 100,000.

• Two sensors, data is collected at 50 kHz per sensor.

• Three sensors, data is collected at 33.3 kHz per sensor.

Some sensor’s maximum sample rates are less than the maximum sample rate of the

Lab Cradle. For example, with five sensors connected to the Lab Cradle, data may be

collected at 20 kHz per sensor; however, temperature sensors may only be capable of

collecting data at 1 kHz so it will only collect data at that rate.

Viewing Data Collection Status

The Lab Cradle has an LED light located on the top to indicate data collection status.

This light will be red, green or amber and use a variety of blink patterns.

Data collection

activity status

Red

• Red indicates that you need to wait until the system is ready.

•Slow blink: The Lab Cradle is updating experiment storage space. This is automatic

behaviour and does not impact active collections.

•Fast blink: Indicates one or more attached sensors are not warmed up. (You may

still collect data during the warm-up period but you risk the data being less

precise.)

Amber

• Amber indicates the system is ready but the collection has not yet started.

•One blink per second: The sensor is configured and set up for sampling.

•Slow blink: The Lab Cradle is connected to a computer or handheld running

TI-Nspire™ software but not set up for sampling.

•Fast blink: The Lab Cradle is ready for data collection when you press the trigger.

Green

• Green indicates the system is actively collecting data.

•Slow blink: Actively collecting data.

Note: There may be a slight variation in the duration of the blink depending on the

mode/rate of collection.

•Fast blink: Pre-storing data prior to a trigger.

Managing Power

When managing the power for the Lab Cradle, you must consider the power source

being used. The Lab Cradle can be powered by its rechargeable battery or a connected

power cord.

Batteries

The Lab Cradle runs on a rechargeable battery that supports one full day of high-use,

high-consumption sensor data collection before recharging. An example of high-use

data collection is an experiment requiring 150 total minutes of continuous data

collection with CO2(47mA) and O2 sensors at one sample every 15 seconds.

The battery recharges in less than 12 hours.

Viewing the Battery Status

There are two ways to view battery status: when attached to a handheld, or by looking

at the LED light. When the Lab Cradle is attached to a TI-Nspire™ handheld, you can

view the battery status for both. The first value is the handheld and the second value is

the Lab Cradle.

▶Press c 5 (Settings) 4(Status).

When you attach the Lab Cradle directly to a computer, you do not see a power

indicator. Use the LED light on the top of the Lab Cradle to determine battery status.

TOP

Battery

status

When the Lab Cradle is connected to a USB power source (either wall charger or

computer):

• Red - Slow blinking LED indicates the charge is low but charging.

• Amber - Slow blinking LED indicates the Lab Cradle is charging

• Green - Slow blinking LED indicates the Lab Cradle is fully charged.

When in the TI-Nspire™ Cradle Charging Bay:

• Red - Solid LED indicates the charge is low but is still charging.

• Amber - Solid LED indicates the Lab Cradle is charging.

• Green - Solid LED indicates the Lab Cradle is fully charged.

When running and not charging:

• Red - Blinking LED indicates the battery is below six percent.

• Amber - Blinking LED indicates the battery is below 30 percent.

• Green - Blinking LED indicates the battery is between 30 percent and 96 percent. Two

green blinks per second indicates the battery is over 96 percent.

Managing Battery Power

When the battery power reaches 30 percent, a yellow LED indicates the Lab Cradle

needs to be charged. The LED turns red when the battery power reaches five percent.

When managing battery power for the Lab Cradle, remember that some sensors need

to warm up before use. You can collect data while the sensor is warming up; however,

the data may not be as precise.

When you start a long-term or remote data collection, the system checks current

power sources to determine if the sources are adequate to support the sensors from

the beginning to the end of the experiment.

If the power is unable to support the experiment configuration, a warning indicates

that the power available is insufficient for the experiment. You either need to charge

the battery or plug the Lab Cradle into an external power source.

When using the wall charger, TI-Nspire™ Cradle Charging Bay or USB cable plugged

into a powered computer, the Lab Cradle can be fully charged from a dead state in less

than 12 hours when not being used.

The battery is capable of supporting one full day of high-use, high-consumption sensor

data collection or two full days of moderate to low consumption sensor data collection.

Charging the Lab Cradle

You can charge the Lab Cradle in a number of ways.

• Wall charger
