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. Alternating Amber and Green • The blinking pattern indicates the system is in trigger mode but has not yet reached the trigger event. 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. TI-Nspire™ Lab Cradle 95

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.
