and then release the button. Start the sensor in the
usual way.
•
If the sensor stops communicating with the computer
software or tablet application, try restarting the
software or application. If the problem remains, press
and
hold
the ON button for 10 seconds and then
release. Start the sensor in the usual way.
•
Turn Bluetooth off and then back on. Retry.
About the Battery
The sensor’s battery is partially charged at the factory. If
the battery status LED blinks red, use the micro USB cable
to connect the sensor to a USB port or a USB charger.
Battery Usage
Battery life is very important to making the sensor simple
and always ready to use, so all of the PASCO wireless
products are designed for long battery life. For example,
the sensor turns itself off after a few minutes of inactivity.
The battery life between charges for the sensor varies
depending on the sampling rate. The battery life ranges
between 11 hours for high sample rates to more than 70
hours for low sample rates.
In typical classroom/lab use, this would translate to a
battery life between charges ranging from one to four
weeks or more, because full-day continuous sampling
would be unusual. Even in the most extreme case with a
high sample rate, the sensor battery would support a full
day of use before needing to recharge.
Maximizing Battery Life
One factor that affects battery life is the storage
temperature and the number of charge cycles. Therefore,
avoid storing the sensor in very cold or very hot
environments.
Suggested Experiments

Measure Magnets and Electromagnets
Study the field strength of various permanent magnets and
electromagnets.
Field Strength of a Solenoid or of Helmholtz Coils
Use the sensor with a PASCO Rotary Motion Sensor to
examine the field strength inside a solenoid or between
Helmholtz Coils.
