What are the instructions given for using a Portable People Meter?

The correct instruction regarding the use of a Portable People Meter is to take the meter with you and recharge it at bedtime. This is essential for ensuring that the device is always operational and ready to capture data accurately throughout the day. The Portable People Meter is a tool used for measuring audience engagement and listening habits, and it needs to be regularly powered to function effectively.

By recharging it during the night, the user ensures that the device is fully operational for the following day. Additionally, since the functionality of the meter relies on its ability to remain on and engaged with the user’s activities, letting it recharge at a time when it is not needed—such as during sleep—maximizes its usage time.

Other options may emphasize aspects of carrying or wearing the device, but they do not address the crucial need for ensuring that it is consistently charged and ready for use. Proper usage and maintenance are vital for collecting accurate data, which is the primary goal of utilizing such a measuring device.
