When I plug in a Power Amplifier, it is not recognised.

Our Power Amplifier will not be automatically recognised by either LabQuest app or Logger Pro. To use it and control the output you need to follow the instructions below.

If you are using the LabQuest alone (no computer), you want to use the Power Amplifier application. Click on the little house icon at the bottom of the LabQuest screen and then select Power Amplifier.This will give you controls to set the output signal's frequency, waveform, and amplitude. You can run the LabQuest app at the same time, if you like.

If you want to use the Power Amplifier when connected to a LabPro or LabQuest with a computer, use Logger Pro 3.8 or newer. Select Set Up Sensors, or click on the LabQuest icon on the left of the toolbar. Then click on the Power Amplifier button. This gives you controls to set the output (frequency, waveform, amplitude).
