LabChart Training Course Note

Two modules of LabChart training were attended:
Level I: The Basics of Data Acquisition
Level II: Improve Your Data Analysis

In Level I, we were guided to set up PowerLab and LabChart unit. Generally, an overview of the PowerLab hardware and how it connects to pc/laptop were demonstrated, and then individual practiced once to connect and select the right channels.
∎ Selecting the number of recording input channels that are required for certain experiment
∎ Configuring the display features of your file including time format, colour and style of the signal waveform
∎ Deciding to record in Chart View (continuous recording) or Scope View (traditional oscilloscope short page format)
Sampling Rate
∎ Available sampling rates for PowerLab
∎ The theory of required sampling rate relative to waveform type and frequency
∎ Using Spectrum to find maximum signal frequency
∎ The effects of undersampling/oversampling and the concept of aliasing
Range
∎ Deciding on the correct range for your signal type
∎ Signal resolution and signal-noise ratio
∎ The effects of choosing the wrong range
∎ The difference between Range and Scaling
Amplification & Filtering
∎ When does a signal need amplifying?
∎ Input amplifier settings
∎ When to filter and different hardware filters including mains, notch, high pass and low pass
∎ Hardware filters versus software filters
Visual Features in LabChart
∎ Scaling options
∎ Compression features
∎ Split Screen option
∎ Digital Volt Meters
Saving Options
∎ Different LabChart File types including data files and settings files
Manage Files
∎ Using the LabChart Welcome Centre to store files
∎ Accessing recently used
