Data Collection

  • Collect data from multiple sensors simultaneously, either with a multiple-channel interface such as LabQuest Stream or by using multiple Go Direct sensors. Use Data Sharing to retrieve data from just about every Vernier sensor.
  • Select time-based or event-based data collection, including events with entry.
  • Adjust data-collection rate and duration as needed.
  • Trigger time-based data collection on sensor values.
  • Calibrate sensors, although most of the time this is not needed.
  • Enter data manually or using the clipboard.
  • Change display units on many sensors.

Data Analysis

  • Display one, two, or three graphs as needed.
  • Set the graph scale.
  • Select what is graphed on each axis, and select line- or point-style graphs.
  • Calculate descriptive statistics on all or some of your data.
  • Fit lines and curves to some or all of your data.
  • Define calculated columns based on sensor columns. Use this to linearize a graph, for example.
  • View data in a table.
  • Highlight and read values from a graph.
  • Interpolate and extrapolate using graphed data.

Data Sharing

  • Receive data shared from LabQuest 2 or a computer running Logger Pro 3 to support 1:1 lab groups.

Data Storage
