Go!Temp and Go!Link both have this issue.<\/p>\n<p>If you try to collect at a slower rate it will collect a sample every 30 minutes for the desired number of points, and mislabel the times as if they&#8217;d been collected at the desired data rate. For instance, if you try to collect one sample per hour for 24 hours, you will end up with a table\/graph with 25 points, with a time column that indicates 0, 1,&#8230;24 hours; but the collection will be finished in only 12 hours, and the point labeled &#8220;1 hour&#8221; will actually be collected at time 0.5 hours. As this can be confusing, the easy solution is to just collect at two samples\/hr (or faster).<\/p>\n<p>Workarounds:<br \/>\n-Change the data collection rate to two or more samples per hour.<br \/>\n-Use a sensor plugged into the analog (CH1-3) ports.<\/p>","protected":false},"excerpt":{"rendered":"<p>LabQuest can&#8217;t collect from Go!
