Release Notes

LabChart Known Issues

Windows

  • LabChart 8.1 or later do not support Windows Classic theme.
  • In the Preset Comment "Event Configuration" dialog, if "Comment only on first stimulus" is checked, the comment is disabled for the entire record after the first pulse.

Mac

  • If you are on OS X v10.11 (El Capitan) and have already upgraded to LabChart 8.1.2 - Please upgrade to 8.1.3 here on our website rather than in feature manager. You can then proceed as normal for all future upgrades.
  • There are some features that were present in LabChart 7 that are not currently included in LabChart v8.1. Click here for more information.
  • The ADInstruments Blood Flow Meter is occasionally initialized with only one channel enabled. The user can manually enable the second channel.
  • For machines that have high-resolution Retina displays, users may encounter responsiveness and stability issues when using the Scope View.

LabChart 8.1.17 (Mac)

Mac changes

  • Fixed an issue where a calculated channel unexpectedly stops producing data while sampling.
  • Fixed a pod setup issue such that the Grip Force transducer now produces correct data values during sampling.

New Known Issues

There are no new known issues in this release.

LabChart 8.1.16 (Mac)

Mac changes

  • Fixed issue where using the FE2XX Series Bio-amp (Octal, Quad, Dual and Neuro amps) input Low pass filters with cutoff frequencies of 1 kHz or lower could introduce inter-channel delays of up to ~1.5 ms.
  • Fixed issue where the FE2XX Series Bio-amp bandwidth was lower than expected at sampling rates below 100 kS/s. This also affected sampling with slave devices when sampling from multiple devices into the same document, e.g. when sampling with two PowerLabs the slave device would have a lower bandwidth than the master device.
  • Fixed issue with the delay compensation for FE2XX Bio-amp inputs. The delay between a signal recorded via the Bio-amp input relative to that recorded by a PowerLab input is now less than +/- 10 µs for sample rates above 100 S/s, and less than +/- 1 sample period for all sampling rates, so long as the PowerLab input and Bio-amp input have the same input low pass filter settings (including the case where the input low pass filters are both off).
  • New PowerLab Red enabler improves the self-calibration of 15 and 26 series PowerLabs (i.e. offset calibration on startup).
  • Fixed issue where making a selection in the Chart View could cause a bad access in the Zoom View.
  • Fixed an issue that prevented opening some files saved with LabChart 7 or earlier.
  • Fixed an issue where comment text is incorrect within certain files saved with LabChart 7 or earlier.
  • Fixed an issue where searching in the Help would return no results.
