Sample detection in Agera is used to make sure that sample is placed at the Agera port before taking a measurement. It works for most types of samples. When no sample is detected, "Sample Not Present" error is prompted. However, sample detection can not recognize some dark samples with high gloss, like dark denim.
If a sample is placed while "Sample Not Present" is prompted, please consider to disable sample detection for these types of samples' measurement.
We added the feature to enable/disable sample detection in Agera Essentials Rev 1.06.0099 and above. To enable/disable Sample Detection, please go to Workspace menu/Diagnostics/Advanced diagnostics.
