Why is the absorbance reading on my device (spectrometer/colorimeter) unstable or nonlinear at values above 1.0? How do I check the lamp output of my spectrometer? What is the difference between the V-SPEC and the GDX-SVISPL? Why does one cost so much more than the other? What is the difference between the Go Direct Visible Spectrophotometer and the Go Direct SpectroVis Plus? Why does one cost so much more than the other? My Go Direct SpectroVis Plus Spectrophotometer intermittently drops the connection while using Bluetooth. My Go Direct SpectroVis Plus is not identified or is not responding in software.ĭoes my Go Direct SpectroVis Plus Spectrophotometer firmware need to be updated? My LabQuest 2 or 3 locks up or is not identified when connected to a SpectroVis Plus. Why does my LabQuest battery drain so quickly when connected via USB to a Go Direct sensor/spectrometer? How is the Go Direct SpectroVis Plus Spectrophotometer different than the SpectroVis Plus? It won't calibrate or is giving very noisy data. The AC power adapter is only needed to charge the battery and is not required for operation. In general, we recommend removing the GDX-SVISPL battery if you are not using the device wirelessly. Removing both of these will likely solve most issues. Secondary Test: If you are collecting data via USB, you do not need the battery installed or the AC power cable connected. Primary Test: Are you using Logger Pro v3.14, LabQuest App v2.7.2, or Spectral Analysis v4.4 (or newer)?
