TROUBLESHOOTING

Primary Test: Are you using LabQuest App v2.8.8 or v3.0.5, or Spectral Analysis v4.11, Logger Pro 3.16.1 or newer?

  1. Connect the AC power supply to the spectrophotometer. Turn the power switch to the ON position. Wait for the lamp indicator LED to remain green.
  2. If connecting via USB: Connect the spectrophotometer directly to the USB port. If connecting via bluetooth (Go Direct version only): Connect the spectrometer to the USB power adapter or to a powered USB hub. The bluetooth LED will blink. Note: Do NOT plug the USB into a computer USB port to run with Bluetooth.
  3. Start the appropriate data-collection software. Options include: Logger Pro 3, LabQuest App, and Spectral Analysis. The latest version of software is available as a free download here: https://www.vernier.com/downloads/
  4. Set the spectrometer to collect data in absorbance vs wavelength mode, if not already done.
  5. Calibrate the spectrometer with the appropriate solvent.
  6. Collect a spectrum with a known sample where the absorbance falls between 0.1 and 1.0 absorbance units.

SPECIFICATIONS

CALIBRATION
You must calibrate the spectrometer every time you use Absorbance or %T mode. Calibration is not required for intensity.
