When all calibrations are done, the all calibration parameter can be calculated at once:
Cal. Competed:
Calculate now?
YES NO
For each calibrations a single calibration plate with a cavity of 100µl is delivered together with the instrument.
Do not use the calibration plates for offset and reflectivity with algae to prevent wrong calibrations.
Offset calibration procedures
The offset is the detected fluorescence signal without any fluorescing matter. This is calibrated with a black
calibration plate delivered together with the instrument.
Black calibration plate
1. Put the BenthoTorch on the black calibration plate containing 100µl of destilled water. Do not reuse an
algae calibration plate to avoid contaminations.
2. Got to calibration -> offset
