BDA 387/2 A Product Description A1 Concise Operating Instructions To turn spectro-color® on and off, press the flush button on the top of the instrument. The warning „Instrument not calibrated for 24 hours!“ appears after 24 hours without calibration at the latest. Press the centre black key yes to call the calibration function directly. If you do not wish to calibrate, because e.g. the calibration standard is not available, you can also measure without previous calibration.
BDA 387/2 A2 Introduction spectro-color® is a colorimeter operating on the spectral method described in DIN 5033 using the d/8° circular viewing geometry, i.e. the sample is illuminated with polychromatic light with the optical unit observing the reflected light from a 8° position towards the sample surface. spectro-color® is a genuine grating colorimeter measuring the visible spectral range (400nm to 700nm) at intervals of 10nm. A special reference beam system ensures highly reproducible measurings.

BDA 387/2 C Applications C1 Calibration It is recommended to calibrate spectro-color® at least once a day. spectro-color® should also be calibrated before every set-off measurement or after extended breaks (several days). After 24 hours without calibration, a warning is issued on the display Go for yes to skip directly to the calibration routine. If you don’t want to calibrate, because e.g. your calibration standard is not on hand, you can continue measuring without recalibration.
