User Interface The user interface of the M508 Single Beam Spectrophotometer includes Basic Mode (Abs, %T, Conc), Quantitative (concentration calibration curves), Wavelength Scanning, Kinetics (including timedrive), DNA/Protein, Multi-wavelength, and Performance Validation. In Basic Mode, the result is continuously displayed (no need to “press to read”) PC Control The M508 has an RS232C output for the transfer of results to a PC and for PC control of the M508. Comprehensive Camspec Application Software is available, together with small PC programs, dedicated to specialist tasks. A selection of...
