The system may be operated in several different modes: serial connection to a Windows® PC enables real-time instrument control and data presentation. Captured data is simultaneously presented as a real-time chart recorder emulation and parameters-only format for easy identification of key experimental events. This PC mode of operation is suitable for development of complex protocols which may be programmed into the instrument using the simple drag-and-drop editor to generate user-defined scripts. These scripts automate the execution of experiments in the field, allowing complex protocols involving many control events to be operated with the same ease as single control event measurement such as Fv/Fm. Once programmed, the FMS 2+ can be used as a stand-alone chlorophyll fluorimeter in either laboratory or field situations, running from internal batteries with all measurement data and calculated parameters saved to integral protected memory. The unit can store up to six experimental protocols, any one of which may be accessed and executed using the built-in menu system. When data collection is complete the results can be downloaded to the Windows® software for full analysis.
All of the light sources required for modulated measurement of common chlorophyll fluorescence parameters are self-contained within the instrument.
-594 nm amber modulating beam with 4-step frequency control. (Optional 470 nm blue LED)
-Dual-purpose ultra-bright LED light source providing actinic light (0 µmol m-2 s-1 – >4,000 µmol m-2 s-1 in 50 steps) and saturating pulse (0 µmol m-2 s-1 – >13,000 µmol m-2 s-1 at the sample surface in 100 steps)
-735 nm far-red LED source for preferential PSI excitation allowing accurate determination of the Fo’ parameter
