The OS1p has four different test protocols. Each mode providing the necessary setup and
data logging for each type of test.
Press “Test Menu” using the touch screen and the measuring protocols will appear. Press
the button for the measuring protocol that is desired.
Fv/Fm Protocol ⎯ Dark adapted Fv/Fm test for maximum quantum yield.
1. Y(II) – Quantum Photochemical Yield Protocol ⎯ Light adapted test of (PSII) for
effective quantum photochemical yield - Y(II) or )F/Fm’
2. Y(NO) NPQ – This represents the Luke Hendrickson simplified lake model
quenching equations along with NPQ resurrected from the puddle model by
Klughammer for the lake model. Parameters include Y(NPQ), Y(NO), Y(II), and
NPQ. When used with a PAR Clip, PAR, leaf temperature, and ETR are also
reported.
3. RLC – This is the protocol for rapid light curves. It will be available in 2011.
Parameters include ETRmax, Ik, and " are provided.
* Other quenching protocols may be delivered in place of the Luke Hendrickson model
upon customer request. Other protocols may also be added for an additional price.
Optional quenching protocols include: Dave Kramer’s lake model parameters, puddle
model parameters, and a quenching relaxation protocol that may be added to the
Hendrickson or puddle model protocols.
