The total shake down period should be approximately 50 s. If it takes longer than 75 s to
equilibrate, the SC-1 may have a problem. Refer to Section4.3.
7. Once the measurement chamber has dried and equilibrated, the Measurement tab will
display a prompt to insert the leaf (Figure10).

8. Choose to measure adaxial (the top of the leaf) or abaxial (the bottom of the leaf)
conductance, depending on plant type and desired data.
9. Orient the leaf appropriately for the measurement. The dessicant chamber must always
be oriented down (Figure11).
