CHAPTER 6 DESCRIPTION OF THE MEMORY-FUNCTION
6 Description of the Memory-Function
All data recorded via START are automatically stored in RAM-
memory with a capacity of 4000 data sets. They can be recalled on
display via the MEM-key. Then, for example, the following
information is shown:
MEM 382: 12:27 27/MAY/95
A: 322Y 21.1E 157L
In the top line it can be seen that the data set Nr. 382 of the
current MEMORY was recorded at 12:27 o'clock on May 27th 1995.
The bottom line shows that a sample of type A was used (see
MODE-menu point 51), which displayed a YIELD-value (Y) of
0.322 and an apparent ETR-value (E) of 21.1 at an incident light
intensity (L) of 157 µmol quanta m

of the photosynthetically
active radiation (PAR).
More information relating to this particular data set can be
displayed in the top line by SET-operation:
MEM 382:390F 576M 19.9C
A: 322Y 21.1E 157L
After the first SET, the top line shows that the fluorescence yield
(F) measured briefly before the saturating light pulse was 390, that
the maximal fluorescence (M) amounted to 576 and that temperature
was 19.9 °C.
MEM 382:645P 759N 1.557Q
A: 322Y 21.1E 157L
After the second SET, the top line shows the quenching
coefficients qP=0.654, qN=0.759 and NPQ=1.557, which will be
meaningful only if for this particular sample a Fo-Fm determination
