CHAPTER 5 

OPERATION OF THE JUNIOR-PAM 

Printing report data 

The <Options> menu includes the command <Print Report> and 
two extra print options: 

<Page Setup for Printing> Adjust page design settings. 

<Preview Printing> Show the appearance of the printout. 

Provided that data have been selected, two additional print com-
mands are available. 

<Preview Print Selection> Visualize the print design of selected data. 

<Print Selected Data> Print only selected data. 

Export report data  

Similar as described for printing, the parameters exported can be 
selected by the checkboxes on the sidebar. In analogy to the print 
commands: 

<Export All> exports all data in CSV (comma separated values) format 
which can be imported into most spread sheet programs and 

<Export Selected Lines> exports only the selected data. 

 

Table 5.2: Report Data - Abbreviations 

D 

Identification of device: number, type and user annotation (see 5.6.1) 

F 

SAT Normal operation and saturating flash 

FO 

Fo, Fm determination 

REG1  Parameters of regression 1 (see 6.4) 
REG1  Parameters of regression 2 (see 6.4) 
SCHS  Start of new record/Chart start 
SICE  End of induction curve 
SICS  Start of induction curve 
SLCE  End of rapid light curve 
SLCS  Start of rapid light curve
