8.4.2 Paper Feed
If the output mode is set to PLOT the paper feed speed can be programmed in
the range of 0.03 to 640 mm/h.
Paper Feed: Selection with key FUNCTION...
The input is carried out within function ´PF´, in mm/h, according to section 5.4.
From the paper feed velocity an internal print cycle can be automatically
calculated (see 7.2.3) where the measured values are scanned:
Print Cycle: PC [s] = 1280 / PV [mm/h]
If the conversion does not provide a print cycle in even numbered
seconds, the paper feed will correct itself during the input
accordingly.
If the print cycle is not sufficient for printing one line (1.8 s) and
measuring all channels, it will increase automatically.
The scaling of the time axis results from the print cycle. The time intervals of
the scale lines are listed in the header as SCALE DIVISION in minutes or
hours. The time hrs:min will be printed after every 6 lines and will also be
printed when the date changes.
8.4.3 Line Plot
The plotter can be started by using the key START/STOP if the output mode, plot
range and paper feed are properly set. Corresponding error messages will be
printed if this is not the case:
Start not possible:
Channel not existing
Error Plot range start/end
If the programming, including the limit values, has to be printed at the
beginning, the start must be performed within the function RANGE ´R´. In all
other functions only the data required for the evaluation of the diagram will be
printed, such as TIME, DATE, FEED and DIVISION. In addition, the RANGE,
DIMENSION and COMMENT, including the end values of the PLOT RANGE,
as well as a scale with 20 scale lines, will be printed for each channel (see print
examples). This scaling is repeated after 24 time-slot patterns.
After the start the arrow ´START´ will be illuminated in the display.
The first line plot is only provided after eight print cycles have
expired because eight rows of dots are printed in one line and each
measuring point scan is only presented in one row.
The output can be stopped by operating the key START/STOP once again. The
arrow ´START´ in the display will then turn off. In addition, the latest measured
values that have been acquired will be provided, along with the end time.
