4.8.2 <PLOT> key
PLOT
1
The <PLOT> key is used to start the graphics plot on an external
printer connected to the RS232 interface. The output is started directly
at a keystroke, no inquiries appear.
Preparations
• Under "SETUP" the general graphics parameters (frame, grid, print
width) must be set to the desired values (see section 4.4.1).
• Under <CONFIG> printer type and RS232 settings for the output on
an external printer must be correctly selected (see section 4.4.2).
• Under <PARAM> the parameters effective for the graphics plot
must be set (see section 4.5.1).
Elements of the measured value output
Depending on the parameter settings selected under "SETUP",
<CONFIG> and <PARAM>, the graphics plot can comprise the fol-
lowing elements:
• Print header
The print header comprises title line (device name, serial number,
program number), identifications 1 and 2 (if used) as well as the
date and time if required (see section 4.4.2) and is outputted once,
always or never before a graphics plot, depending on the setting of
the parameter " >CONFIG/printer/print header " .
• Grid
With " SETUP/grid = on " grid lines are drawn in.
• Frame
With " SETUP/frame = on " a frame is drawn in.
• Labeling of the y axis
Conductivity in µ S/cm, mS/cm or S/cm
• Labeling of the x axis
Absolute time " HH:MM:SS " or relative time " XXXmXXs "
• Conductivity measurement value
