Texts can be printed in two modes:
- by interrupting the measurement trace (Outplot)
- overwrite the measurement trace (Inplot)
The text is printed as fast as possible. During the text printing there is no re-
cording of measurements or event traces. The chart paper speed is optimised
for the text printing. It is not the same as the programmed chart speed.
Typically, a time of 10 — 40sec is needed to print a line of text.
Advantages:
- rapid text printing
- other messages are blocked for the shortest possible time
- an optimised chart speed ensures that the text is always perfectly legible
- text printing can also be carried out when the chart speed is programmed
to 0mm/h.
Disadvantages:
- measurements and event traces are not recorded during the text printing
- the chart speed is altered during the text printing. The time correlation is
lost.
The text is printed with the current chart speed. Measurements and event trac-
es are printed at the same time. Text printing is not performed if the chart
speed is 0mm/h. At this chart speed, texts which would be printed in the
"Overwrite measurement trace" mode are not recognised in the priority evalu-
ation.
The time taken to print a line of text will vary, depending on the programmed
chart speed.

5mm/h
20mm/h
120mm/h
Advantages:
- the time correlation is also preserved during text printing
- the recording of measurements and events is not interrupted at any time.
