The paper has to stop exactly at the perforation. If this is not the case, con-
trol the paper mark comparison.
5.2.8 Printer quality test page 36
1.
Check the blackness for regularity and good readability on the complete
print width.
2.
Check on the 25 mm/s printout if the space between 2 R peaks according
to the paper grids. The space should be 25 mm and may not show a dif-
ference of more than ± 0.5 mm.
5.2.9 Printing Speed page 36
1.
Check on the 25 mm/s printout if the space between 2 R peaks according
to the paper grids. The space should be 25 mm and may not show a dif-
ference of more than ± 0.5 mm.
5.2.10 Parallelism test page 37
1.
All calibration impulses should be lined up vertically and exactly below
one another.
2.
The maximum deviation may not be more than ± 0.5 square. If the values
are outside this tolerance, the mechanical adjustment of the print head
has to be corrected.
5.2.11 ECG amplifier page 37
1.
Check the amplitude height of the calibration impulse according to the pa-
per grid. It should be 20 mm ±0.5 square.
