4.8.2 Print quality and printer alignment check (page 25)
1. No fading
2. Alignment OK
3. No faulty pixels
4. Blackness, regularity and good readability on the complete print width
1. Paper stops at the perforation (paper mark)
1. On the 25 mm/s printout the space between 2 R peaks is 25 mm ± 0.5 mm.
1. Calibration waveforms line up vertically and the maximum deviation is not
more than + 0.5mm.
1. RS-232 Ports change colour when the test plug inserted.
2. DC IN and DC OUT ports change colour when the test cable assembly is
connected between the two connectors.
3. ERGO square changes colour when the test plug inserted.
4. ERGO square changes colour when the switch set.

– all lead designations highlighted
– the mV reading for all leads is -350 to -550 mV
2. Connect ECG simulator:
– all leads stop blinking
– the mV reading for all leads is -15 ...+15 mV
