Printing Monitor Trend Data
When a real-time printout or display is being transmitted to a
printer or PC, a new line of data is displayed every 2 seconds.
Column headings are displayed or printed after every 25 lines, or
if one of the values in the column heading changes. Readings are
displayed at 4-second intervals if the SpO response mode is set
2
to normal and at 2-second intervals when the SpO2 response
mode is set to fast.
Data cannot be obtained if the N-600x is operating on battery
power.
Note: If the data output stops transmitting, turn the power off
and back on again or, if the monitor is connected to a PC, send
an XON (Ctrl-q) command to reset the monitor.
