4.2.2 Operating Instructions
Up to 12000 groups of NIBP data can be memorized. Using the Navigation Knob allows the user to scroll the list up and
down to view NIBP data. When rotating the knob anti-clockwise, the list scrolls upward. When rotating knob clockwise,
the list scrolls down. Please note that when the groups of data are less than 6, the Navigation Knob can not be used to
scroll up or down the listing.

Figure 4.3 HR Trend Graph
4.3.1 How to View the Graphic Trend
Figure 4.3 is the HR trend graph. There are 3 options on the right of the graph, as described below.
“HR” indicates the current trend graph is HR trend graph. If you want to enter other trend graphs, the procedures are:
move cursor to “HR” and rotate the “Navigation Knob” to choose the trend graph from “HR”, “S-T”, “Temperature”,
“NIBP”, “PR”, “RR” and “SpO
2
” trend graphs, next press the knob to confirm. Their screens are described in the following
figures.
After choosing “Cursor”, the trend graph will display a triangle and a vertical line, a moving ruler mark that can be moved
by rotating the knob. As shown in the figure, when you move the cursor to a specific point, the data area below the graph
will display the timestamp, and its corresponding heart rate, respiration rate, SpO
2
and temperature. When rotating
“Navigation Knob” key to move the cursor, the moving step is a variable value depending on the dialing speed. The rule
is that the initial step is 5sec, after moving it towards the same direction 1 time, the step becomes 30 sec, and with more
steps the step becomes 1min, 10min and 30min. Therefore, it is very easy to find the time point you are looking for.
The “5 sec” on the top shows the interval time. Move the focus to the trend time, press the knob and rotate it, and the
trend graph time will change to 30 sec, 1 min, 10 min, 30 min, which changes the horizontal axis to be 30 min, 3 hour, 6
hours, 60 hours, 180 hours. For example, the monitoring can record 360 times data continuously when setting to “5 sec”
within 30 minutes. Changing the interval time of 30 seconds, it can record 360 times data within 3 hours. Other changes
are similar to that situation.
The Trend graph shows parameter value of the current time. For example, in the “5 sec” trend graph, the monitoring
can record the current data with the interval of 5 seconds. Once the monitor is out of power, the data can be stored
automatically and you can scan the history record when turning on the monitor next time. This ensures the screen will
always display the current data continuously. Other trend graph follows the same rule.
Please note that the maximum value on the vertical axis of the HR is 150, not the value of HR upper limit (300). The graph
is scaled down for better view of the trend curve. When the HR value exceeds 150, the vertical axis’s maximum value will
automatically change to 300. That is to say, the vertical axis value 0-75-150 will change to 0-150-300 automatically if the
