the valve is opened permanently, the patient monitor prompts “APNEA ALARM”.
Unplug the water trap. The patient monitor prompts “CO
2
water trap OFF”. Plug the
water trap again. The prompting message disappears.
When the measured value exceeds the high limit of CO ③
2
, the patient monitor
prompts “CO
2
too high” on the main screen. When the measured value is lower
than the low limit, the patient monitor prompts “CO
2
too low”.
5.1.10 Recorder
1. Print the ECG waveform. The recorder should print it normally and clearly. Set
the recorder to the fault of lack of paper and abnormal clip. There should be relevant
prompting messages on the main screen. When the fault is cleared, the patient
monitor should become normal.
2. Print the alarm messages of all parameters. Set the alarm print switch to ON for
all parameters, and set different alarm limits. Then the recorder should print the
alarm message in case of an alarm
.
5.1.12 Power Supply
When the patient monitor is supplied with the external AC power, the CHARGE
indicator becomes ON. When it is disconnected from the external AC power, the
CHARGE indicator becomes OFF. After the patient monitor is started without
assembling the batteries, “x” is displayed in the battery indication frame on the main
screen. After the batteries are assembled, the battery electricity is displayed in the
battery indication frame on the main screen. The patient monitor can work normally
with or without batteries. It, however, should give an alarm when the batteries are
exhausted.
5.1.13 Clock
Verify the correctness of the clock in the system test, and then set the clock to the
current time.
5.1.14 System Test
Load all parameters, and conduct operations respectively on the loaded parameters.
During the synchronization, no exceptions (for example, mutual interference) occur.
Set all parameter setups in menus to the default values which are those at the time of
software loading, and conduct operations on the menus, for example, managing the
patient information, recalling data, and so on. All the operations should be done
normally, and the corresponding functions should be correct and meet the product
requirements.
