5-4 Checking Performance and Functions
5.3.2.3 Checking Peripherals
Footswitch: confirm the normal connection
between footswitch and USB port. Check
the configuration status of footswitch under
[Key Config] and corresponding
implementation. (E.g. right key-image
freeze; middle key-
key-white/black print).
Trigger the freeze key of the footswitch (right key).
Image freeze menu and freeze menu appear. The
image is unfrozen if the key is triggered again.
Trigger the print key of the footswitch (middle key).
Start color print.
Trigger the print key of the footswitch (left key). Start
black/white print.
Video printer: confirm the connection
between video printer and ultrasound
device works well and check the
implementation of each function.
Press the Print key which is setup well already to start
the print. The image has no defect or degradation.
Switch video output terminal. Then repeat the
previous steps.
Graph/text printer: confirm the connection
between graph/text printer and ultrasound
device works well and check the
implementation of each function.
Press the Print key which is setup well already to start
the print. The image has no defect or degradation.
Barcode reader: scan any piece of barcode
when the system is under running.
The barcode information displays on the image
interface. The information is correct compared with
the data information of barcode.
5.3.2.4 Checking ECG Module
Procedure Checking criteria
Perform the following tests after the
system is configured with ECG
module:
Connects ECG lead.
Move the cursor to image menu.
Click [Physio] to enter its interface.
ECG activation, ECG waveform and heart icon appear on
the right corner of the interface.
The parameters for [Scan speed], [ECG gain] and [ECG
position] can be adjusted in real-time.
Review ECG signals.
5.3.2.5 Checking I/O Interface
Procedure Checking criteria
Checking I/O interface
Verify video/audio interface, USB port, etc.
VGA interface
Connect external VGA/LCD monitor (the resolution
should be one of them: 1920*1080,1024*768,
1280*1024,1280*720).
Other USB ports
The information on VGA/LCD monitor is
same with that on the screen of main
unit. The characters and images are
complete; the images are stable; no
color cast; no shaking and no blinking.
Network connection and communication
work well.
USB storage and read work well.
