4.1 Description
4.1.1 Description
This chapter describes only the recommended check processes.
4.2 Device Status Check
4.2.1 Running Status
1. Check whether the ultrasonic device can be normally powered on and shut down (the startup
and closing time is within the allowed range) and whether the device runs properly without any
noise or error.
2. Check whether the fan runs properly without any noise or error immediately after the system
starts.
3. Check whether system basic information, such as product configuration and software version,
is correct on the system information page.
4. Check whether the display contract and brightness settings are correct.
5. Check whether the displayed date and time are correct.
6. Check whether the status indicator of the system is normal.
7. Check all log records with the user to confirm whether there is any abnormalities.
4.2.2 Operating Environment
Check the ambient temperature and humidity. The measurements related to safety features are
particularly sensitive to humidity. If the insulation feature of the system deteriorates due to the
increase of system service time or system malfunctions, the fluctuation range of measurement
results are likely to increase with the increase in humidity.
