c. If the malfunctioning sensor is measured by the logger:
- Open the sensor calibration view in the AWS Client
software; see section Determining Sensor Status on page
213
- Check the sensor status and compare the value against the
sensor status list Appendix D, Sensor Status Values, on
page 293.
d. If the malfunctioning sensor is a so-called intelligent sensor,
for example, WMT703, use its own diagnostic features.
- Connect the maintenance cable and start the AWS Client
software.
- Service interface for the intelligent sensors can be
accessed through the QML logger as explained in section
Opening Service Connection through QML Logger on
page 206.
10. Communication is not working properly.
- Whenever possible, use an external device to verify that the
communication infrastructure is working properly. For example,
use a cellular phone to verify that the signal strength in the site
is sufficient or that the system SIM card has access to the
network.
- See also section Troubleshooting TCP/IP-Based Telemetry on
page 215.
11. Data is not stored to a memory card.
- Check the status of the memory card. It is indicated by a LED.
Table 45 on page 162 describes the different blinking sequences
and the card conditions they indicate.
Is the QML logger still not functioning? Replace the logger and return
the damaged one to Vaisala for repair. For return instructions, refer to
section Product Returns on page 235.
