CHAPTER 6

TROUBLESHOOTING

This section consists of some common MAWS problems, their
probable causes, and remedies.

Data Validation

For most of the sensor inputs, there are data validation parameters to
check the following measurement's quality parameters:

- Maximum value: the maximum climatological value for the sensor

measurement.

- Minimum value: the minimum climatological value for the sensor

measurement.

- Step change: the maximum step change for the sensor value

between two consecutive measurements.

All of these parameters can be set by the user using the MAWS Lizard
setup software. For more information, refer to the User's Guide listed
in Table 2 on page 15.

If the sensor value is outside of the maximum or minimum values, or
it has altered more than the maximum step change allowed, then data
will be flagged as INVALID. Invalid data is typically displayed as /////
(this is a user settable parameter). If a sensor displays invalid data, this
is an indication that the sensor is faulty or out of calibration, or there
is a problem in powering or measuring the sensor.
