Campbell Scientific PWS100 Present Weather Sensor - Manual (Page 77)

Section 7. Operation
To set the adjustable visibility limit parameters, type:
SETPARAM vislim1 vislim2 vislim3 snowwater mixthreshold ↵
The system will respond by displaying the new settings as described above
with SETPARAM
↵ command. Please see Section 7.4.5 for a description of the
thresholds.
TABLE 7-4. Weather parameters.
Parameter Function
VISLIM1 Set a visibility alarm below which a particular alarm
will be given.
VISLIM2 Set a visibility alarm below which a particular alarm
will be given.
VISLIM3 Set a visibility alarm below which a particular alarm
will be given.
SNOWWATER Set a snow water content parameter from which water
equivalent accumulations will be derived.
MIXTHRESHOLD Set a threshold for the reporting of mixed precipitation
as a proportion of the most populated precipitation type.
7.6.2 Receiving Data from Remote Sensors
Instead of using data from sensors directly connected to the PWS100, it can be
sent data from remote sources (e.g., a different temperature and humidity
sensor connected to the controlling system/datalogger). To do this, the TRH
sensor type needs to be changed to the remote sensor option and the data sent
to the PWS100 by the controlling system at regular intervals (e.g., every
minute). The RSENSOR command is used as follows:
RSENSOR Pws_Id Temperature Humidity ↵
Temperature should be in degrees Celsius and humidity as a percent (0-100).
The PWS100 will use the last values sent to it for its particle discrimination
decisions.
7.7 System Configuration Commands
7.7.1 Setting System Parameters
The system configuration parameters can be viewed using the CONFIG
command and those capable of being set by the user are set using the
SETCONFIG command. To view the system configuration parameters, type:
CONFIG ↵
