Weather Report Logger™
Digital Weather Station
WRL-25, WRL-32 & WRL-128
Thank you for purchasing a Weather Report. Your package should contain a WRL console, wind
sensor, temperature/humidity sensor, rain collector serial cable and a diskette that contains the
TWI_LOG software. The WRL is unique because it can be programmed and queried by both the
buttons on the display and by PC via the RS-232 serial port. Also data can be saved internally or by
an external device via its RS-232 port. By accessing the logging mode (press
select
and
time
hold)
the user can access previously logged data, up to 8000 lines in the WRL-128 Version, 2000 lines of
data in the WRL-32 or 30 lines of data in the WRL-25.
Normal Operation
When in normal operation (no buttons depressed). the instrument displays current wind direction
and speed, cycles current time and date, cycles current indoor, outdoor and if selected, aux
temperatures (if both the indoor and outdoor indicator lights are extinguished, Aux. temperature is
displayed) cycles current barometric pressure, current relative humidity, and cycles daily, monthly
and term cumulative rainfall. By utilizing the hold buttons associated with each display, the user may
select the most important readings to the user. When wind speed in excess of 99 miles per hour are
experienced a small light will turn on between the digits of the wind speed display.
Trend indicators
(arrows) are located to the right of the temperature, relative humidity, and
barometric pressure displays. If, for example, the current relative humidity was increasing the up
trend arrow would be lit. If there was no change, no arrow would be lit.
INSTALLATION
We strongly suggest that all the weather station cables and sensors be connected to the
weather station and tested prior to installation so that you may become familiar with the
operation of the instrument.
The WRL uses three sensors to gather weather data. The wind direction and speed sensor, the
temperature and humidity
pagoda
and the rain collector (
see figure 1
). All are designed to mount to
a television type mast (
not provided
). The cables from the sensors go into a
junction box
