WRL
Weather Report Logger
The WRL senses wind, temperature, humidity, barometric pressure, rainfall and time, then
outputs this data via a RS-232 interface to other devices. The WRL can be programmed
to output current weather, along with minimum and maximum conditions for the day. The
WRL keeps track of two different minimum and maximum values and up to 8000 lines of
data (depending on memory size) in its non-volatile memory clock. The WRL-10 has 2K of
memory and will retain approximately 30 l

There is lightning protection (transient voltage suppressers) built into the junction box. It is very important that the mast is grounded or else the transient voltage suppressers will not protect your instrument. The junction box picks up earth ground through the hose clamps mounting the box. We suggest that you install a copper-grounding rod (available at Radio Shack) and run the heavy gauge wire directly behind the hose clamps of the junction box. This arrangement will ground your mast and

collector unencumbered by surrounding obstacles. Use a bubble level to make sure that the collector is perfectly level with the ground. Failure to level the collector will cause inaccurate rainfall readings. The rain collector has one blue cable, which must be connected to the console via the junction box. Mount the junction box under the rain collector using the hose clamps that are installed on the box (see figure 1)and remove the front cover of the junction box. Next insert the connectors

Calibration The Weather Report comes pre-calibrated from the factory, but it is possible to recalibrate most of the primary functions of the instrument using TWICAL program. Barometric Pressure Normally, barometric pressure is the only item that needs to be recalibrated (adjusting for altitude). The proper local barometric pressure can be obtained from the local news. Set the barometric pressure reading you obtained from the local media by using the calibration mode function. Temperature If for
