Resetting the datalog
RESET-DATA: This command will erase the datalog and will insert
one current Sample record.
Displaying current Hi/Lo
HIGH: This command will display the current high record. The High
record starts with the letter H followed by the date and time the
record was requested followed by the high values and the time for
wind speed, relative humidity, pressure, temperatures, leaf wetness
and two undefined sensors (X1 and X2). The high value of wind
speed is the wind gust.
Example:
H,02/11/98,14:00,013,13:25WS,081,13:40RH,29.86,13:27P1,+053.23,14:00T1,+072.27,13:
52T2,+069.59,13:31T3,+065.88, 14:00T4,01.70,13:57LW,0.00,14:00X1,0.00,14:00X2,8351
LOW: This command will display the current low record. The Low
record starts with the letter L followed by the date and time the
record was requested followed by the low values and the time for
wind speed, relative humidity, pressure, temperatures, leaf wetness
and two undefined sensors (X1 and X2). The low value of wind
speed is the high 4 second sustained wind average.
Setting temperature offsets
Temperature offsets are used to calibrate the temperature probes.
n TCAL#: This command is used to enter an offset for a temperature
probe. Where n is the offset in 1/100 of a degree F and # is the
temperature probe number.
Example: 231 TCAL2 adds 2.31 degree F to the temperature
reading from temperature probe two and -231 TCAL2 subtracts 2.31
degrees F from the reading.
Please refer to the Temperature Calibration section for more
information.
Setting barometric pressure altitude
and offset
n ALT: This command sets the altitude of the weather station, where
n is the altitude in feet.
Example: 225 ALT sets the altitude to 225 feet above see level.
n BAR-OFFSET: This command is used to enter an offset to the
barometric pressure reading, where n is the offset in 1/100 of In.Hg.
