3.5 Rain Gauge
The rain gauge can not be used for conditional sampling. The data logger
automatically collects rainfall data in a counter that is reset by clearing the
accumulator (Setup – Logger Setup menu.) The rainfall counter value is stored at the
programmable averaging periods. By looking at when the rainfall data increases, the
time that the rainfall occurred can be worked out.
The MicroVol data logger increments each time the rain-gauge bucket tips. The data
value increases until the data logger is reset using the Setup - Logger setup - Clear
Accumulator menu.
Note: Clearing the accumulator will clear all
data in the MicroVol-1100 internal data logger.
The rainfall units are “tips”, which refers to the number of times the rain gauge bucket
fills and empties. The units can not be changed. Multiply the data by the calibration
factor to convert to millimetres or inches of rainfall.
