5.10.3 Rain Logger Setup

The Rain Logger is programmed using the Logger Settings Window of the Levelogger Software. The appearance of the Logger Settings Window when in communication with a Rain Logger is shown in Fig 5-15.

Setting up and Starting a Rain Logger is a quick and simple process. Identify the logging session and location in the Project ID and Location fields. The Sample Mode for the Rain Logger is Linear. Input the Sample Rate from 5 to 90 minutes. Use a sample rate that is a multiple of 5, such as 5, 10, 15, 20, 30, 45, 60, etc. minutes.

Channel 1 will provide the total rainfall depth within the sample interval. It does so by multiplying the number of tips within the interval by the tipping bucket's calibration factor. The calibration factor is the amount of rainfall depth (mm, m, in or ft)/ tip. The calibration factor should be indicated on a label on the tipping bucket device or in the manufacturer's documentation. First choose the rainfall depth Unit and then input the Range from the following calculation:

Channel 2 does not require any setup or user input. The readings in channel 2 are of maximum 5 minute peak intensity within the sampling interval. This rainfall intensity value is derived by subdividing the sample interval into 5 minute sub-intervals and temporarily recording the number of tips in each 5 minute sub-interval. The Peak intensity reading is calculated by multiplying the number of tips in the 5 minute interval with the largest number of tips by 12 and presenting peak intensity/hr.

After the user has setup the Rain Logger, click the button to start logging. A Message Box will pop up to ask for confirmation. When logging the logging lamp on the Rain Logger will flash every minute.
