First, change the name “Digital Pulse” into a more comprehensive one. We use “Rain” here.
The menu-
item “pulses per unit” is very important and converts the input pulses into a physical value.
It is advised to test the hardware first, before proceeding to selecting the right settings for bucket-size etc.
Therefore, leave this value (1) and test your sensor first.
To test, just connect it, and apply a known amount of pulses tot the data logger. You can verify this count
with the command
<Ctrl>A<Shift>V<Ctrl>D
When this is correct you can proceed to set up your
rain-gauge.
Now you have to enter the physical details of your rain-gauge.
