Testing the Connection From the Rain Gauge to the Field Unit
The Observant C3 or Solo will flash its input-port LED indicator for several seconds whenever a pulse is received from a rain gauge.
To test that your rain gauge is generating pulses and that the pulses are being "seen" by the field unit:
- Create a pulse by either pouring a small quantity of water into the gauge to simulate rainfall or removing the top of the rain gauge assembly and manually tipping the mechanism.
- If the field unit's port sees a pulse from the rain gauge, the input-port LED will flash for 3 seconds, indicating there is a working connection from the rain gauge to the field unit.
- If the LED doesn't flash, no pulse has been seen by the field unit (possibly the result of damaged cabling or a non-functional reed switch in the rain gauge).
Checking the Rain Gauge's Accuracy
- During installation, always check the base plate's bubble level to verify that the baseplate is level.
- Take 18.4 fl oz (544 ml) of water and pour it into the rain gauge slowly, over a period of two minutes. That should result in 1.00" (25.4 mm) of rain displayed in the Observant Global Monitor application within 30 minutes.
