Wiring Guidelines This section gives information on the wiring of Kalyx-RG rain gauge. For most applications, the rain gauge may be connected directly to a pulse counting input (contact closure) on a data logger, but some care is needed if long cables are used. -
Page 9: Wiring For Internal Loggers
Wiring for internal loggers To connect an internal data logger or counter, two wires have to be connected to the green connector terminal block and taken to the contact closure input of your chosen logger. The Kalyx-RG includes a 2-way terminal for connection (the green terminal). As this is a contact closure (switch) device it does not matter which way you connect this to your logger or counter. -
