3.4 Application Example
3.4.1 Connecting the Product to a Rain Gauge
The following shows the procedure for connecting the
3639-20 PULSE LOGGER to a rain gauge for the
measurement of precipitation.
(1) If the product is being used for the first time or the
batteries have just been replaced, set the current time.
(2) Connect the 3639-20, 3911-20, and PC, and set the
filter to "For mechanical contacts" (default setting)
using the application software.
To output an alarm signal, set Alarm Output to ON and
specify an upper-limit value (default setting: Alarm
Output OFF).
(3) Make other settings (recording interval, etc.) as
necessary.
(4) Connect the rain gauge to the 3639-20. The 9629
CONNECTION CABLE can be cut to any desired
length. If the cable is cut, remove the sheath using a
wire stripper prior to use. Regarding connection of the
rain gauge and the 3639-20, refer to the operation
manual for the rain gauge.
(5) Start measurement.
The 3639-20 is not waterproof. Therefore, place the unit
inside the rain gauge or at a location where it is
protected from the rain.
(6) Upon completion of measurement, use the 3911-20 to
transfer the recorded data to the PC (see the "3911-20
Instruction Manual").
