Digital pulse counter example
Using pulse counting, Custom Scaling Factor, Custom Scaled Sample Unit, and a time range, the
digital pulse counter provides the appropriate measurement for your environment. The following
equation shows how pulses are converted:
Pulses between reporting intervals x Custom scaling factor (in Custom Scaled Sample Unit) =
n
reported measurement
Pulses between reporting intervals: Number of pulses between reporting intervals, which is
n
based on report settings in Remote Manager (see
Custom scaling factor: Refer to your sensor's manufacturer specifications for this value.
n
Custom scaled sample unit: Unit of measurement for your application.
n
Reported measurement: Reported value in the unit of measurement for your application.

For example, we want to measure rainfall in inches using a rain gauge with a digital pulse counter. The
manufacturer specifications for our sensor state that 1 pulse equals 0.011 inches.
We configure Digi Connect Sensor+ to send reports to Remote Manager every hour. Digi Connect
Sensor+ reads 100 pulses from 11:00 to 12:00.
The digital pulse counter device reports a rainfall amount of 1.1 inches between 11:00 and 12:00.
The following image shows how you would enter this example into the Digital: Pulse Counter settings
in Remote Manager.
