All data and alarm logs for all channels are erased in the logger when channels are added to or removed from a
program. Make sure to download the data from the logger to a safe location first, then change the program.
Use the Programming menu to set the channels to record in the data log. A channel can be a reading
from an attached sensor (e.g., level, flow, temperature), the battery voltage from a backup battery or
a statistical value based on a sensor reading. Data logging starts only when a channel is selected.

Note: The port number where the sensor connects to the instrument shows in the sensor channel name. For
example, Velocity 2 is the velocity channel name for the sensor that connects to sensor port 2. An IO number
that follows a channel name identifies the analog inputs of the optional I/O module.
6. Select Save.
7. Select Back>Logging Intervals>sensor or logger to set the logging interval.
8. Select the primary and secondary logging interval. The primary logging interval operates during
