Configure data logging
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.
1. Push MENU.
2. Select Programming>Datalog Programming.
3. Select Channels Logging.
4. Select the sensor or logger.
5. Select a maximum of 16 channels.
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
normal operation. The secondary logging interval operates during alarm conditions.
Note: The primary and secondary logging intervals operate for all channels of a sensor or the logger. A logging
interval for an individual channel is not possible.
Configure the software totalizer
Pre-requisites: Program the instrument to record one or more flow channels in the data log.
The software totalizer counts the total flow volume for one or more flow channels. The user can set
the flow volume to zero if necessary.
1. Push MENU.
2. Select Totalizers>Software.
3. Select the sensor with the applicable flow channel.
4. Select Settings.
5. Select the options:
Option Description
Enable/Disable Starts or stops the totalizer.
Unit Sets the totalizer flow units. Options: gallons (default), liters, acre feet, cubic feet, cubic
meters.
Scaling Sets a multiplier for high or low flow rates. For example, if the totalizer flow shows (x1000)
465 gallons, the actual flow volume is 465,000 gallons. Options: x1 (default), x10, x100,
x1000, x10000, x100000, x1000000, x0.1
6. To set the totalizer to zero for a configured flow channel, select Reset.
Note: If channels are added to or removed from a program, the instrument erases all data from all channels
and totalizers (resettable and non-resettable). Make sure to download the data from the logger to a safe
location before the program is changed.
