NOTE: NETFLOW (default) is best for applications where there may be zero flow for
long periods. It minimizes false Totalizer register increments due to data scat-
ter. Press the <Down Arrow> to accept the default setting.
To select a Totalizer Mode:
To access the [Totalizer Mode] option list press
Move the cursor to the required Totalizer mode by pressing

2.6.9 BATCH/SAMPLE TOTAL
The meter maintains a separate totalizer register for Batching or Sampling applications. Un-
like the Flow Total registers, you cannot access this register directly. It is used for re-
lay control only. If you assign the system relay to this function, a momentary (200 mS) relay
pulse occurs whenever the BATCHTOT register accumulates a specified liquid quantity. You
enter the total flow volume required to activate the relay, in the Batch/Sample Total menu
cell. The numeric entry must reflect the selected flow total units. The Totalizer Display Scal-
ing menu cell shows the applicable flow total units. The sign of the Batch/Sample Total deter-
mines positive or negative accumulations.
NOTE: The Batch/Sample total relay requires the same consideration for ex-
ceeding the maximum pulse rate as the TOTCNT relay (see Total Resolution).
To enter a Batch/Sample Volume:
To activate numeric entry press
Use the numeric keys to type the desired Batch/Sample TOT accumulation.

THE DATA SPAN/SET/CAL MENU
This menu becomes available after picking a Meter Type and Measurement Channel. How-
ever, some functions will only be active after the transducers are installed and operating
properly.
Use the [Data Span/Set/Cal] menu to set the range for analog outputs and setpoints for Alarm
relay outputs. Additionally, the [Calibrate Flowrate] menu allows you to apply external ad-
justments to the meter’s intrinsic primary outputs.
