Set Baseline Wizard Tools Menu:
This allows you to select the direction to baseline and what data to use to perform the baseline.
Select baseline flow direction: Select the direction to baseline. You will need to rerun the wizard a
second time to baseline the other direction if this is for a bi-directional meter application. Whether
the baseline has been set or not will also be indicated next to the direction.
Select baseline data source:
Select one of the data sources:
1-minute averages from the meter - This is the preferred option when setting the baseline for
a new meter. The meter must be under typical flowing conditions when the baseline is set.
Upon click Next, the meter will verify the 1-minute averages from the meter are valid before
continuing to the next page.
Daniel MeterLink maintenance log - This option is intended to be used if the meter has
already been installed in the field for a period of time and a Daniel MeterLink maintenance
log is available from the initial startup that was taken during normal flowing conditions.
Upon clicking Next, you will be prompted to select the Maintenance log file to use. Daniel
MeterLink will verify this is a valid file and will gather as much data as possible from this file. If
the maintenance log does not contain certain values, you will have the opportunity to keep
the default values or manually enter your own.
Manual entry - This option allows you to manually enter data for each of the parameters. This
could be used to modify a single parameter for a baseline already set or it could be to enter
data from a historical record from when the meter was first put into service.
Signal Analyzer Wizard Meter Menu:
The Signal Analyzer Wizard is used to adjust the behavior of the meter's signal sampling and output
updates. This dialog is only available while connected to a meter.
