General History
The Configure > History option allows data to be stored in the historical
database. Hourly and daily values are stored for up to 35 days. The historical
database can be configured to log only the values that need to be logged.
NOTE
History points setup in the Meter > History screen override history points
setup in the Configure > History screen. When configuring history points
ensure that the point is not already defined in Meter History.
1. Select Configure > History Points.
2. Select the desired history point to be configured in Select History
Point. The parameter currently configured (if any) for this history point
appears in the Value to Archive field.
NOTE
The first eight history points are reserved for use as Meter History; begin
selecting history points with History Pt. #9.
3. Click the TLP Value to Archive label to specify a point type and
parameter to be archived.
4. Select the Point Type to archive. To prevent this history point from
logging values, select Undefined as the Point Type.
5. Select the Logical Number. For example, select Analog Input AIN A 2.
6. Select the specific Parameter to log.

8. Choose the Select Archive Type to specify the exact archive type of
the history point. The archive type affects how the logged value is
calculated.
• Undefined – Point not configured
• Disabled - Point not configured
• Average - Minute values are averaged to compute the hourly
value. The flow inputs (such as DP) allow the user to select among
four types of averaging for calculating flow quantities or for
providing values. Refer to the Select Average Type parameter.
• Accumulate - The flow, energy, or uncorrected flow values are
summed over a specified time period to compute the value based
on what is selected in the Select Accumulation Time Basis. The
accumulation technique is used to acquire accurate accumulated
counts from an input for a specified time period.
• Current Value - Current sampled value is used for the hourly
value.
