power up - The settings of the totalizer are stored in non-volatile memory. Therefore, if the

totalizer is running (totalizing) when the meter losses power, it will begin to run again when

power is restored. The value of the totalizer is saved in non-volatile memory once every minute

or whenever the totalizer is stopped or zeroed. When the totalizer is running and power is lost,

the totalizer can loose a maximum of one minute’s data.

Changes to the totalizer settings are saved immediately to non-volatile memory so it is not

necessary to use the “Save Configuration” command to protect the setting. The “Restore Con-

figuration” command has no effect on totalizer settings. The “Restore Factory Configuration”

command will turn off the totalizer but it will not zero the totalized value.

lCD Display format - The totalized value can be display on meters equipped with an LCD.

See the “LCD Display Mode” section of this document for instruction an how to display the

totalized value on the LCD. When displayed on the LCD, the totalized value will be shown on

the top line of the display and the unit is shown on the bottom line. The totalized value will be

formatted in fixed notation for values up to and including 999,999. For values of 1,000,000 and

greater, the number is formatted in exponential notation. For example, the number 999,999 will

be displayed as 999999 and the number 1,000,000 will be displayed as 1000e3 (1000

3

). The

maximum totalizer value is 1000e34 (1000

34

). The totalizer will roll-over to zero after it reaches

this value.

Changing Selected PV or PV Unit - If the user changes the selected parameter or the prima-

ry variable (PV) unit in the “Primary Variable” dialog box, then the totalizer will be stopped and

the totalizer value set to zero. If the “LCD Display” mode is set to display the totalizer value and

the primary variable is changed to something other then volumetric, mass, or standard flow,

then the display mode will automatically be changed to display the primary variable.

Property tables are used to provide density and viscosity information over a wide range of tem-

perature and pressure. Accurate density and viscosity information is required to make accurate

flow measurements.
