The display is able to show a maximum of eight characters, including the decimal point.
For all totalizer values configured as display variables, the position of the decimal point on
the display is fixed to the configured precision of the display variable.
When the totalizer reaches the largest value that can be displayed in these circumstances:
• The digits roll over.
• The decimal point does not move.
• The number of digits on the display does not change.
• The internal totalizer is reset to 0.
For example, the value 99999.999 rolls over to 00000.000.
Tip
If you are not sure whether or not the totalizer value on the display has rolled over, check the value
by using another method to read the current data.
Notes
• The mass and volume totalizers do not necessarily roll over at the same time.
• This feature does not apply to inventories. The display presents large inventory values in the
standard manner.
10.1.3 Effect of the Weights & Measures application on process
measurement and outputs
When the Weights & Measures application is installed, process measurement and
reporting is modified to prevent unauthorized use of the data. Specific changes are
controlled by whether the transmitter is secured or unsecured.
Transmitter outputs and process data when Approvals= NTEP Table 10-3:
Function Transmitter status
Unsecured Secured
Outputs mA output behavior If reporting a flow variable, mA output reports
zero flow. Otherwise, normal. Normal
Frequency output behavior Inactive (produces no pulses), even under fault
conditions
Normal
Discrete output behavior Normal Normal
Process variables All flow rates Reported as zero Reported normally
Density Reported normally Reported normally
Temperature Reported normally Reported normally
Totalizers Values Do not increment or decrement Increment normally
Inventories Values Do not increment or decrement Increment normally
Operate the transmitter with the Weights & Measures application
