4.2.5.3 Changing the Pulse Ratio
NOTES: The following table shows the setting for units without price displays. Units with price
displays will look slightly different as they typically utilize all three displays.
The Pulse Output mode cannot be used in conjunction with the serial communication
interface.
Follow the step by step instructions below to change the pulse ratio from 100:1 to a
different ratio.
When the pulse output ratio is changed, the display resolution is automatically adjusted to
match the pulse output resolution so that a higher resolution is not implied at the
dispenser than what is being recorded by the fuel management system. For example,
when the pulse output ratio is set to 1000:1, the volume display shows three decimal
places. When the pulse output ratio is 100:1, the volume display shows two decimal
places.
