Rate/Totalizer/Batch Controller Features
RATE DISPLAY
INDICATION
LED labeled “R” in lower right illuminates when meter is
displaying rate or process input.
LOW-FLOW
CUTOFF
Any input below the low-flow cutoff value will result in a display
of zero. May be set from 1 count to 100% FS, user selectable.
To disable low-flow cutoff, program cutoff value to zero.
Totalizer is based on rate display. So, inputs below the low-
flow cutoff value will not affect the totalizer.
ALTERNATING
DISPLAY
Display may be programmed to alternate between rate and
total every 10 seconds.
TOTAL DISPLAY
0 to 999,999, automatic lead zero blanking

POINT
May be set in any of the following positions: 9.99999, 99.9999,
999.999, 9999.99, 99999.9. Total decimal point is independent
of process/rate decimal point.
