Set LO FLOW
CUTOFF Limit
Select TOTALIZER MODE
(auto or manual reset)
☞
This feature enables you to establish a measured low flow
rate at which the displayed value becomes zero (and any
representative analog output becomes minimum value).
This “cutoff limit” can be between 0.1% and 10.0% of range.
Example: Suppose your flow rate range is set up for 0-200
GPM. If you want the cutoff to be at 20 GPM, you must set
the LO FLOW CUTOFF limit at 10.0%. This will provide a
reading of zero whenever the measured flow rate decreases
below 20 GPM.

The totalizer is factory-set for automatic reset, which resets
the displayed volume to zero after reaching its maximum
limit. After automatically resetting, the totalizer starts a new
count. Conversely, the totalizer can be set to a manual reset
mode to preserve the total volume. In the manual mode, the
totalizer can be manually reset back to zero at any time by
using the “RESET VOL” function in the TEST/MAINT menu.
NOTE:
When line power is lost, counting is suspended re-
gardless of totalizer reset mode. After power is
restored, counting resumes from the suspended
value.
