Rate Mode Programming
Program the Rate parameters from the RATE display screen. To view the RATE Display Mode, use the
DN/MODE button or magnetic switch.
Time Base for Rate
Press and hold ENT button or activate and maintain the ENT magnetic switch for three seconds until the
display indicates T‐base (briefly) followed by the currently programmed time‐base. The default is 1 SEC.
Use SEL to select whether the rate is displayed in engineering units per:
1 SEC 60 SEC 1 HOUR 1 DAY
When desired Time Base appears, use ENT to record selection. The display (briefly) shows G‐TIME
followed by the currently programmed Gate Time value.
Gate Time
This variable sets the sample time on the incoming frequency for the RATE display and analog output.
The Rate display and analog output is based on the number of pulses counted during a prescribed “gate
time” period and updates at the programmed “gate time” interval. Increasing the gate time interval
produces a filtering or averaging effect useful for stable display and output of uneven or intermittent
flows. Gate Time is always programmed in seconds and the minimum Gate Time is 1 second. The default
