RATE / TOTAL screen
The RT/TO screen shows both the flow rate and total values in programmed engineering units. If the
linearizer is active, ‘LN’ shows in lower left corner. If the Gate Time filter is active, ‘GT’ shows in lower
right corner. Pressing the
RESET button resets the total value back to zero (0). The Total can also be
reset remotely by connecting a momentary voltage to the external RESET pin.
GRAND TOTAL screen
The GRAND TOTAL screen displays the flow total in programmed engineering units. The GRAND TOTAL
value does not reset when the TOTAL value is reset and is therefore often used to collect a day total in
batch applications. To reset the GRAND TOTAL a password is required. The password is 53126. This
password cannot be changed.
STATUS screen
The STATUS screen shows multiple values and is used more as a summary screen, especially if trouble
shooting a system. The following values are shown:
1. The output state of Limit 1 and Limit 2
2. The flow rate in un-scaled units of Hertz (frequency). NOTE: The Gate Time filter and linearizer,
if active, do not affect the flow rate value in the STATUS screen. This is the raw incoming
frequency.
3. The total value in un-scaled units of Pulses.
4. The analog output in milliamps (mA). NOTE: Because the mA value is an actual signal output,
it is affected by the Gate Time and linearizer, if activated.
