C.Operations[0].kFactStruct.FreqAtKFactor[10] Float REAL Freq[10] for KFactor [10]
C.Operations[0].kFactStruct.FreqAtKFactor[11] Float REAL Freq[11] for KFactor [11]
C.Operations[0].kFactStruct.FreqAtKFactor[12] Float REAL Freq[12] for KFactor [12]
C.Operations[1].OperationalMode Decimal SINT Sets the module’s operational mode.
0 = OFF
1 = Totalizer Mode
2 = Non-Resettable Totalizer Mode
3 = High Resolution Frequency Mode
C.Operations[1].FilterControl Decimal SINT The following values placed in the appropriate word
invoke the following filters.
0x01 = Hardware (sub 100Hz RC) filter for F1
0x02 = Hardware (sub 100Hz RC) filter for G1
0x03 = 2 Hardware filters (sub 100Hz RC) for F1 and G1
0x04 = Firmware filter, 1 second debounce filter used for
prover applications for G1 (ignore/disable the gate for 1
second after an initial pulse)
0x06 = both the Hardware and Firmware filters for G1
0x07 = all filters above: Hardware (sub 100Hz RC) for F1
and G1 and the Firmware, 1 second debounce on prover for
G1
C.Operations[1].MeterSamples Decimal SINT
C.Operations[1].ThresholdControl Decimal SINT Sets module threshold control
0 = 50mV threshold
1 = 1.3V (TTL) threshold
2 = 4.0V threshold
C.Operations[1].CalculationType Decimal SINT Sets calculation type
0 = Counts/K-factor x MeterFactor correction x CCF
1 = Counts/K-factor x MeterFactor correction x AGA 7
compensation of CCF if CCF is not equal to 0.0
C.Operations[1].AccelCalculation Decimal SINT Number of past samples to use to calculate an
acceleration value.
C.Operations[1].FillMode Decimal SINT Sets the Trickle mode for engineering units or time.
0 = Engineering units
1 = Time
C.Operations[1].MinDetectableFreq Float REAL User-defined value from 0 - 100,000.
Sets FreqAverage, FreqPeriod, Speed, GrossRate, and
NetRate reading to 0 when calculated value is less than
value entered. GrossVolume, and NetVolume do not
increment below this value even though TotalCounts
increments over time.
