C.Operations[0].kFactStruct.FreqAtKFactor[4] Float REAL Freq[4] for KFactor [4]

C.Operations[0].kFactStruct.FreqAtKFactor[5] Float REAL Freq[5] for KFactor [5]

C.Operations[0].kFactStruct.FreqAtKFactor[6] Float REAL Freq[6] for KFactor [6]

C.Operations[0].kFactStruct.FreqAtKFactor[7] Float REAL Freq[7] for KFactor [7]

C.Operations[0].kFactStruct.FreqAtKFactor[8] Float REAL Freq[8] for KFactor [8]

C.Operations[0].kFactStruct.FreqAtKFactor[9] Float REAL Freq[9] for KFactor [9]

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

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.
