C.Operations[0].SampleTime Float REAL Sets time for a sample to be taken.
(2.0 second maximum sample time for high resolution
frequency mode and 5.0 second maximum sample
time for totalizer mode)
0.033
C.Operations[0].HighestAllowedFreq Float REAL User-defined value between MinDetectableFreq and
120,000
When the frequency reaches this level, it sets the
Overspeed alarm limit
3700
C.Operations[0].AccelAlarmValue Float REAL Sets Acceleration alarm limit
-Maximum acceleration (cycles per second
2 )
<AccelAlarmValue< +Maximum acceleration (cycles
per second
2
)
100
C.OutputSetup[0].TriggerOn Decimal SINT Sets when output 0 energizes
0 = No Action
1 = Frequency
2 = Acceleration
3 = Full Flow State (N/A in this mode)
4 = Trickle Flow State (N/A in this mode)
5 = Prover Run State (N/A in this mode)
6 = Prover Range State (N/A in this mode)
0
C.OutputSetup[0].TieToCounter Ties a channel to output 0
0 = No connection
1 = Connect Channel0 to Output0
2 = Connect Channel1 to Ouput0
0
O.Total[0].CombinedCorrectionFactor Float REAL 0 = Default value of 1.0
Use this value to convert from Hz to RPMs. Results
are displayed in Frequency Average only
60
O.Total[0].Overrange Decimal BOOL Enables the Overrange alarm on output connected to
channel 1. When the Frequency Average exceeds
100KHz, this alarm is set.
0 = No Alarm
1 = Alarm Enabled
0
