Decimal Place
A decimal place can be inserted into the spoken message for a totalizer. Five decimal
locations are available:
XXXXX.
XXXX.Y
XXX.YY
XX.YYY
X.YYYY
When the message is spoken, the digits to the left of the decimal (represented by X) and
the digits to the right of the decimal (represented by Y) are spoken with the word ‘point’
between them. The format with the decimal at the far right with no ‘Y’ component is
spoken without the word ‘point’.
Default Decimal Place: no decimal place spoken.
Clear Code
The Clear Code is used to clear the totalizer to a zero reading. When the code is
received, the Cv2 announces that the point has been cleared. The code can consist of 1
to 7 digits and may use any of the 16 DTMF digits including A, B, C, and D.
Default Clear Code: empty string - no code.
Units
If you require the Cv2 to speak engineering units after the numeric value of the
Totalizer, set them in the Units section. Units are subdivided into three components
-- Prefix, Unit and Suffix -- as shown below:
Prefix Unit Suffix
NONE NONE NONE
THOUSAND CUBIC METERS PER DAY
MILLION CUBIC YARDS PER HOUR
MILLI CUBIC FEET PER MINUTE
CENTI PSI PER SECOND
KILO POUNDS
MEGA METERS
GIGA RPM
GALLON
BARRELS
PERCENT
PARTS PER MILLION
Select from the three columns to construct a phrase describing the units for the point.
One, two or three of the selections can be used; if all are set to NONE then nothing will
be spoken after the numeric value.
Default Units: for all three sections is NONE.
Analog Point
Analog points generate alarms when the input value exceeds either the low or high
setpoints. Like Digital and Watchdog points, they have Alarm State and DTMF Tag
settings. The other settings in the Analog Point dialog box are unique to this type of point.
Calibrate
Calibration of an analog allows the conversion of the input voltage reading to a value
that is expressed in engineering units. Setpoints are then assigned to the actual
corresponding measurement, and when the point is interrogated, the reading is
