Input Calibration Method (
InCAL
)
There are three methods of calibrating (or scaling) the display to show the correct engineering units.
•
Use the
Factor
menu to enter a K-Factor.
•
Use the
Scale
menu to enter the scaling without a signal source.
•
Use the
Calibrate
menu to apply a signal from a signal source.
Note: The K-Factor, Scale, and Calibrate functions are exclusive of each other. The meter uses the
last function programmed. Only one of these methods can be employed at a time. The Scale and
Calibrate functions can use up to 32 points (default is 2). The number of points should be set for
Scale and Calibrate accordingly under the Number of Points
(
nopts
)
menu selection prior to scaling
and calibration of the meter, see page 55 for details.
K-Factor Calibration (
Factor
)
The meter may be calibrated using the
K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the
K-Factor
(
Factor
) menu and select the decimal point with highest
resolution possible and program the k-factor value (
i.e.
pulses/gal). The meter will automatically calculate
the flow rate using the k-factor and the time base selected.
