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. (Pulse input models only.)
• 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 79 for details.
PD6310 Only: 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.
