Scaling & Calibration (SCALCAL)
It is very important to read the following information, before proceeding to program the meter:
There is no need to recalibrate the meter for frequency in Hz when first received from the factory.
The meter is factory calibrated for Hz prior to shipment. The calibration equipment is certified to NIST
standards.
!
IMPORTANT
Performing a scaling or calibration operation will override
any k-factor programming. Similarly, completing the k-factor
menu will override any scaling or calibration performed on the
meter. Verify the method of programming required, use the
password protection feature to secure the meter if necessary.
There are three methods of programming the display to show the correct engineering units based on
input pulses.
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 calibrator or a flowmeter.
The k-factor, scale, and calibrate functions are exclusive of each other. The meter uses the last function
programmed. The Scale and Calibrate functions can use up to 32 points (default is 2). The number of
points should be set in Scale and Calibrate accordingly under the Number of Points (nopts) menu
selection prior to scaling and calibration of the meter, see page 54 for details.
This menu is used to scale and calibrate the meter. For information on using a k-factor for programming
the input, refer to Entering the K-Factor (Factr) on page 27.
Undoing K-Factor, Scale, and Calibration (Undo?)
Whenever the input programming is being changed from using k-factor to scaling or calibration; or from
scaling or calibration to k-factor, a confirmation menu appears. This prevents accidental changing of the
input programming.
The example below shows a meter programmed with a k-factor being reprogrammed to utilize input
scaling.
