Product #
– A list box containing the 16 products that are available for setting up and
calibrating the LCR.iQ.
NOTE:
·
Products 1-16 are available for setup. Only setup and calibrate products that are to be
used by the LCR.IQ.
The LCR.iQ provides two means of calibration, single-point [Calibration screen (1/4)] or multi-
point calibration [Calibration screen (4/4)].
A “point” corresponds to a particular flow rate along the meter linearity curve. Single-point
calibration adjusts one point along the linearity curve to zero percent error—typically at a flow
rate representative of a normal delivery. Since meter linearity varies at different flow rates,
and every meter behaves differently, the more points of calibration will generally result in more
accurate fluid measurement.
Multi-point calibration zeroes the percent error at multiple flow rates (between the rated
lowest flow rate and highest flow rate of the meter) in order to zero-out the linearity curve
across the rated flow range.
To multi-point calibrate the meter using the LCR.iQ (Calibration screen 4/4), first select point
#1 and enter the lowest flow rate measured. Then, enter the % error measured at that flow
rate. Repeat this for points 2 through the highest number of points measured (up to 16 points
available).
Linearization Mode
– A list box for applying a multi-point calibration. Setting this field to
Applied
will activate multi-point calibration–if all parameters are met for using multi-point
calibration.
Linearization Prover Qty
– A numeric only text field for performing a multi-point calibration on
the currently selected product on the LCR.iQ. This field is used during multi-point calibration to
enter the known prover quantity of a volumetric proving device or master meter. Following a
multi-point calibration run, entering a value into this field will automatically prompt the user to
select a point to apply the run to, followed by a prompt to enter the flow rate that was used
