Click on the green lock indicator to open a Field Edit Window. Enter the value in the for Auxiliary Multiplier and click on Write to LCR. If this value is set to zero, the Auxiliary Multiplier value will NOT print on the delivery ticket.
Configure LCR - Product Calibration Gross Quantity, Gross Preset Point Number Gross Quantity is a read-only field. It is not editable. The gross quantity of fluid measured by the meter during a product calibration prover run is represented here. This is covered in detail in the sections on Single-Point Calibration and Multi-Point Calibration. This field represents a point on the calibration curve for Multi-point Calibration. Up to 10 points on a curve may be calibrated for near perfect accuracy.
Configure LCR - Product Calibration Gross Total This field represents the cumulative, gross total for the product that is selected. Click on the green lock indicator to open a Field Edit Window and enter the Gross Total. Click on Write to LCR. Net Total This field represents the compensated, net total for the product selected. Click on the green lock indicator to open a Field Edit Window and enter the Net Total. Click on Write to LCR.
Single-Point Calibration Performing Single-point Calibration requires the use of a volumetric prover or other calibrated device with which to compare the meter delivery quantity against a standard. Since the rest of the Product Calibration information has been entered, this calibration procedure is ready to proceed. As describe on Page 28, Pulse/Unit represents the number of pulses that the LectroCount counts per unit of volume.
Multi-Point Calibration Multi-point Calibration allows a flowmeter to be used over a wide range of flow rates without experiencing a loss in measurement accuracy due to the inherent shape of the meter curve. This puts the Linearization algorithm into effect. If the error message ADJACENT POINTS OUT OF 0.25% RANGE is displayed, APPLIED will not take effect. The Linearization Points will need to be re-selected to ensure that no two adjacent points, based on flow rate, are more than 0.
Multi-Point Calibration Method 2 - Field Proving Technique In situations where the meter’s accuracy curve is not provided by the manufacturer, Multi-point Calibration must be performed by proving the meter at various flow rates. 11. Move the pointer to “Flow Rate” and press ENTER to open a Field Edit Window and enter the maximum flow rate observed during the run. Press ENTER. 12.
Diagnostics The Diagnostics screen is for viewing only. None of the fields are editable. Printer Busy? indicates that the print processor has begun to print a ticket. Diagnostics Delivery Status Pulser Faults represents the number of false or missing pulses detected during the last delivery. ROM Check? indicates if a delivery could not be started due to the checksum of the LectroCount program code space failing. Supply Voltage represents the current voltage being supplied to the system.
Diagnostics Data Access? indicates if a data access error occurred during a delivery which was critical to the delivery. New Delivery Queued? indicates that a new delivery has been queued in the LCR. This condition occurs when an "Run" command is issued and the switch is in the STOP, PRINT, or SHIFT PRINT position. Delivery Code Delivery Ticket? indicates that a delivery ticket is pending. A new delivery cannot be started until this field is cleared by successfully printing the last delivery ticket.
Security Position the pointer on “User Key” and press ENTER to open a Field Edit Window. After “User Key” has been programmed, the system can be UNLOCKED by re-entering the “User Key” password. Move the pointer to “Security” and press ENTER to open a List Box Window with the options LOCKED and UNLOCKED. To lock the system, move select LOCKED and press ENTER.
