ECAL CALIBRATION (Initial Reference)

With Essential Parameters (P0 through P7, and P21) programmed as required, select the ECAL Test

Reference (P20=1). Access P7 again, [PARAMETER 7E] is displayed. (The "E" indicates the P7 value

displayed is associated with the ECAL Test Reference).

Perform a Zero and Span calibration. (A Test Weight is not required as ECAL is automatically applied for

Span calibrations when P20=1). To obtain an accurate ECAL/belt scale signal correlation, perform a material

test. Refer to Parameters/P8 Span Adjust.

Upon the completion of the material test, the new ECAL Test Reference (P7E) value is automatically adjusted

so ECAL will accurately simulate material flow during future Span calibrations.

For best results, if the new P7E value is not between 50% to 100% of the Design Rate (P1) value, perform an

ECAL Adjust. Refer to Parameters/P22 ECAL Adjust.

ECAL CALIBRATION (Alternate Reference)

After the CompuScale III Span calibration is completed with a Test Weight (or Test Chain), ECAL may be

used for subsequent Span calibration checks. Using ECAL as a Secondary Reference is especially useful

when frequent Span calibration checks are required but using a Test Weight (or Test Chain) all the time would

be impractical.

Select the ECAL Test Reference (P20=1). Adjust ECAL to the value desired (P22=2). Factor the adjusted

ECAL reference to the current span. (P22=2 or P9). Refer to Parameters/P20 Test Reference Selection and

P22 ECAL Adjust.
