P26 MULTISPAN

Defines the calibration result to be used for subsequent measurements. Range = 0 to 8.

This feature may be used to store the Span calibration results associated with different operating conditions,

(e.g. change in conveyor incline, when an incline compensator is not utilized).

To perform a Span calibration for a specific operating condition:

a)Select the Multispan number to be associated with the current operating condition.

b)Enter the Test Reference value (P7) for the Test Reference selected (P20).

c)Perform a Zero and Span calibration. (If a Zero was performed recently, just perform a Span).

d) Perform a Span Adjust (P8) or Factoring (P9), as required.

To recall the calibration result (when the associated operating condition is re-encountered), select the

appropriate Multispan number. The MultiSpan number may be selected by providing one or more temporary or

permanent closed contacts between the TB1 COM (e.g. TB1-37) and the following TB1 terminals:

O = contact open

C = contact closed

For convenience, the Multispan number selection may be provided by a BCD switch connected to the

appropriate TB1-38,39,40,41, and COM contacts.

Alternatively, the Multispan number may be selected via the keypad. If "0" is entered, the MULTISPAN field of

the display is blank and Multispan 1 is utilized.

enter: desired value, (TB1-38,39,40, and 41 contacts must be open), (F=0).

P30 CALIBRATION DURATION (Belt Revolutions)

Defines the number of belt revolutions used for Zero and Span calibrations, Factoring (P9), and for Verification

Totalizer (P31) operation. Range = 0.01 to 99, (decimal values may not be used for verification totalizer

operation.

A low value reduces calibration time, while a high value increases calibration accuracy.

enter: desired value, (F = 1)
