Test Rate (Flowmeter Applications Only)
Defines the desired Rate to be registered by the Compu-M when the Test Weight is applied to the flowmeter.
Refer to the associated flowmeter instruction manual for assistance with calibration procedures, and Test
Weight or Test Rate calculations.
Enter the desired Test Rate as determined by the preceding calculation.
Entering "0" or performing a Reset will restore the Test Rate to the 100% Design Rate default value.
enter: Test Rate, as determined, (F = 100% Design Rate)
P8 Manual Span Adjust
Permits span calibration error correction, and automatically adjusts the current Test Load/Rate value.
This is accomplished by performing material tests and entering the span error (in percent). Refer to the
appropriate Belt Scale Applications or Flowmeter Applications section for instructions.
enter: % Span Error, (as determined).
P9 Factoring
Establishes the Test Load/Rate (P7) value of the applied calibration reference, based on the current Compu-M
Span calibration.
This feature may be used, to establish the Test Load/Rate (P7) value of a new or otherwise unknown Test
Weight, based on the Compu-M Span calibration results obtained from the old Test Weight.
Before initiating the Factoring process:
» Access the Test Load/Rate (P7) parameter and record the display value associated with the
Test Weight(s) used to perform the current Span calibration.
» Stop the material flow. (For belt scales, the belt must be running empty.)
» With the Test Weight(s) removed, perform a Zero calibration.
» Apply the new Test Weight(s).
During the Factoring process, the current Span count is displayed momentarily.
If [P9 E6] is displayed, refer to Programming/Display Messages.
When Factoring is complete, the Test Load/Rate (P7) value of the new Test Weight(s) is displayed. Copy the
new P7 value to the Programming Chart.
Ensure the appropriate Test Load/Rate (P7) value is entered, before performing subsequent Span calibrations
with the old or new Test Weight(s).
enter : 0 = Factoring not required (F)
1 = initiate Factoring procedure
