Standardization & Calibration
Perform Calibration
5. Std Cycle Time: Specify the number of time constant periods used for
the standardization. If the time constant is 128 seconds and you enter 2
here, the standardization cycle will last 256 seconds (2 x 128 seconds).
6. Standardization on: Enter the number that describes how the
standardization will be performed: on a pipe full of carrier (1 ) , an
empty pipe (2), or a pipe full of process (3).
7. Start Data Cycle: Enter 1 to start standardization.
8. Once standardization begins, the time remaining will be displayed. You
can interrupt the cycle at any time by clicking
Abort .
9. When the time remaining is 0 seconds, click Next two times. The
software will display that the cycle has been completed. Click Write
Changes .
Perform
Calibration
The steps below describe how to calibrate the gauge.
1. If necessary, set up the gauge.
2. Standardize according to “Perform Standardization” .
3. Fill the pipe with process material at a density in the range of interest.
Keep the process density as stable as possible during the calibration
measurement, and be ready to take samples of the material during the
calibration cycle.
4. In the NI-FBUS Configurator, go to AI_TRANSDUCER > 3 Gauge
Calibration > GAUGE CALIBRATION.
5. When prompted, remove the loop from automatic control.
6. CAL Cycle Time: Specify the number of time constant periods used for
the standardization. If the time constant is 128 seconds and you enter 2
here, the standardization cycle will last 256 seconds (2 x 128 seconds).
7. Start Calibration Cycle : Enter 2 to begin the calibration cycle.
