Calibration
2 Setting the high density and collecting Cal High data
You must:
• Use the gauge to measure the high process condition.
• Enter the actual density.
This sets the gain of the calibration curve. Perform this procedure before or
after setting the low density.
Before starting the Cal High data collection:

Check that the correct parameters (vessel inner diameter, engineering
units, measurement span, and source type) are correct.

Power up gauge one hour before start of calibration.

Fill vessel or pipe with high process or close the source holder shutter to
simulate high process.

Prepare to draw a sample while the gauge is collecting data.
