D.6 Density curve trim

Density curve trim is used to bring transmitter output closer to reference values. Density curve trim

can be used for standard curves, custom curves, and user-defined curves. Density curve trim is an

optional procedure.

To trim a density curve:

1. In the

ED Setup window, click on the Show Advanced User Options button. The window

shown in Figure D-3 is displayed.

Figure D-3 ED Setup window – Advanced user options

2. Select the curve to be trimmed.

3. For the configured derived variable (mass concentration, density at reference temperature,

etc.), compare transmitter data with laboratory samples at a few temperature and concentration

points.

4. Calculate the slope and offset required to bring the transmitter output closer to the laboratory

values.

5. Enter the slope and offset values in the

Trim Slope and Trim Offset textboxes.

6. Click

Apply.
