Important facts to remember –

• Equipment should be running at normal environmental conditions – temperature, pressure, process

flow, etc.

• Final gauge measurements can only be as accurate as your sampling and analysis technique.

• Remember to document all changes made to the factory parameters that are active in your system.

Density Low/Reference and High/Calibration

The density calibration correlates the detector counts to the density in the pipe/or vessel. This can be

achieved by two different methods. One method consists of Referencing on a know density like water.

Low Density Reference

PROCEDURE:

Using the Ronan local display or HART communicator find the Main Menu;

Scroll down until you reach and highlight Calibration.

Access Calibration by pressing the right arrow key.

Scroll down until you reach and highlight Cal Density.

Access the Cal Density by pressing the right arrow key.

Scroll down until you reach and highlight Low Reference.

Access the Low Reference by pressing the right arrow key.

Access the Reference by pressing the right arrow key.

Press the F4 key (OK) to the prompt ‘Warning – Remove loop from automatic control, verify that source Is

on, and the vessel/pipe is empty.’

Press the F4 key (OK) to calibrate the gauge. Gauge will count down until calibration is complete.

Scroll down until you reach and highlight Ref Density 0.0000 (Note 0.0000 value and units may very

depending on the what value and units were selected.) (Note: You must access the Ref Density and either

change or acknowledge the value to complete the reference.)

Access Ref Density 0.0000 by pressing the right arrow key.

Use the arrow keys to select and change the display value to the correct density. Once the displayed value is

correct, press the F4 key (Enter). ). The Low Reference is complete.

For an illustrated procedure, see the following pages.
