High Calibrate (Continued)
PROCEDURE (Option 3)
An alternative to calibrating with process material is to use an absorber plate. The procedure is much the
same as that used for a process calibration, the only difference is that instead of material being placed on the
belt, the equivalent absorber plate is inserted into the space provided and the value assigned to the plate is
used as the calibration value. This value is determined after the scale has been commissioned on process.
Once the weigh scale has been calibrated by option 1 or 2, the conveyor is then run emptied and the
absorber plate is inserted into the space provided. The value displayed from the X96S Weight (lb/ft) is
recorded and also is marked on the absorber plate. This value will be the absorber equivalent weight.
Insert the absorber plate into the space provided. Run the conveyor empty at normal operating speed
during the high calibration.
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 Weight.
Access the Cal Weight by pressing the right arrow key.
Scroll down until you reach and highlight High Calibrate.
Access the High Calibrate by pressing the right arrow key.
Access the Calibrate by pressing the right arrow key.
Press the F4 key (OK) to the prompt ‘Warning – Remove loop from automatic control
before doing the calibrate procedure’.
Press the F4 key (OK) to the prompt ‘Verify that source is on, detector output is correct, and process is in
calibrate condition’.
Wait until the prompt changes from
‘Performing Calibrate procedure’ … to ‘calibrate SUCCESS. Remember to enter weight of the
material’.
Press the F4 key (OK).
Scroll down until you reach and highlight Cal Weight 20.0000 lb/ft. (Note 20.0000 lb/ft value and units may
very depending on the what value and units were selected.) (Note: You must access the Cal Weight and
either change or acknowledge the value to complete the High Calibration.)
Access Cal Weight 20.0000 lb/ft by pressing the right arrow key.
Use the arrow keys to select and change the display value to the correct weight that the absorber plate
represents. Once the displayed value is correct, press the F4 key (Enter). ).
Verify the status screen is displaying the correct weight. If not repeat the calibration procedure again.
Once the high calibration is finished, do not forget to remove the absorber plate. Make sure you store
away the absorber plate for future calibration.
The High Calibrate is complete.
The Mass Density Calibration is complete.
