Select a LOW sample that is the LESS THAN OR EQUAL TO the thinnest material to be measured.

Select a HIGH sample that is GREATER THAN OR EQUAL TO the thickest material to be measured.

1. At the Run Screen, set the Alloy to NONE.
2. At the Run Screen, set the Nominal Thickness to the LOW sample thickness.
3. At the Run Screen, Initiate a STANDARDIZE. If gauge displays "GAUGE LOCKED" it may be necessary to press UNLOCK GAUGE, then press INITIATE.
4. After standardize completes (gauge displays GAUGE LOCKED), navigate to the "Alloy Calibration" screen.

Note: Remainder of steps executed at Alloy Screen.

5. Touch the "Double Sample" button to enter this mode (button turns green).
6. To change an alloy name in the list: In the lower half of the screen, enter a name for the alloy to be calibrated.

• Touch a white "Alloy Name" box.
• Touch the "Change Name" button
• The alpha / numeric keypad is activated.
• Use the touch screen alpha / numeric keypad to enter the desired alloy name.
• Touch the "Accept" button to store the name.
• The newly entered name will now appear in the Alloy Name list.

7. Use the "Alloy Select" panel (list) to specify the alloy to calibrate.

• You may use the "Next" and "Prev" page buttons to locate your alloy name if required.
• When you have located your alloy, simply touch it and it will be displayed in the Alloy Select box.

8. Use the "Nominal Select" panel to enter the thickness of the LOW sample.

• Touch the "Thousandths" pad.
• A keypad screen will appear.
• Key in the sample thickness in thousandths.
• Touch the green "Enter" button to complete Nominal Thickness entry.

9. Insert the LOW sample over the X-ray port and touch the "Find Low Alloy" button.
10. A yellow "Abort" button will appear adjacent to the "Find" button.

11. When the gauge has determined the correct multiplier for the low sample, the yellow "Abort" button will turn green and display an "Alloy Found" caption.
12. Use the "Nominal Select" panel to enter the thickness of the HIGH sample.

• Touch the "Thousandths" pad.
• A keypad screen will appear.
• Key in the sample thickness in thousandths.
• Touch the green "Enter" button to complete the Nominal Thickness entry.

13. Insert the HIGH sample over the X-ray port and touch the "Find Hi Alloy" button.
14. A yellow "Abort" button will appear adjacent to the "Find" button.
15. When the gauge has determined the correct multiplier for the high sample, the yellow "Abort" button will turn green and display an "Alloy Found" caption.
16. The alloy calibration for this alloy is now complete.

In situations where only one sample is available, a multiplier derived from a single sample (preferably mid-range) can be applied over the entire gauge thickness range with less than optimum, but generally acceptable, results.

The procedure for establishing the correct alloy compensation in the single sample mode differs only slightly from the double sample mode. That is to say, that at the beginning of the procedure (Step 5), touch the "Single Sample" button to enter this mode and in Step 9, touch the "Find Sample Alloy" button.
