You will enter all the weights, one at a time, in the text field next to the 

symbol. You will click the 

symbol to add a Gravimetric sample reading. The system will insert the value in the list box above 

and then average the values and calculate a new conversion factor based on the series. You have three 

options on how you wish to 

proceed with the calculation. 

• 

Apply 

– This will make the 

temporary change to the 

recipe for analytical 

purposes, but will not save 

the change to the recipe 

database. 

• 

Apply and Write Recipe 

– 

This will update the recipe 

database with the current 

recipe along with this new 

conversion value. 

• 

Cancel 

– will abort anything 

performed in this window 

and return you to the

HAT TO CHANGE AND HOW IT AFFECTS YOUR READING

 

Peak Tolerance

 

This is the amount of acceptable variation in percentage between the final estimated thickness by the 

peak analysis algorithm and the thickness displayed by the software. 

If a value of 0.2 is used in this field, then a 20% variation is acceptable between the calculated thickness 

by the software and the estimated thickness by the peak analysis. 

If the variation is more than what is acceptable as defined by the acceptance tolerance value, then the 

software will flag the measurement as a “No Read.” The typical range for this parameter is 0.1 to 0.5. 

Fringe Variance

 

This is the amount of variation allowed in thickness between the calculated thickness and individual 

peak estimates. (See Section 9 for an example of estimating thickness using peak estimate tool. In 

general, as a rule of thumb, this value should be set within 10 to 15% of the expected thickness. 

Depending on the nature of the samples and the quality of interference, this parameter might have to 

be modified. The typical range for this parameter is 0.1 to 0.5. 

Height Threshold

 

This is the minimum amount of height (distance from the bottom point to the top point for a given 

interference cycle) required not to consider the interference wave as noisy. If the peak to valley distance 

is less than the height threshold value, then that is not considered as a valid interference cycle. A typical 

value for this field is from 0.002 to 0.01.
