The first Tooling is set in the Film Parameters Menu and is applied to the averaged Rate and Thickness for all sensors assigned to that film. Film Tooling is a film specific value.

The second Tooling Factor, xTooling, is set in the System Parameters menu. It adjusts the tooling for each individual sensor before it is averaged. xTooling for a sensor applies to all films. If the individual sensor xToolings are set properly, a sensor failure will not cause a jump in the average Rate and Thickness reading.

To adjust xTooling:

1.Press ProgramSubstrate to enter program mode.

2.Press PrevManual background to enter the System Parameters Menu

3.Press NextManual background until FRQ DISP is shown, then press the Control Knob .

4.Adjust the Control Knob to set the XTLTOOL 1 value

5.Depress the Control Knob to save the value and move to XTALTOOL 2 .

6.Repeat Steps 4-5 for each of the installed sensors.
