pressed and the display is in the operate mode. Displays the most
significant frequency information in the frequency monitor mode.
2— THICKNESS/MASS GROUP
Indicates the deposited or etched thickness (mass) in the displayed units.
Also used for briefly displaying the monitor crystal’s frequency when the
xtal key is pressed in the operate mode. This group is also used for
displaying density (gm/cc) when in the program mode. Displays the least
significant frequency information in the frequency monitor mode.
3— STATUS MESSAGE GROUP
When illuminated, indicates that the shutter is open and if the specified limit
was exceeded.
4— TEST MODE INDICATOR
