Fixed Key: Zero Key - Active during runtime screen only.
ZERO
- This fixed key zeros the thickness number used and displayed by the STC-2000A.
Pushing the ZERO key stores a new zero reference for the sensing crystal. Any mass from previously
deposited materials is subtracted from the new thickness calculations. Zero thick on 3
rd STATUS key press
does not zero the calculated thickness, but is used as a setup/diagnostic to zero the value from the sensor
card.
Fixed Key: Manual Key
MANUAL
- Used to enable/disable the manual control of power. (See Section 2.8) This fixed key
toggles the use of the manual power pendent. When in manual phase, the Automatic rate control of the
STC-2000A is inactive, the control voltage to the deposition source can be increased, decreased or set to ‘0’
(STOP) with the pendent buttons. Pressing the pendent up and down buttons simultaneously will zero the
control voltage without aborting the run. The MANUAL key is only active after a film has been started and
during RunTime screen and other screens available through the STATUS key only. When you leave
MANUAL power control by pressing the MANUAL key a second time, the STC-2000A goes to the
Deposit phase of the film program without zeroing the thickness reading (see Section 2.8). The pendent
STOP button is functional only in the MANUAL mode.

NAVIGATING THROUGH STC-2000A MENUS
Menu Tree
An overview of the main programming menus and screens is shown in Figure 7.3. The keys to navigate
from menu to menu are shown in screenlike boxes with arrows to a general function category. [These
boxes are not meant to be true LCD depictions.] For example, to display the Main Menu while on the
RunTime screen, the fixed front panel MENU key is pressed, to display the Review Film Menu while on the
Main menu screen, the Review Film key is pressed. Refer to Figure 8.3. on the next page.
In the next section, the RunTime Screen and the information and data that appears on it will be
described. The STATUS key returns the RunTime screen from any programming menu location (1 st key
press). When the RunTime screen is displayed, pressing the STATUS key will invoke three other
consecutive screens as described in the previous section.
The Sequencing mode is fully described in the menu tree whereas only the non-sequencing mode
differences are shown.
Please note that the text boxes of the following menu tree are not meant to be true LCD screen
depictions.
