4.4.4.4 Frequency
In this Main Display mode the left-hand display is used to display the crystal
frequency in Megahertz while the right hand display is used to display the crystal
frequency in Hertz. This allows for display of the total crystal frequency to a
resolution of 0.1 hertz.
4.4.5 Parameter/Status Display modes
The Parameter/Status display serves a number of purposes. It is used to view and
modify parameter values, or to display monitor status or to display a user selected
variable. In the event of a warning condition or a failure condition, a descriptive
message will be flash alternately with the selected display.
When any of the arrow buttons are pressed, the display is used to show the value
of the previously selected parameter. Pressing one of the Probe buttons results in
the display of that probe's status alternating with the plating rate on that probe. If
the Status button is pressed, then the display cycles through a list of items, which
describe the status of the monitor. When the Probe or Status buttons are released,
or if the arrow buttons remain inactive for 30 seconds, then the display reverts to
one of the six displays described below. The 30-second hold of the parameter
display can be terminated early by pressing and releasing any of the Probe or
Status buttons.
4.4.5.1 Status Display
In the Status Display mode, the monitor state is displayed.
4.4.5.2 Frequency Display
In the Frequency Display mode the frequency is displayed as an eight-digit
number with a resolution of 0.1 hertz.
4.4.5.3 Elapsed Time Display
This display mode displays the time that has elapsed since the beginning of the
current state. I.e., if the current state is the Plate State then the time displayed is
the amount of time that has passed since the start of the Plate State. The time is
displayed in hh:mm:ss format.
4.4.5.4 Time to Go Display
This display mode displays the estimated time required to complete the current
state. In the case of the Plate State, the time to go is calculated by dividing the
difference between the Endpoint thickness and the current thickness by the
average rate.
4.4.5.5 Current Density Display
This display mode displays the current density at the probe electrode. The units
are Ampere per square decimeter for monitors with metric unit display and
Amperes per square foot for monitors with English unit display.
