4. DETAILED OPERATION
4.1 INTRODUCTION AND GENERAL CONCEPTS
Basic operation of the PM-700 monitors is straightforward but the many options
and operating modes available through the programmable parameters may appear
overwhelming on first glance. We believe, however, that once the basic operating
concepts are understood, operation of the system will be experienced as
straightforward and intuitive.
In order to facilitate a rapid understanding of the PM-700's basic operating
concepts, we have seen fit to describe the operation in terms of modes and states.
The monitor has a number of operating states and modes, which are described
below. In addition, the probes themselves have their own states and modes, which
may be different than those of the monitor.
For example, the monitor may be operating in the electroless plating mode; the
measurement mode might be single probe, with sampling. The monitor might
then be in the Plate State (as opposed to the Ready, Preplate, or EndPoint states).
Meanwhile the probe might also be in the Plate State or alternately in the Hold
State if the monitor is between samples. If the monitor supports dual probes, then
the second probe will likely be in the hold mode or it could be in the failed state if
the crystal is being replaced.
The monitor is shipped from the factory with default settings for all parameters so
that no more than a few parameters must be setup to begin operation.
4.2 DISPLAYS
There are five display windows in the plating monitor front panel. On the upper
left most and upper right most are the Probe Status windows. Each contains three
indicator LED's. Note that in the PM-700, only the left status window is utilized
since PM- 700 supports single probe. Located in- between the two Probe Status
windows is the Rate and Thickness displays. Each contains four large numerical
LED's for easy readout of monitor measurements. Below the Rate display is the
Parameter/Status display. This is an 8 character alphanumeric display used for
parameter programming, viewing and editing. It is also used for displaying the
monitor status or other functions. See Figure 3, page 6.
4.3 BUTTONS
There are twelve membrane push buttons on the plating monitor front panel. The
four left most buttons are used for parameter viewing and editing, and the eight
right most buttons are monitor operational buttons. Their uses are described
below.
