2.3 NAVIGATING THE INSPEC DISPLAY
2.3.1 BASIC SCREEN LAYOUT
The InSpec display consists of a 20x2 LCD display. The display operates within several
modes. We will look at each of these briefly. The most common screen that an operator will see during
day-to-day use is the front display screen. This is the default screen shown during operation.
Figure 3 - InSpec Front Display Screen
The above front display shows the current value in the F_FLOW register, the associated flow
units and the current status of the controller is indicated as ‘Waiting’ by ‘WTG’ to the bottom left of the
display. Each application has a set of specific three letter abbreviations for each status condition of the
controller. These abbreviations will be listed and explained in the specific ‘status’ section of your
Sampler / Blender application manual.
In normal display mode, the front display shows one register value and its associated
configurable display title. This is ‘FLOW’ in the above example. There is also a configurable scrolling
feature and, at a user defined time period (in seconds), the screen will scroll through a series of up to
twenty-four defined register values. The scrolling mode can be turned on or off from the front display by
pressing the up cursor button. Items that appear in the scroll list are chosen and set up via the
‘Display→Display Setup→Scroll Setup’ menu item. To enter the menu press either the enter button,
the centre cursor button or the down button. You will see the following display.
Figure 4 - Entering The Menu
On entering the menu, you will see the current depth of the menu listed in the top left hand side
of the menu display. In the above picture number ‘1’ indicates that you are in the first level of the menu.
The X/Y indicator to the right shows that in this level, under current security conditions, there are 4 items
in level ‘1’ of the menu and we are currently on item ‘1’. The arrow indicator to the bottom right of the
display shows that there are more options available to the right which can be accessed using the right
cursor button. A left arrow can also be displayed when there are options to the left of the current
position. Note: The X/Y number indicators will vary depending on which application you are
running and what your current level of security is.
