The Status Bar is located at the bottom of the main screen. In all run modes, COMPASS flashes information
related to the current operation on this display. While running tests, two panels and a progress indicator
also display with status information on the current test step and point. The blue panel on the left displays
the current test step or function. Each point of a test sequence has five basic test steps:
molbloc Change (if specified for this point in Test Definition)
•
Purge (if specified for this molbloc change)
•
Leak Test (if specified for this molbloc change)
Set Flow to flow point specified
Stability Test for flow to stabilize at the set point
•
Tare (if specified for this point)
•
Jog Flow (if specified for this point)
Dwell for dwell time at the set point
Take Point for length of averaging time
The red panel displays the current test point during a test. The notation used is “current cycle. current
point <of> total cycles. total points per cycle”. Multiple readings per point information is not included in
this display. For example, if a 2 cycle 10 point test is executed, point 3 of the 1
st
cycle displays as “1.3 of 2.10”.
Refer to these displays to determine the new current point, when the <Skip Back> and <Skip Forward>
buttons are used.
The progress indicator is a visual indication of the relationship between the current test point and the
number of points in a test. The left side of the progress bar represents 0 progress and the right side
represents 100 %. Each step and reading of a test point increments the progress indicator. When
<Skip Back>
and <Skip Forward> buttons are used, the progress indicator also reflects the current position.

6.4 RUN MODES
Run mode describes the automatic execution function that COMPASS is in. Typically, instruments are polled
over their remote interface while in a run mode. The top of the main screen always displays the current
run mode. All run modes support the ability to log data to a data file.
COMPASS has four run modes:
1. Idle - No run mode is active. Menu items such is [Setup] can only be accessed in this mode. They
are not available in active run modes.
2. Run molbox - Activated by the [Run] , [Run molbox] menu option. This run mode is to work with the
molbox without a DUT and without a Test Definition (see Section 7.3).
3. Run DUT - Activated by the [Run] , [Run DUT] menu option. This run mode is to work with the
molbox and a DUT Definition, but without a Test Definition (see Section 7.4).
4. Run Test - Activated by the [Run] , [Run Test] menu option. This run mode is to run a Test
Definition on a DUT (see Section 7.2).
