Add or remove a test point while editing a test definition?
In the Test Definition
<Points>
Table, double clicking any test point automatically removes
it from the test point list. All subsequent test points are shifted up. To add a test point
press the
<Insert>
button and drag the pencil icon to the point location to insert. All test
points will shift down leaving an opening to enter a new test point (see Section 9.5.2).
Change the resolution with which the reference and/or DUT readings are displayed
while running and recorded in the Data File?
DUT resolution is determined in the DUT Definition (see Section 9.5.8). To change the
DUT resolution, edit the DUT
<Range>
tab. Select both the
<Flow>
and
<Output>
resolution that are appropriate for the DUT. By default reference resolution is one digit
greater than the specified DUT resolution.
Run an automated test if my computer has only one COM port and the molbox
reference and DUT (or DMM) are both RS-232?
Connect the computer COM port to COM1 of the molbox. Connect the DUT (or DMM) to COM2
of the molbox and set the DUT or DMM to be read on Ref COM2 (see Section 10.3.4
and/or 13.3.1). This solution is only possible with
DHI
molbox references that have a COM2.
Troubleshoot communications with remote devices (references, DMMs, DUTs, etc.)?
Use
[Tools]
,
[Remote Communications]
(see Section 13.6) to interface directly with the
device, send command strings and display the responses. Be sure to refer to the device’s
User’s Manual for assistance specific to the device. Changes to interface settings made in
[Tools]
,
[Remote Communications]
are temporary. If changes were necessary to
establish communications, these changes must be made in the device’s Hardware
Definition (see Section 10.3).
Reposition the main program toolbars?
Right click the
<Main Toolbar>
or the
<Control Toolbar>
to get a popup menu of options
to reposition the toolbars (see Sections 6.5 and 6.6).
Determine the “characters to strip” from the response of a remote DUT or DMM?
Use
[Tools]
,
[Remote Communications]
(see Section 10.3) to query the device and
observe its response string.
Use the same device for more than one task in the Hardware Definition (e.g., DMM
also measure frequency)?
Set up the instrument in both Hardware Definitions and select it for both functions in the
System Configuration (see Section 10). Make sure the same remote interface selection is
used in both setups.
Log data not already logged by COMPASS?
Use
[Setup][Hardware]<Auxiliary>
(see Section 10.3.7) to create the interface for the
device that will be used to measure the desired output. An example Auxiliary Data setup
of the valve voltage measuring ability of the molbox was installed with
COMPASS
. After the
device has been setup, select it in a Test Definition (see Section 9.5.10) or select the
device in initialization of
[Run DUT]
or
[Run molbox]
.
Log data without running a test or take data over an extended period of time?
Use
[Run],[Run DUT]
or
[Run molbox]
(see Section 7.3) to begin data acquisition with
the molbox, (and DUT) and other support devices. Select the
[Create data file]
option on
the
<Run Toolbar>
. Then use the data acquisition options to log discrete data points or
take points over time (see Section 6.5).
