Update the
<Tare Display>
with the last saved tare information for the FPG.
FPG pressure is calculated only after valid tare data is available.
Initialize the RS232 interface of the FPG. An RS232 cable must be connected to the
FPG COM1 port and an RS232 port on the host PC. The host PC port must be specified
using the
<System Setup><Interface>
option (see Section 6.6.2.2).
Initialize the remote interface of the VLPC if it is enabled in the system configuration
(see Section 6.6.2.1). An RS232 cable must connect the FPG COM2 port to the
COM1 port of the VLPC. There is no software setup required to specify port and
communications settings. When the VLPC is enabled and an interface error occurs,
the initialization process is aborted.
The current valve state, reference pressure and lubrication pressure are queried to
determine the active measurement mode. The mode that most resembles the valve and
pressure configuration within the FPG is then specifically set. When the mode is not fully
defined by the pressure and valve state, a prompt will occur to select the desired mode to
operate on.
Initialize the remote interface of the DUT if enabled in the
<Current Configuration>
.
The DUT must be connected to the host PC according to the DUT interface selections in
the
[Config], [System Setup], <Interface>
option (see Section 6.6.2.2).
Initialization is complete.
6.5.2 [RUN MONITOR]
[Run Monitor]
automatically refreshes the output of the FPG and allows use of all discrete
controls provided by FPG Tools. There are no defined steps in this run mode. Use this run
mode to monitor the FPG like a standalone instrument when data acquisition is not
necessary. Of the three run modes,
[Run Monitor]
most closely resembles a simple
instrument interface. Use the control toolbar and the
<VLPC Interface>
window to set
pressure and change the state of the FPG see Sections 6.4.2 and 6.3.6.
6.5.3 [RUN W/POINT LOG]
This option is identical to the
[Run Monitor]
option with the added ability of data acquisition.
When the option is selected, a standard file selection dialog displays to allow the entry of the
name of the data file. A default data file name is automatically provided by FPG Tools (see
Section 9.2.1). Data points can be taken at any time by using the
[Take Point]
,
[Average
Point]
or
[Auto Point]
options (see Section 6.6.4.2). There is no time limit or specific
sequence required with this option.
All active configuration information available at the time
[Run w/Point Log]
is selected is
logged in the header of the data file. Changes made to any parameter logged in the header
is not reflected in the completed data file.
For best use of the data file, do not make changes to the program configuration after the
run mode begins. Most changes will not be reflected in the data file.
6.5.4 [RUN TEST SEQUENCE]
[Run Test Sequence]
is available only after one of the other run modes have been selected.
Use this option to execute a test sequence created with the
<Test Sequence Editor>
(see
Section 6.6.5). FPG Tools automatically sets each test pressure and averages the results
according to the test sequence. When all test cycles are complete, FPG Tools automatically
sets
[Run Monitor]
mode and vents all system pressure. For this reason, test sequences
are a good way to safely run long, multi cycle tests overnight. The steps involved with
running a test sequence are described below.
