Disable ground check
Operating CPC 100 with the "Disable ground check" check box selected can
cause injury or possibly death of the operating staff if the power supply is not
metallically separated and the PE (protective connection) is defective.
An error message (313) appears if either the PE connection is defective or the
power supply has no galvanic connection to ground. In this case, make sure that
the PE connection is intact. If the PE connection is intact and the error message
still appears, select the "Disable ground check" check box.
Default freq.
The "Default freq." data entry field allows you to enter the default frequency. For
the default value associated with different instantiation procedures, see
”Instantiation procedures” on page 33 of this chapter.
Auto Save
As the name implies, the "Auto Save" feature automatically saves the current
test settings in fixed intervals. These intervals can be set in the Auto Save box.
There are three time intervals available (10, 30 or 60 minutes), and the option
OFF which disables Auto Save.
Auto Save saves all actual data to a file named
lastmeas.xml
. So depending
on the set time interval, in case of a system crash,
lastmeas.xml
may contain
more actual data than the last manually saved test. The file is created during the
next booting process.
When Auto Save saves test settings, it pops up a dialog notifying you about it.
Auto Save works in Test Procedure Overview, File Operations or Options
without any restrictions. In Test Card View, Auto Save does not work as long as
a test is running, or as long as inputs are measured (for example, in Quick).
In a case like this, Auto Save repeats the attempt to save the test settings in
intervals until it succeeds, that is, until the test is finished and it can save the
data. After this, Auto Save returns to the set time interval.
Note: After CPC 100 has been rebooted, the "Disable ground check" check
is cleared for safety reasons.
