11 Continuity Delay Timer
The CONT Delay Timer option allows you to use the Continuity test when the DUT
requires a stabilization period before the reading can be taken.
In this option the standard Dwell time parameter is replaced by the new Delay time
parameter. Therefore the Dwell time parameter is not available when the option has
been activated. During the Delay period the Max or Min Limit judgments are disabled
and the DUT has time for stabilization. The Max and Min Limits will be processed after
the Delay time period has expired.
Edit Dwell Bus Command EDW and EDW? are used also to control Delay time of the
CONT Delay Timer option.
There are no specification changes as a result of the installation of this option.
NOTE: If the GPIB or Printer Options are installed, the System menu will look
different and will consist of two pages with the Dual Test parameter appearing
on the second page.
The rear panel remote interface is reconfigured to allow two test switches instead of
the standard reset and test inputs. The two test switches have to be pressed within
0.5 seconds to activate the test process. The two test switches must remain closed to
continue the test. If either of the test switches is released, the process will be shut
down immediately. The functions of the TEST and RESET switches on the front panel
will be disabled if the dual test switches are enabled. When the Dual Test parameter
is turned OFF, the TEST and RESET switches on the front and rear panel behave the
same as the standard instrument, and are controlled by the PLC Remote On/Off
selection.
12 Negative DCW
The Negative DCW option, when activated, adds another test field in the Setup Test
