The Optima software contains a convenient tool for isolating the cause of a continuity
failure. Selecting the <Display> option presents you with a package diagram
outlining the pin(s) that are believed to be causing the failure:
Pinmap showing continuity failures; pins displayed here in gray are not making
proper contact. On user interface, pins not making proper contact are displayed in
red.

Device>Read
Selecting Device>Read retrieves the data contents of the device in the socket and
reads them into memory. While the read operation is in progress, the status window
displays the term ACTIVE and shows the percentage of completion. When the read
operation is complete, a PASS or FAIL message indicates its success or failure. Using
the <Read Device> button in the Device Action section yields the same results. Any
additional information related to this read operation is also displayed in the Messages
section of the screen:
Successful completion of a READ operation
When using a Multisyte programmer, insert the device in the left-most TOP for the
read operation.

Device>Blank Check
The Blank Check feature may be enabled or disabled depending on the device
selected. If the feature is enabled, selecting Device>Blank Check lets you determine
if the device under test is truly empty. If the blank check passes, the device is truly
empty. Otherwise, some of the device locations may have data in them.
UV erasable devices must be erased under ultraviolet light in accordance with the
manufacturer’s instructions before programming.
Note: Not all UV erasable devices are guaranteed to arrive blank
from the manufacturer. If they are not blank, simply erase
them according to the manufacturer’s guidelines for the
device under test.
The Blank Check function is performed prior to all programming functions. You may
also initiate the Blank Check operation from the <Blank Check> button in the Device
Action section of the screen.
