search mode

This feature allows the type number of an unknown IC to be determined,
provided the IC is actually contained in the ChipMaster Compact library,
and it is a correctly functioning IC. This facility is useful when the IC type
number is illegible or has been removed.
Use the MODE/CLEAR key to choose SEARCH mode, insert the
unknown IC into the socket and press the TEST/EXEC key. You will be
prompted to choose the number of pins of the IC you wish to identify -
use the MODE/CLEAR key to select from 8 to 40 pins or 'QUIT' to
abandon this mode.
SEARCH or to quit as required.
During the identification process the display will indicate the number of
ICs identified (IDENT:) and will show graphically how far through the
library the SEARCH has progressed. At the end of the SEARCH, a list
of all the similar ICs will be scrolled onto the display. The list may be
scrolled again by pressing the TEST/EXEC key. The scrolling message
can be cancelled by pressing the MODE/CLEAR key, or paused by
pressing and holding a numeric key.
If the IC cannot be identified the message "Not in Library" will be
displayed. This means either that the IC is not in the library or it is non-
functional. Note that if the Compact detects excessive supply current
(ICC! or BAT! warnings), the IC will not be identified during the
SEARCH, but can still be tested in SINGLE mode.
If you have a user library present the search will extend to user ICs in
that library also. However, CompactLink contains a facility for excluding
ICs from the search if required.

self test mode

This feature allows you to check the integrity of the unit, including the pin
drivers and receivers, power supplies and other internal hardware. The
test executes automatically at switch on, but you can if you wish perform
a self-test at any time by selecting Self-Test (DIAGS) mode using the
MODE/CLEAR key and pressing TEST/EXEC.
If a fault is discovered a brief description will be displayed which will help
our engineers to locate and rectify the fault. This message should be
noted and quoted in any correspondence relating to a unit fault. Contact
