INTRODUCTION
GOOD WILL INSTRUMENT CO., LTD., accumulated over 30 years experiences in
electronic products’ research and development, is a pioneering manufacturer in IC
testers industry. The GUT-6000A, desktop design, is a newly launched and best
quality possible and multi-functions equipped product.
User’s friendly sets up by replacing another IC; the GUT-6000A continues to
undertake the task. The hard ware design of ''black-light'' function extends user’s
convenience for testing ICs in an inadequate light environment. The Buzzer key
built in various tones can easily identify the testing result. The unique capability
in identifying over 1800 CMOS/TTL digital ICs (up to 24 pins) surpasses the other
major digital IC testers.
The GUT-6000A feature such as built in ''auto search & test'' speeds to identify
and test IC. In addition, the ''loop'' design for continuously testing function is
intelligently applied to detect defective ICs and their stability. All these strengths
provide signicantly conveniences for digital IC testers.
All the GUT-6000A accumulated incalculable benets are to be discovered as
users utilize the value-added, multi-functions equipped tester. This is a best
choice for the factories, R&D sections, maintenance departments, laboratories as
well as academics because it really creates future with your business.

OPERATIONAL INSTRUCTIONS
1. OPERATIONAL PROCEDURES
STEP1. Plug in AC power cord, then switch power on.
The black light of LCD is on and presents software version.
It starts self-test.
STEP2. Auto search the IC number and test if an IC is on the socket.
STEP3. Use TTL/CMOS to switch the selection of ''TTL74'', ''CMOS40'' or
''CMOS45'' series ICs.
No system error found displays on the LCD
System error shows on the LCD if it is detected.

2. TESTING PROCEDURES
STEP1. Put IC on the socket and IC’s bottom line up with socket. Pin 1 side
faces up.
STEP2. Input the IC number such as the TTL 74LS244, and user types in IC
number in order.
STEP4. Repeat test by replacing a new IC, then press .
STEP5. Re-type the IC’s numbers for other another test.
Note. ''Pass'' may also happen to some logic function compatible but
different number’s two ICs if their numbers are exchanged with each
other to test.

3. AUTO LOOP TEST
1. When an IC is tested, the test results appear unstable such as sometimes
good and sometimes not. The auto loop test is designed to detect this kind of
problem.
2. When a big quantity of same number of IC need to be test, the auto loop test
is speeding the process.
STEP1. Put IC into the socket and IC’s bottom line up with socket. Pin 1 side
faces up.
STEP2. Input the IC number such as the TTL 74LS244 device, and user
types in IC number in order.
STEP3. Press , then the test is running. Follow-up test result is
displayed on the LCD.
Error found was displayed on the LCD, ''Error in: nnnnn'', nnnnn means the
number of the error times.
STEP4. If take the IC away from the socket, the system will back to waiting
IC put in situation.
STEP5. Put IC into the socket, tight down the pin-stabler, the system will stat
the ''auto loop test''.
STEP6. Press any key to stop the ''auto loop test''.

4. AUTO Search
STEP2. Put IC into the socket and tight down the pin-stabler. System will begin to
process. If the test is correct, the LCD will shows ''PASS''. If the tests is
incorrect, the LCD will show ''FAIL''.
STEP3. Take the IC away the socket. The system will back to waiting IC situation.
Repeat the above steps, the auto search function will continue.
STEP4. If the system search for new IC number, not the number which you press
in, but the compatible IC. In this situation, no need to take the IC away, only
need to press ''AUTO'' key. The system will switch to the new IC number.
Repeat to press ''AUTO'' to switch to new IC number.
STEP5. Press any key but not ''AUTO'' to quit the auto search function. The LCD
will show ''CANCELAUTO''. Release to the original mode.
Note: IC number’s search result is presented from a small number to a bigger one.
For example, IC 74520 is found earlier than IC 74521.
Note: The biggest number for counter is 65535, if the over this number, the
counter will start from ''0''.
This test aims to search the unknown IC number.
STEP1. Press ''AUTO'' key, the LCD will show ''AUTO SEARCH''. The ''AUTO
SEARCH'' function is beginning. For example the TTL 74244.

KEY CODE DESCRIPTION
Input device number without series key code, it runs by switching TTL/CMOS
selection.
Ex1. IC TTL 74138
An user switches TTL/CMOS to ''TTL 74'', then input 1 , 3 , 8 in order.
Ex2. CMOS 4020
An user switches TTL/CMOS to ''CMOS40'', then input 2 , 0 in order.
Ex3. CMOS 74HC4040
An user switches TTL/CMOS to ''CMOS40'', then input 4 , 0 in order.
Some ICs have different pin arrangements despite that have the same number. In
that situation, various key codes information is supplemented for this group’s ICs (see
appendixes).
Users may come upon difcult in some generic type’s ICs. For example, an IC is
numbered TTL 7454 and 74H54, the user identies the difference with ''XXX'' and
''9XXX''. If the user is interested in testing TTL 74H54 device, then selects ''TTL 74''
rst. Then types 9 , 0 , 5 , 4 .
