There are four modes classified by trigger mode:
Trigger mode
Meaning
Terminate manually
Press [TEST] to terminate the test manually
Termination of external IO
Termination test via external EXT.IO signal port
Termination of external command
Termination test by RS232, LAN port command
EXT.SW port trigger
Terminate test by external trigger switch on the panel
Automatic termination. After the test mode is selected, the test is terminated when the test and
sorting meet the predetermined termination conditions during the test.
Classification by test mode is as follows:
Auto Test Mode
Meaning
CONT mode
Continuous measurement until test timing
FAIL STOP mode
When the test reaches FAIL sorting judgment, the test stops
PASS STOP mode
When the test reaches the PASS sorting judgment, the test stop
SEQ mode
EXT.IO signal STOP signal is low test terminated
Once the test is terminated, the high voltage at the test terminal stops outputting. The voltage at
the test port may remain high due to the capacitive characteristics of the component under test,
and the STOP light will continue to flash.
Chapter 5 PLC Interface
The EXT.I / O terminal on the rear panel of the instrument supports external control, provides test
and comparison judgment signal output, and accepts input START and STOP signals.
Start signal: the instrument will start the test when the 1-4 pins are shorted for more than 200ms;
Reset signal: the instrument will stop testing when the short circuit of pins 1-3 is greater than
200ms;
Pass signal: When the instrument judges the sorting result as pass, pins 6-7 will be short-circuited;
Unqualified signal: When the instrument judges the sorting result as unqualified, pins 8-9 will be
short-circuited..
