Test Procedures
6.1.4 Setting the Test Time
This procedure is to set the test period of time during which the tester remains in the
TEST-ON status (status that the tester delivers the test voltage). When this period
elapses without any FAIL judgment, the tester terminates the test and gives a PASS
judgment. You can turn OFF the timer function if you don’t need it.
• Test time and pause period are limited by setting upper cutoff current. “ON
30min” of the front panel character shows a maximum test time and “OFF 30min”
shows a minimum pause period. For details, refer to section 10.1, “Basic Perfor-
mance” (Page 10-2 ).
Setup procedure
1. Adjust the preset test period with the or key.
If you press the SHIFT key at the same time, the adjusting speed is increased
by a factor of 10. The test period is displayed on the TIME display.
2. To turn ON (or OFF) the timer function, press the ON/OFF key.
When it is turned ON, the “TIMER ON” message appears.
Resolutions and display formats
• The ON/OFF key is enabled when the tester is in the READY status (status that
the “READY” message appears) and the “KEYLOCK” message is OFF. They are
disabled when in the TEST-ON status (status that the “TEST” message appears)
or when the tester is delivering the result of PASS/FAIL judgment (when the
“PASS” message or the “FAIL” message appears).
• The timer function is not in effect unless the “TIMER ON” message is displayed,
even when the test period is displayed on the TIME display. As the timer function
is not in effect, the test does not terminate even when the preset test period elapses
and the tester makes no PASS judgment.
• If your test speci fi cation requires that the test period for the DUT must not be
shorter than the speci fi ed test period even by a very short period, increase the pre-
set test period by one digit.
• When you turn OFF the POWER switch immediately after you have changed the
test time, no setting value may be stored. Wait for fi ve seconds or more after the
setting change, and then turn OFF the POWER switch.
