6.2.4 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 has elapsed without any FAIL
judgement events, the Tester terminates the test and gives a PASS judgement. You can turn OFF the
timer function if you don’t need it.
Caution
• Test time and pause period are limited by setting upper cutoff current.
"ON
…
" of the front panel character shows a maximum test time and
"OFF … " shows a minimum pause period. For details, refer to chapter 9
"Specifications" (Pages 9-9, 9-10 and 9-11).
Setting Procedure
Step 1
Adjust the preset test period with the keys 14 . If you press the
SHIFT
key 16
at the same time, the adjusting speed is increased by a factor of ten. The test period is
displayed on the TIME display
26
.
Step 2
To turn ON (or OFF) the timer function, press the ON/OFF key
15
. When it is
turned ON, the
TIMER ON
message
27
appears.

Caution
• The keys are enabled when the Tester is in the READY status (status that
the
READY
message
28
appears) and the
KEYLOCK
message
33
has
disappeared. They are disabled when in the TEST-ON status (status
that the
TEST
message
29
appears) or when the Tester is delivering the
result of PASS/FAIL judgement (when the
PASS
message 30 or the
FAIL
message
31
appears).
• The timer function is not in effect unless the
TIMER ON
message
27
is
displayed, even when the test period is displayed on the TIME display 26 .
As the timer function is not in effect, the test does not terminate even when
the preset test period has elapsed and the Tester makes no PASS judgement.
• The accuracy of the test period is
±
20 ms. If your test specifications
require that the test period for the DUT must not be shorter than the
specified test period even by a very short period, increase the preset test
period by one digit.
