Setting the WAIT TIME
In DC withstanding voltage testing, if a test voltage is applied to a DUT that con-
tains capacitive elements, a large charge current may flow until charging is com-
pleted. To avoid upper fail judgement by the charge current, a wait time must be
provided from the starts of START
V
OLTAGE, and upper fail judgement will be
ignored during wait time.
Set the wait time to 0.3 s through 30.0 s (at a resolution of 0.1 s).
When the cursor is located to the right of WAIT, the rotary knob can be used to
make settings.

Using the rotary kno

, set the
w
ait time.
• With the timer ON, if the wait time thus set exceeds the sum of the voltage rise
time and the test time, “O
V
ER WAIT” flashes on the LCD to indicate that testing
cannot be performed.
Setting the current detection response (RESPONSE)
By changing the integrated time constant of the current detection circuit, switch the
current detection response for UPPER FAIL judgement.
Integrated time constant
• SLOW
: Approximately 40 ms
• MID
: Approximately 4 ms
• FAST
: Approximately 0.4 ms
The current detection response can be set using the SHIFT + F2 keys (RESPONSE),
regardless of the location of the cursor. Each time the SHIFT + F2 keys are pressed,
the selection is switched among SLOW, MID, and FAST, in order.
