3-38 Basic Operations TOS9200/9201
3.6.2 Settings on the IR2 screen
Setting the voltage rise time (RISE TIME)
The rise time between the start voltage and the test voltage can be set to 0.1 s
through 200 s (at a resolution of 0.1 s for the 0.1 s to 99.9 s range and 1 s for the 100
s to 200 s range).
When the cursor is to the right of RISE, settings can be made using the rotary knob.
1. To move the cursor to RISE, press the F2 key (RISE TM). (The
keys can also be used.)
2. Using the keys, move the cursor to the target digit.
3. Using the rotary knob, set the rise time.
The fi gure (V/s) in parentheses represents the voltage increase per second calculated
for reference using the set value.
If the value cannot be displayed in three digits, “---” is displayed instead.
Setting the WAIT TIME
In DC insulation resistance testing, if a test voltage is applied to a DUT that contains
capacitive elements, the measured insulation resistance will be below the optimal
value due to a charge current, until charging is completed. To avoid upper fail judge-
ment by the charge current, a wait time must be provided from the starts of START
VOLTAGE, and upper fail judgement will be ignored during wait time.
Set the wait time to 0.3 s through 10 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.
1. To move the cursor to the right of WAIT, press the F4 key (WAIT TM).
(The keys can also be used.)
2. Using the rotary knob, set the wait time.
