Setting the Test Time
4.9 Setting the Test Time
The time period from the elapsed voltage rise time to the end of a test is set. If the upper-limit or
lower-limit judgment is not made within the test time, a pass judgment is determined for the test
target and the test is automatically ended.
When the test is not to be ended automatically, set the test time to [CONT] . When [CONT] is set,
the test is continued until the STOP button is pressed for each test or the following conditions are
met.
DCW: fail judgment
IR: Insulation resistance test end mode (p. 108)
IMPORTANT
• A range movement by the auto-range function may take time. The test may end without
displaying the measured value if a short test time is set. When the auto-range function is
selected, check the time until the measured value is stabilized and set the test time.
See “4.7 Setting the Auto-Range Function” (p. 46).
• The measured value may not be stabilized due to environmental influences, such as
temperature and humidity. Check the time until the measured value is stabilized and set the
test time.
• Depending on the test target, the measured value may change as time passes.
Example: When the ground to ground capacitance is high, the resistance value drops as time
passes.
When an improper test time is set, false judgment could occur.

Default setting: 1.0 s
The lower limit is set by [RISE TIME] (voltage rise time)
and [DELAY] (judgment wait time).
[DELAY] < [RISE TIME] + [TEST TIME]
(Only when [DELAY] is not set to off)
