Setting Other Test Conditions

Withstanding Voltage and Insulation Resistance Tests

Judgment wait time (Wait Time)

You can set the time between when a DC withstanding voltage or insulation resistance (IR) test

starts (when you press START) and when judgment actually begins.

During a DC withstanding voltage test or an insulation resistance test, when the test voltage is

applied to an DUT with a capacitive component, a large charge current may flow until charging is

completed, or the insulation resistance may be measured at a value lower than its actual value

because of the charge current. By setting a judgment wait time, you can prevent incorrect

judgments caused by breaches to the upper or lower limits that occur because of the effect of the

charge current that flows to the capacitive load during the voltage rise time.

● Operation during a DC withstanding voltage test (example in which the test voltage is

reached over the specified voltage rise time)

When the voltage rise time elapses, the LOWER judgment begins. When the judgment wait

time elapses, the UPPER judgment begins.

● Operation during an insulation resistance (IR) test (example in which the test voltage is

reached over the normal voltage rise time)

When the voltage rise time elapses, the UPPER judgment begins. When the judgment wait time

elapses, the LOWER judgment begins.
