TOS9213S/ TOS9213AS
10.1 Withstanding Voltage Test Mode
*
1 Limitation on output
The tester’s withstanding voltage generator is designed to radiate half as much heat as the rated output, in consideration of
the size, weight, cost, and other factors of the tester. It is therefore necessary to use the tester within the ranges specified
below. Operations deviating from these ranges may heat the output section excessively, thereby activating the protective
circuit. In such a case, suspend the test and wait until the temperature falls to the normal level.

2 About the discharge time setting
If you set the discharge time to 0.0 s or if the voltage between the output terminals exceeds approximately 30
V
even after
the specified discharge time has passed, the TOS9213S/ TOS9213AS will continue discharging until the voltage between
the output terminals falls below approximately 30
V
.
