| Behavior based on judgment | The output is shut off when a judgment is made. Buzzer volume level can be set in the range of 0 (OFF) to 10 for pass and fail separately. In an auto test, the buzzer is valid only for the judgment that takes place at the end of the program. | ||||||
| UPPER FAIL | Judgment method | UPPER FAIL results when a resistance greater than or equal to the Upper limit is detected. Judgment is not made during or Voltage rise time. | |||||
| Display | “Upper-FAIL” is displayed. | ||||||
| Buzzer | On | ||||||
| SIGNAL I/O | The Upper-FAIL signal is generated continuously until a STOP signal is received. | ||||||
| Lower FAIL | Judgment method | LOWER FAIL results when a resistance less than or equal to the Lower limit is detected. Judgment is not made during the judgment delay (Judge Delay). | |||||
| Display | “L-FAIL” is displayed. | ||||||
| Buzzer | On | ||||||
| SIGNAL I/O | The Lower-FAIL signal is generated continuously until a STOP signal is received. | ||||||
| PASS | Judgment method | PASS judgment is made if U-FAIL or L-FAIL has not occurred when the test time elapses. | |||||
| Display | “PASS” is displayed. | ||||||
| Buzzer | On (fixed to 50 ms) | ||||||
| SIGNAL I/O | The PASS signal is generated for the length of time specified by the Pass Hold setting. If Pass Hold is set to Infinity, the PASS signal is generated continuously until a STOP signal is received. | ||||||
| Voltage rise rate judgment operation | Monitors the voltage rise rate during Voltage rise time. This is valid when Auto setting of the judgment delay (Delay Auto) is set to on and the output voltage is 200 V or more. The output is shut off when a judgment is made. Buzzer volume level can be set in the range of 0 (OFF) to 10 for pass and fail separately. | ||||||
| dV/dt FAIL | Judgment method | When the voltage rise rate (dV/dt) is less than 1 V/s. | |||||
| Display | “ Lower-FAIL(dv/dt)” is displayed. | ||||||
| Buzzer | On | ||||||
| SIGNAL I/O | The L FAIL signals are generated continuously until a STOP signal is received. | ||||||
| Upper limit setting range | 0.001 MΩ to 100.000 GΩ (in the range up to the maximum rated current), OFF | ||||||
| Lower limit setting range | 0.000 MΩ to 99.999 GΩ (in the range up to the maximum rated current), OFF. Setting 0.000 is equivalent to OFF. | ||||||

*1 Making judgments on 200 μA or less requires at least 3 seconds after the rise time ends. Making judgments when the low pass filter is set to on requires at least 10 seconds after the rise time ends. *2 Humidity: 70 %rh or less (no condensation), when there is no interference caused by wobbly test leads or other problems. *3 If the grounding mode (GND) is set to low in a highly humid environment, leakage current to ground will be generated from the high-voltage wiring sections inside the product and the high-voltage wiring sections between the product and the EUT. This leakage current ranges from several nA to several tens of nA depending on the usage and wiring conditions of the optional TOS9320 high voltage scanner and greatly affects measurement accuracy. The effects of leakage current can be reduced by making measurements with the offset enabled. *4 Add 10 % to the accuracy when measuring 100 V or less. *5 Add 5 % to the accuracy when measuring 100 V or less. *6 When the measured current is limited to 100 nA or more (no condensation) when the humidity is 50 %rh or less, no external disturbance is present such as swinging test leads, and the offset is enabled.
