|---|---|---|---|---|---|---|---|---|
| Current judgment operation | 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 current greater than or equal to the Upper limit is detected. For DCW, judgment is not made during the judgment delay (Judge Delay). | ||||||
| Display | “U-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 current less than or equal to the Lower limit is detected. Judgment is not made during Voltage rise time or Voltage fall time of an ACW test. | ||||||
| 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 set-ting. 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 approx. 1 V/s. | ||||||
| Display | “ Upper-FAIL(dv/dt)” is displayed. | |||||||
| Buzzer | On | |||||||
| SIGNAL I/O | The U-FAIL signal is generated continuously until a STOP signal is received. | |||||||
| Upper limit setting range | AC: 0.01 mA to 110.00 mA, DC: 0.01 mA to 21.00 mA | |||||||
| Lower limit setting range | AC: 0.00 mA to 109.99 mA, DC: 0.00 mA to 20.99 mA, OFF. Setting 0.00 is equivalent to OFF. | |||||||
| Judgment accuracy *1 *2 | ±(1 % of setting + 5 μA) | |||||||
| Current detection method | Compares to the reference value using the following method. Calculate true rms values, convert mean-value responses to rms values | |||||||
| Response speed (filter) switching | Switches the current detection response speed (sensitivity) used in UPPER FAIL judgment between five levels in ACW and DCW tests. | |||||||
*1 During AC voltage tests, current also flows in the stray capacitance of items such as the test leads and tools. For details on stray capacitance, see “Stray Capacitance of AC Withstanding Voltage Tests” *2 When the temperature and humidity are high, erroneous current from the product’s internal and external high-voltage wiring sections to ground increases. When the humidity exceeds 70 %, an erroneous current of about 50 μA may be generated.
