|---|---|---|---|---|
| Judgment method and judgment operation*1 | Function | The output is shut off when a judgment is made. Beep volume level can be set for PASS and FAIL separately. | ||
| 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 | Shown on the display. | |||
| Beep sound | On | |||
| SIGNAL I/O | The U FAIL signal is generated continuously until a STOP signal is received. | |||
| LOWER FAIL | Judgment method | Lower limit (Lower) is detected or when there is an abnormality during the voltage rise. | ||
| Display | Shown on the display. | |||
| Beep sound | On | |||
| SIGNAL I/O | The L-FAIL signal is generated continuously until a STOP signal is received. | |||
| PASS | Judgment method | PASS judgment is made if Upper-FAIL or Lower-FAIL has not occurred when the test time elapses. | ||
| Display | Shown on the display. | |||
| Beep sound | ON (fixed at 0.2 s regardless of Pass Hold setting) | |||
| 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. | |||
| Upper limit setting range | 0.001MΩ to 10.000GΩ | |||
| Lower limit setting range | 0.000MΩ to 9.999GΩ | |||
| Judgment accuracy (common between Upper and Lower)*2 *3 *4 | Measurement accuracy + 2 digits | |||
*1 In the following conditions, charging current may activate a FAIL judgment or the protection function: EUT capacitance: 2μF; Rise Time: 1.5 seconds or less; Judge Delay: 2.0 seconds or less; Low Pass Filter: OFF
*2 Humidity: 70%rh or less (no condensation), when there is no interference caused by wobbly test leads or other problems.
*3 For judgments of 5μA or less, a test time of at least 1.0 seconds is necessary.
*4 When the low pass filter is set to medium, a test time of at least 0.3 seconds is required. When the low pass filter is set to slow, a test time of at least 0.5 seconds is required.
