- Standard RS-232 interface, GPIB optional
| Grounding Resistance Test | |
|---|---|
| Output Current | AC: 3 ∼ 45 |
| Load Regulation | 1% + 0.3 A |
| Resolution | 3 ∼ 30A: 0.01A 30.1 ∼ 45A: 0.1A |
| Current Accuracy | ± (1.5% of setting + 0.5% of full scale) |
| Output Frequency | 50 Hz/60 Hz |
| Resistance range | 0.1 ∼ 510 mΩ |
| Resistance Resolution | (R display counts/I display counts)≥ 0.2,Resolution: 1 mΩ (R display counts/I display counts) < 0.2, Resolution: 0.1 mΩ |
| Resistance Accuracy | ± (2% of reading + 0.5% of full scale) |
| Offset | A predetermined value can be subtracted from the measured value and the result can be displayed The result of the subtraction can be compared with a Good/NO Good judgment reference value, and the result of the comparison can be used for the Good/NO Good judgment |
| Offset Range | 0 ∼ 100.0 mΩ |
| Test time | 0.5 ∼ 999.0 sec., continuous |
| Waveform | Sine wave |
| GO/NG Judgement | |
| GO/NG Conditions | A no-good judgment is made when a resistance greater than the high limit value Is detected A no-good judgment is made when the output current is cutout and a no-good Alarm signal is delivered If no abnormal state is detected during the test time, a good judgment is made and a good signal is deliver |
| Limits | HI-LIMIT: 0.1 ∼ 510.0mΩ LOW-LIMIT: OFF, 0.1mΩ ∼ HI- LIMIT Value 510.0mΩ MAX |
