Output Frequency | 50Hz / 60Hz |
Resistance Range | 0.1 ~ 510 mΩ |
Resistance Resolution | (R display counts/ I display counts)≧0.2, Resolution: 1mΩ(R display counts/ I display counts) < 0.2, Resolution: 0.1mΩ |
Resistance Accuracy | ±(2% of reading + 0.5% of full scale) |
Offset | A predetermined value can be subtracted from the measured value and the result of subtraction can be display The result of subtraction can be compared with a Good/NO Good judgment reference value, and the result of comparison can be use for the Good/NO Good judgment |
Offset Range | 0 ~ 100mΩ |
TestTime | 0.5 ~ 999 sec., continue |
Waveform | Sine wave |
GO/NG Judgment | 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. Ifno abnormal state is detected during the test time, a good judgment is made and a good signal is deliver. |
