Grounding Resistance Test
Output Current	AC : 3~45A
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	50Hz / 60Hz
Resistance Range	0.1 ~ 510 mΩ
Resistance Resolution	(R display counts/ I display counts)≧0.2,Resolution : 1mΩ
Resistance Resolution	(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
Offset	■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	0~100.0mΩ
Test Time	0.5 ~ 999.0 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.
	■ If no abnormal state is detected during the test time, a good judgment is made and a good signal is deliver.
