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(R display counts/ I display counts) < 0.2, Resolution: 0.1mΩ

±(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.
Limit
Hi-Limit : 0.1 ~ 510mΩ; Low-Limit : off, 0.1mΩ~ Hi-Limit Value, 510mΩmax.
