Mode

Ground Bond

Grounding Resistance Test

Output Current

AC : 3 ~ 4

Load Regulation

1 % + 0.3 A

Resolution

3 ~ 30A, 0.01A / 30.1 ~ 4, 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(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.

Limit

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