Model

510B

Resistance Measure

0~150.0mΩ

Accuracy

±2%±3 count of full scale (1~30A)

Test Current Output

1~30A AC constant current adjusted Max Current 30A AC Max Voltage 6V

Output Ammeter

Digital display

Scale

0~30A AC(±1% ?3 counts of full scale)

GO/NG Judgment

Judgment

Judged NG when measure value is greater than reference value, followed by NG alarm
output and output cutoff
Judged GO if there are no abnormalities after the set amount of time has passed,
followed by GO signal output

Reference Value

Setting Range

Randomly set between 5~100% of the measuring range

Judgment Accuracy

?5% of full scale with respect to reference value 1~5A
±3% of full scale with respect to reference value 5~30A

Offset Function

Allows to preset a short circuit resistance value and makes a GO/NG judgment by
comparing with the reference value after subtracting the short circuit resistance value.

Offset Range

Up to 100mΩ
