Eaton SEFELEC 5 Series User Manual

User manual SEFELEC 5x Series 20 v1.06Dielectric strength, 50 VAAt current threshold IMAXAmplitude adjustable from 0.001 mA to 10.000 mA in steps of 0.001 mA.The device continuously measures the total current and the real current (AC) circulating throughthe sample under test and compares the latter according to two possibilities:The high threshold > 0.000 mA, the low thresh-old is fixed at 0.000 mAIf the measured current is greater than orequal to the threshold, the test is declaredFAIL: Circuit break; if the current is < highthreshold the test is declared PASSThe low threshold > 0.000 mA and the highthreshold is > low thresholdIf the current measured is inside the rangedefined by the thresholds, the test is PASS, ifit is outside the test is declared FAIL: CircuitbreakMin. current limit IMINIn the sensing modes above, it is possible to specify a minimum value of current flowing in thesample under test. The value of IMIN is adjustable from 0.000 mA to 10.000 mA. The use ofIMIN ensures that the test sample is correctly connected to the deviceWithout sensingIn this case no current monitoring is performed.There is no adjustment of the output voltage in relation to the loadWarning: Permanent use of the device on a low-impedance charge can resultin overheating of the amplification stage, with consequent stoppage of thegenerator for safety reasons.Measurement of the TOTAL permanent currentThe reading of the total current (resistive and capacitive) is obtained through a shunt locateddirectly in the test circuitResolution 10,000 pointsAccuracy0.001 mA 9.999 mA AC ±(1.5% + 2 μA)0.001 mA to 9.999 mA DC ±(1.5% + 2 μA)In DC the accuracy is guaranteed for charging resistances > 1 MΩ.
