Eaton SEFELEC 5 Series User Manual

User manual SEFELEC 5x Series 23 v1.06Dielectric strength, 500 VAAt current threshold IMAXAdjustable amplitude of from 0.01 mA to 110 mA in steps of 0.01 mA.The device continuously measures the current flowing in the sample under test and compares itaccording to two possibilities:The high threshold > 0.01 mA; the low thresh-old is fixed at 0.00 mAIf the measured current is greater than or equalto the threshold, the test is declared NG: Cir-cuit break; if the current is < high threshold thetest is declared PASSThe low threshold > 0.01 mA and the highthreshold is > low thresholdIf the current measured is inside of the rangedefined by the thresholds, the test is PASS, if itis 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 0.0 mA to 109 mA. The use of IMIN en-sures 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 permanent currentThe current reading is obtained through a shunt located directly in the test circuitResolution 11,000 pointsAccuracy0.01 mA to 110.00 mA AC ±(2.5% + 20 μA)0.01 mA to 110.00 mA DC ±(2.5% + 20 μA)The message 'POWER CURRENT' as well as the "value" '- - - - mA' are displayed on the LCDscreen when the current exceeds 110 mA AC or DC.The AC current displayed is the real RMS current. I.e. it is calculated according to the formula:
