TOS9300_Leakage Current Test-Measurement function

ItemTOS9303LC
Measurement itemsTCTouch current measurement
Measurement methodUses a measurement circuit network representing the impedance of a human body and measures the voltage drop across a reference resistance to calculate the touch current.
Probe settingsEnc-PeA terminal: measurement terminal (for connecting to the enclosure of the EUT) B terminal: open
Enc-EncA and B terminals: measurement terminal (for connecting to the enclosure of the EUT)
Enc-Liv Enc-NeuA terminal: measurement terminal (for connecting to the enclosure of the EUT) B terminal: open
PCCProtective conductor current measurement
Measurement methodMeasures the voltage drop across a reference resistance inserted in the middle of the protective ground line to calculate the protective conductor current. The measurement impedance is 150 Ω.
PatientPatient leakage current measurement
Measurement methodUses a network conforming to IEC 60601 and measures the voltage drop across a reference resistance to calculate the patient leakage current.
MeterMeasures the current flowing or voltage applied across the A and B terminals (simultaneous measurement not possible).
Measurement methodCurrent measurementUses a measurement circuit network representing the impedance of a human body and measures the voltage drop across a refer-ence resistance to calculate the current flowing across the A and B terminals.
Voltage measurementMeasures the voltage applied across the A and B terminals.
Current measurement modeDCEliminates AC components and measures only the DC component.
RMSMeasures the true rms value (switch AC and AC+DC)
Peak *1Measures waveform peak values

*1 Current measurements may not be stable due to the effects of the power supply line waveform or the wiring environment between the product and the EUT.
